How to Create a Bootable USB Drive from Your Windows CD

Do you have a Windows CD or DVD, but can’t use your optical drive to install the operating system (OS) on your new computer? Or maybe you’re concerned about CD/DVD rot and just want to create a backup.

Instead of a disc, you can use a USB drive to install Windows. Flash drives are smaller, have more storage, and can be used to install multiple OSs — if you use the right technology.

Here is how to create a bootable USB drive How to Create Windows 10 Installation Media How to Create Windows 10 Installation Media Regardless of how you arrived at Windows 10, there's a way to create your own installation media. Sooner or later you might need it. Let us show you how to be prepared. Read More , instead of using a Windows CD.

Benefits of a USB Drive

There are several situations where USB drive installation media is beneficial:

  • You can easily create backup installation media.
  • Significantly faster installation rate vs regular installation media.
  • Keep original installation media in pristine condition.
  • Easy to carry multiple operating systems on a single USB drive.

Our relationship with Windows CDs and DVDs has changed, too. For instance, Windows 10 is available for sale on a USB drive. Discs are still available but are no longer the only method of installation. Furthermore, newly purchased hardware usually comes with an OS pre-installed. Consequently, some users never actually use or even see installation media.

Copying Your Disc with WinToFlash

USB drives are all very well and good, but you still need a copy of your Windows installation disc. In the past, it involved manually copying files, opening the process up to mistakes. However, we can easily automate that process using WinToFlash.

WinToFlash is great for making a bootable USB from your physical installation media. But in this day and age, many users eschew the traditional and head straight to the internet, keeping it digital.

The Microsoft Media Creation Tool has made the process of downloading Windows ISOs that much easier. Accordingly, the Media Creation Tool automatically downloads an ISO to your specification, