linux live usbGet Linux to boot, on your Mac, from a USB stick or external hard drive. A simple program called Mac Linux USB helps make a formerly complex process simple, and is a godsend for those without optical drives.

So you want want to boot Linux, from a flash drive, on your Mac? If you’re reading this, you probably already know it’s harder than it should be. Old standbys like uNetBootin How To Install Linux With Ease Using UNetbootin How To Install Linux With Ease Using UNetbootin We've already talked about Linux and why you should try it, but probably the hardest part of getting used to Linux is getting it in the first place. For Windows users, the simplest way is... Read More – while available for your Mac – do not create USB keys your Mac can actually boot. And you’ve probably noticed Ubuntu’s official, complex directions for the task. Maybe you’ve even tried them out, like me, and cursed when the resulting drive – which took hours to make – wouldn’t actually boot.

Don’t worry. There’s a simpler way – a GUI made specifically to get distributions like Ubuntu to boot on your Mac. It’s called Mac Linux USB, and it makes the process not only do-able, but easy.

All processes below were tested on a 2011 Macbook Pro – one that refused to boot any and all USB disks created by uNetBootin and similar tools. All you need for this process if your Mac and a blank USB stick – no Windows computer is required! The process primarily works with Ubuntu and derivatives, but could potentially work with other versions of Linux. Note that Macs cannot boot from the SD card reader – you’re going to need a USB stick or an external drive.

One more thing: If there is anything on your USB stick back it up now – we will likely delete everything on it during the process.

Step 1: Check And Format Your Drive

Note: this step might not be necessary for everyone, but for me made the process foolproof. Consider it recommended.

To get started, ensure your USB stick is properly formatted – we need a FAT32, MBR drive. In OS X, open up the Disk Utility How To Partition An External Hard Drive For PC Usage [Mac] How To Partition An External Hard Drive For PC Usage [Mac] As you may know, Mac formatting and PC formatting for external hard drives are totally different. Granted, it's possible you may already know how to partition an external hard drive DIY-style. Furthermore, your hard drive... Read More – you’ll find it in your Applications folder, under Utilities, or by using Spotlight. In the left pane you’ll see your current drives. Click your USB stick, then click Info.

linux live usb

From here you should see the partition scheme, which should say “Master Boot Record” as seen above. If this isn’t the case, don’t worry: you can easily format the drive the way we want it. Click the drive, then click Partition. Click the drop-down menu that says Current then click 1 Partition.

linux boot usb

Be sure to pick FAT as your filesystem, then click the Options button at bottom-left. Pick Master Boot Record:

linux boot usb

Proceeding from here will wipe your drive, so if you’ve backed up everything on it go ahead and apply the changes. You’re now ready for the second step.

Step 2: Putting Linux On Your USB Stick

Now that your disk is ready, let’s go ahead and set up Linux on it. You can do this manually, if you like, but let’s start by using a program called Mac Linux USB – it removes some of the busy work from the process. Go ahead and download Mac Linux USB – you’ll want to grab the semi-recent build linked to toward the bottom of that page (1.0 as of this writing).

This software is capable of downloading Mac-compatible ISOs of Ubuntu, Linux Mint and Zorin OS:

linux boot usb

Feel free to use this tool to download your preferred version of Linux, though note that the options are limited – and ISO files you find elsewhere may or may not work. (If you prefer downloading Ubuntu with Bittorrent, be sure to grab the file with “+Mac” at the end of the file name – other versions will not boot on your Mac).

Once you’ve got your Linux distro of choice, click “Create Live USB” and direct the program to your ISO. Then the software will get to work:

linux live

How long this takes depends on the size of the ISO and the speed of your drive, but it shouldn’t take more than a few minutes on most modern Macs. When it’s done you’ll see there are only two new folders and three new files on your drive. You can replace the ISO later manually if you want to switch Linux distros (more on that later) and the other file is an EFI application – firmware that allows your Mac to boot the ISO.

Step 3: Booting Your Disk

Now for the easy part: booting Ubuntu from your drive. Assuming you did everything correctly – including grabbing a Mac-bootable Linux distro – this should be easy. Just shut down your Mac, then turn it back on. When you hear the Mac “Chime”, press and hold the “Option/Alt” key. You’ll be shown all the bootable drives on your Mac, including your USB stick (which will be yellow):

linux live

Use the mouse or keyboard to select your USB stick and you should – if all went well – see a black screen that says the following:

linux live

Eventually you will see the logo of your Linux distro, followed by the desktop itself. You’re in!

mac-boot-linux-running

Congratulate yourself – you got Linux to boot from USB on your Mac, and that means you’re awesome.

Want to actually install Linux on your Mac? That’s another can of worms entirely – and probably one I’ll touch on in a future article. For now feel free to check out the Mac dual boot guide at help.ubuntu.com for in-depth instructions.

Optional: Manually Switching Distros

When you explored your USB stick with the finder, you probably noticed only three two files were added by Mac Linux USB: “boot.iso” and a boot loader ending with 32 or 64 (depending on whether you were attempting to boot a 32 or 64 bit operating system).

linux live usb

If you want to switch distros don’t feel like you need to use the GUI tool to do so – you can simply rename your new ISO to “boot.iso” and replace it. I did so to switch my drive from Ubuntu to Linux Mint without issue, but note that there’s no reason to assume every ISO under the sun will work – it seems to primarily work with Ubuntu derivatives.

If you want to get even more hands on, check out this amazing guide, from Studyblast.com. It includes a link to the EFI files used to cause the ISOs to boot, allowing you to create your own disk without the need for software like Mac Linux USB loader. Feel free to use this if you find the process simpler without software.

SevenBits, the developer of Mac Linux USB Loader, is quite actively developing the software – and will likely keep it working with future versions of Ubuntu, and possibly other versions of Linux. That’s why it’s my recommended method. Up to you, though – whatever works best.

Conclusion

Finding this process took me a while – I manually created quite a few drives only to find they didn’t work. I’m very thankful I eventually found Mac Linux USB Loader, because it removes a lot of the guesswork from the process. Hopefully every Mac user wanting to boot Linux from USB will find this software.

Of course, if you’re stuck, you can also ask for help in the comments below. I’ll do what I can to point you in the correct direction, but I might not be able to help – it really feels like Apple made life needlessly complex for us would-be Linux users.

What do you think? Is this process harder than it needs to be? Did you get it working some other way? Let us know in the comments below.

    Thanks a lot for your article! It has great contents!
    I have a problem with my dual boot installation. I'm trying to install Ubuntu in my Mac with an USB, and when clicking in the Ubuntu installer, it does not recognize the Mac OS, but I want to maintain it. There are only two options: to delete all the other OS or "Other option", instead of "Installing Ubuntu alongside MacOS".
    Do you know what the problem is? Can you help me?

    Has the Mac Linux USB loader been updated since 2015? I don't see any updates in the last 18 months or so. I'd like to use just part of an external SSD hooked to my MBP (mid-2015 model) to run Ubuntu 16.04 from. Will it support the latest versions?
    Thanks!

    Hi Justin,

    I’m the author of Mac Linux USB Loader. The application is now at version 3.3. Its user interface has been totally re-designed since this article was posted and it has new features too! I recommend that everyone try it out: https://www.sevenbits.io/mlul/

    Hi, thanks for the article. THough I came in quite late in doing this, it works ok. My question pertains to downloading drivers on my Macbook Pro. Everytime I would log out, and would again log in using Linux, my wifi cannot be detected, and I still have to download the drivers again thru the net. IS there a way to wake the need to download disappear, and save the drivers, so that next time I wanna use Linux, don't have to download anything anymore.. Thanks

      October 9, 2016 at 4:24 pm

      If you’re setting up Ubuntu on your USB, you can use persistence to save drivers (for wireless, etc.) between runs. Mac Linux USB Loader can set it up for you.

    Thanks for the article. Really helpful. But I was wondering how to make it so that my mac always starts up with OSX, but I can use Linux if I just press the option key when it starts up. In other words, how do you get rid of that screen on startup that asks what you want to boot with?

      When you reach the boot volume selection screen, hold down the Control key before hitting Return. On most Macs that should turn the arrow into a circular arrow, indicating that the selected volume will be automatically booted from thereafter.

  11. Eric Knibbe
    January 25, 2016 at 3:18 pm

    Hi Justin, good to see you still writing. Thought I'd point out that the name of the boot loader depends on the architecture of the EFI rather than the operating system. So, bootX64.efi will only work on Macs with 64-bit EFI (2008 & later), earlier Macs would require bootIA32.efi.

    • Justin Pot
      January 25, 2016 at 3:26 pm

      Good point, though are there many (or any?) 32-bit Macs?

      • Eric Knibbe
        January 25, 2016 at 5:39 pm

        Intel Macs from early to mid 2006 have 32-bit EFI with a 32-bit-only Core Duo CPU and are stuck at OS X Snow Leopard, while Macs from late 2006 to mid 2007 have 32-bit EFI and a 64-bit Core 2 Duo, and so are stuck at OS X Lion. Macs since then which officially support Mountain Lion and later have 64-bit EFI. It's worth pointing out since models that have fallen off of the support wagon are more likely to get the Linux treatment.

    Why the hell must apple f*** someone so hard? Why isn't it possible to just create a regular bootable usb drive, boot of it and install a damn distro? Honestly I don't get it. Hell I wouldn't even complain if I actually bought one, but my girlfriend has one and honestly, I think mac os sucks just to bad to get used to. So I've installed a couple of month ago windows via boot camp ( still don't get the sense of that) because she play wanted to play some games. Unfortunately she doesn't like windows (just like me...) for regular use. Ok to be honest I'd prefer windows over mac but that's another topic. So I wanted to install a nice easy Linux distro additionally. Why? Because Linux just runs. And I'm quite shure it's way faster as macos (which is on her Macbook painfully slow). Hell even windows manages to run faster and with more performance. And now I'm reading stuff and watching how in the sake of satan I'm supposed to install a God damn Linux distro additionally. Why the hell must apple make this process hard and annoying? On every damned regular pc it's easy as pie. I'm sick of apple. I'd never ever buy apple PCs (and yes an apple computer is nothing more than a damn PC) after facing all this crap when using my girlfriends laptop.

      I've run into complications installing Linux on many computers, but it's true that Macs are more complex than most. I recommend you stick to your own computer and leave your girlfriend's Mac alone.

    Hi,

    Problem: Kali boots fine, however when I view my drive on Kali, it only has about 970 MB for disk storage even though my USB drive has nearly 60 GB of free space. I cannot update Kali or do anything that takes up storage because of this.

    Info: I am running Kali Linux on my MacBook Air using Mac Linux USB Loader. I have formatted the USB drive to FAT and set up persistence (which isn't working either). Kali is bootable but only able to use 970 MB of storage. I am hoping to have the OS recognize the USB drive so I can save files and update Kali. Please help!

    Thank you.

    So.. You guys are awesome! :) I've been looking for a way to run Kali Linux on my Mac for a while. My first attempt was at dual booting which resulted in me mucking about in terminal, following the instructions on the Kali website, following those instructions precisely, only to have a different response in terminal than the one outlined on the Kali website. Which ultimately resulted in a lot of wasted time and effort. Fast forward to now.. and here I am witnessing a beautiful sight to behold. Kali Linux running perfectly on my Mac computer. The screen I'm looking at right now is something I've wanted to see for a long time. And I would not have been able to were it not for this article and the wonderful software Mac Linux USB Loader. I think this process was actually even easier than the last OS X update I installed. So a very sincere thank you to both the software developer and to the author of this article for making a complicated process so incredibly easy. Cheers!!

      I'm just some guy who wrote about this, and am not behind the software in any way – I don't think logs will help me very much. You could let the developer know what's up, but if you're getting that far into the process I'm fairly certain the problem is with Ubuntu itself. Your hardware isn't yet supported by the OS, would be my guess.

      It's astounding how complex getting Linux onto a Mac is. It never used to be this bad, but drivers were always an issue with brand new ones.

      Thanks, as you can tell I'm more at home with android. Next question is bit more of a difficult one, how do I make it persistent from USB?

      Ya thought it be a bit of pain alright, trying to make it for the brother. Only starting messing with linux last week and have puppy running from usb like a charm and got mint running alongside my win7 without having to format the harddridve, then i hit the wall that is Apple. Thanks for you help, keep me up to date.

    JK read the first comment; step one is a must if your USB has been windows-formatted in the past. Don't skip it; spay and neuter that USB drive.

    • Justin P
      October 22, 2013 at 5:21 pm

      Yeah, skipping that step can cause exactly the problem you had, and pet neutering is important if we want to maintain a balanced ecosystem free of stray cats and dogs.

    Trying to boot BackTrack 5 R3 from an 8g usb using this program on a MacBook Pro (2011 I believe), the process hangs on "OK, fasten your seatbelts..."
    I let it sit there for about 15 minutes before I assumed it wasn't going anywhere and had to hard-power-off the laptop.

    How long does the boot generally take from the seatbelt message?

    A complete nubee question - would a USB DVD be a work around? If you got the -mac edition? I have a iMac with a dvd , and booted Ubuntu to it, but I never noticed the -Mac in the name...

    • Justin P
      October 12, 2013 at 6:45 pm

      If you have Apple's USB DVD drive booting from it should not be a problem. Older Macs may not need the Mac-specific ISO, either.

    Hey Justin/SevenBits
    Firstly thank you for all your respective time and effort.
    - greatly appreciated.
    Attempting to create a ubuntu USB install on the following system:
    Model Name: MacBook Pro
    Model Identifier: MacBookPro5,4
    Processor Name: Intel Core 2 Duo
    Processor Speed: 2.53 GHz
    Boot ROM Version: MBP53.00AC.B03
    SMC Version (system): 1.49f2
    Memory 4 GB 1067 MHz DDR3
    Graphics NVIDIA GeForce 9400M 256 MB
    OS: OS/X 10.8.5 (Mountain Lion)

    USB: SanDisk 32GB 2.0
    Mac Linux USB Loader v1.1

    Followed the excellent instructions provided by Justin, "exactly".
    - Clean erase/partition/format of USB -used (ubuntu-13.04-desktop-amd64+mac.iso)
    - Create Live USB: result no GUI was loaded only CLI.
    Dropped into bash environment, not being a Unix guru, i decided to try alternate *.iso's...
    After repeated try's only got past the dreaded "fasten you seat belts" once, the first time all subsequent attempts froze at the the "fasten seat belts phase" .
    ( Attempts were via the Mac Linux USB loader app - download distribution icon)

    Thus given my system, is it the recommendation to acquire a "PC" and install Ubuntu that 'just works?" or have I missed something obvious...
    - apologies for the long post, appreciate you taking the time reading this,
    any and all advice appreciated and welcome.

    ps. like (most) others have searched extensively on alternate methods and sunk a lot of time on what I would have hoped to be a rather straightforward procedure. :-)
    pps: me suspects I have the *wrong* macbook pro :/
    Cheers !

      September 16, 2013 at 8:48 pm

      I'm not sure what could be causing the hangup in your case. Have you verified that an actual CD will boot? I know it sucks, but it might help us know if this is an Ubuntu problem or a USB-boot problem...

    September 11, 2013 at 7:15 am

    Thanks. If *you* have tried and haven't succeeded, it ain't gonna be easy as 1-2-3 ;-)
    I'll put this on hold for a while. Is there a way to get notifications, or subscribe to this article? One more note. Replacing the optical drive with a HD/SSD, would that allow me to boot (Linux) from it?

    • Justin P
      September 11, 2013 at 6:08 pm

      I'm just a guy who enjoys writing about technology, I'm sure if you gave it a shot you could figure out how to do this just as quickly as me.

      You can boot Linux from a second drive on your Mac, sure, and also from a partition on your primary Mac drive. I installed to a partition, myself.

    • SevenBits
      September 11, 2013 at 7:15 pm

      I'm afraid that persistence really hasn't been messed around too much on Linux when booting in UEFI mode. The steps are as easy as 1, 2, 3 - assuming you don't have extra needs, of course.

      You can boot Linux from an SSD, as Justin said, and you can install to a partition, and choose whether to want to boot with BIOS mode or UEFI.. I, however, would leave the optical drive in place so that you can boot Linux distributions that don't work with Mac Linux USB Loader.

    Great read.
    What are my options to boot into a (persistent) Linux on a 2011 13" MBP?
    I have a Bootcamp setup at the moment that I cannot afford to lose, w/ virtualized Debian.

    SD card seems to be disfunctional on recent models, and this article is about live Linux.

    I'm thinking (internal) optibay, (external) TB, FW, ...
    Your suggestions for working (and proven) setups highly appreciated.

    • Justin P
      September 10, 2013 at 3:32 pm

      I've yet to get a persistent install to work on an external drive, and I've tried. So I'm afraid I can't help right now, but expect an article on this site as soon as I get it working.

    September 9, 2013 at 12:31 pm

    Fail. I could not go past step 1 because what I see on my screen doesn't match the screen here in this tutorial. See the screen in step 1 that has buttons for "First Aid", "Erase" and "Partition"? My buttons differ; I don't have "Partition". Please help as I'm about to return my MacBookPro. Oh, it's running Mountain Lion.

    • Justin P
      September 9, 2013 at 2:45 pm

      You need to click the drive you want to partition before those buttons will come up, if I'm understanding correctly.

    Hi ! Very nice GUI app
    In few steps can be dual bootable and installable this way :
    Resize your mac partition and leave free space for linux using diskutils( select your hardrive in diskutils and click on partiton and resize with the mouse.

    install refit : http://refit.sourceforge.net/doc/c1s1_install.html and then just simply after having plug the usb stick :
    $ diskutil list
    $ diskutil unmountDisk /dev/diskX (disk number that is the usb stick)
    sudo dd if=/Users/username/Downloads/linuxlivecd.iso of=/dev/rdiskX bs=1m

    reboot press ALT and choose your usb for an install of linux

      I see this thread is 17 months old, but the above procedure posted by maxou worked for my old 2006 Pro 1,1 a few weeks ago. I had to download a package called "macfancltd" to get my cpu fans up to speed. Linux out of th box (Mint) doesn't govern fan speed, and overheating can become an issue.

    August 19, 2013 at 4:26 pm

    A small inaccuracy:
    "Note that Macs cannot boot from the SD card reader"

    This general statement seems not correct. I've just copied (using dd) a converted ubuntu-12.04.2-desktop-amd64.iso to a SD memory card, and it is well booting on MacBookPro5,5 (Mid 2009) from SD card slot.

    And you can also install Mac OS X on an SD storage device and use it as a startup volume.

    • Justin Pot
      August 19, 2013 at 8:47 pm

      So weird – I tested mine several times and even looked this up. Perhaps it's just with newer Macs? Or perhaps I messed up? Maybe someone else knows something.

    • Stratomat
      August 23, 2013 at 7:10 pm

      I just tried booting Ubuntu (above version) on Macmini6,1 (Late 2012) from SD card slot and it doesn't work. Booting from the same SD card using an USB card reader actually works well.

      So you're right, it affects only newer newer Macs.

      August 8, 2013 at 11:26 pm

      It's basically a live CD on a USB disk – not a persistent install.

    Been trying to use this software with a 500GB Seagate drive but the loader does not see this hard drive at the Make Live USB screen. I tested it with a 1GB thumb drive which was recognized with no problem. Perhaps the program cannot handle a large external HD? Any guidance?

    • Justin Pot
      August 3, 2013 at 3:30 am

      No idea why a large drive wouldn't boot. Did you reformat the drive? Flash drives are probably a better idea in any case...

  55. Dean
    August 2, 2013 at 9:16 pm

    This is great! Very very cool, and exactly what I needed to find after 4 or 5 hours of trawling the internet and formatting my USB umpteen zillion times for various ways to get around the efi problem. Nice easy, logically laid out, I like it!

    The catch for me is that I'm running 10.6.8 and so miss out, just ;-) is there a mailing list or something I can subscribe to in case it becomes backwards-compatible? I'd really love to get a good version of linux up and running on my Mac, and Mint looks soooo good :-( *tear* ;-)

    That said, keep up the good work!!!

      Hello Dean,

      Sorry, there's no mailing list. I am considering a solution for you guys running older OS X releases, as I have received numerous requests about this. However, a full port is unlikely to occur unless a generous Internet user wants to oblige.

      Are you sure that you can't upgrade to at least Lion? Lion is 100% supported.

    Hi Justin,
    Thanks for the article. I was trying to create usb for Kali-Linux. -I tried using Linux Mint and Win 7 but neither was recognized by Mac OS 10.8

    Does Kali Linux have or need a Mac Distro?

    • Adam
      August 9, 2013 at 10:36 pm

      It doesn't:/ Also I wouldn't recommend using Kali on Mac hardware unless you have an external wireless interface (ie: usb, pci, etc.) because the Broadcom cards don't have monitor support currently, or even an open source module in the kernel for that matter.

  57. Brian
    July 29, 2013 at 10:31 am

    I cannot get this to work. I beleave i have correctly follwed the instructions, but the computer just does not see the USB stick as a start up disk, I am trying to boot a 64 bit Intel Core 2 duo Mac Mini. The USB stick has been formated to MS-DOS (FAT32)2 and i have tried with several versions of linux including two downloaded with the app.

    • Justin Pot
      July 29, 2013 at 2:25 pm

      Brian,

      That's too bad. Is your drive connected directly, or through a USB hub of some sort? Just ideas, assuming you've read most everything above...

  58. Troy
    July 27, 2013 at 1:05 pm

    It worked!

    I have been playing around with linux live usb on a mac for a while, with little joy. I found another app called 'Linux USB Builer' but I couldn't get it to work on Mountain Lion.

    So far I have tried Ubuntu and Mint. Main issue I have so far is that they only work with ethernet and not the wireless connection.

    Thanks for the tutorial Justin! It was very clear. And thanks to SevenBits for the code. I am going to have a look now at their github page and follow this app's progress.

    • SevenBits
      July 27, 2013 at 5:15 pm

      Glad it worked for you, Troy! Always happy to make tools that help people.

      WiFi is always an issue when running Linux on Apple hardware. You'll need to install non-free drivers to get it working (hint: the wireless cards are largely Broadcom devices).

      I hope you continue to use Mac Linux USB Loader - a plethora of new features are planned for future releases!

    July 20, 2013 at 4:47 pm

    Unfortunately I can’t seem to get this to work. Followed the steps to the letter and it just hangs on the black “fasten your seat belts” screen.

    I have a 64bit capable Mac, downloaded the Mac version of Ubuntu from the USB loader app, have a properly formatted USB thumb drive (San Disk Cruzer Glide 32GB) but Fail for me.

    One note: your instructions say “When it’s done you’ll see there are only two new folders and three new files on your drive.” but I only see two folders and TWO files, not Three. Was this a typo or is there supposed to be three files? (your screen shot only shows two as well.)

    Any further help greatly appreciated!

          The only thing I can think of is that that drive is massive, but I don't think it should make a difference. What version of OS X are you using? Could be your Mac is old enough that our software isn't necessary, and software like UNetBootin will do the job.

        • Nick V
          July 22, 2013 at 10:59 pm

          Mac 10.8.4. Just thought this would be the easiest way to do it. Everything seems to install fine on the thumb drive, I even tried the "blessed" version of the USB loader, but the Macbook Pro just won't boot from it... baffled.

    • Justin Pot
      July 16, 2013 at 10:52 pm

      Which version of Linux are you trying to boot? I was only able to get this working with the (Mac) version of Ubuntu, which the app provides automatically...and the Fedora version offered by the program.

      • Kyle
        July 16, 2013 at 11:26 pm

        Thank you for such a quick response. I am using the one provided by the Ubuntu website because I was unaware that there was a mac-specific version offered by this program. If you don't mind me asking, how does this version differ from the one offered by the official website?

        P.S. I am downloading the Mac one as I type this.

        • Kyle
          July 16, 2013 at 11:58 pm

          It works now, but I am still curious about what's different about this version.

        • Justin Pot
          July 17, 2013 at 1:13 am

          From what I understand the difference is superficial, but the Ubuntu team needed to make a minor change or Macs would not boot. I believe all reference to the bios is removed...

          Did some searching, there's a decent answer here halfway down: http://askubuntu.com/questions/37999/what-is-different-about-the-mac-iso-image

    July 14, 2013 at 1:53 pm

    • Justin Pot
      July 14, 2013 at 3:06 pm

      Exactly the same with me. I'm running os x 10.7.5 on a 2.66GHz Core i7 (only dual core I believe). 4GB ram.

      I tried the Linux Mint 15. Will now try the ubuntu for Mac. tbh all I want is somewhere I can format my external HDD to back up my linkstation!

    • Ziggy
      December 8, 2013 at 5:56 pm

      Right so the ubuntu did the same. I was using an 8GB stick so tried with a 1GB one and different errors:

      With ubuntu it would actually launch into the OS, but the display is all wrong - i could just about make out the 'ubuntu' with the dots counting up to launch. But once it launched it was all scrambled. Could only make out loads of pixels moving around when I moved the mouse, but couldn't do anything useful.

      With the linux mint 15 - same result as using 8GB stick. I think the issue is the display...
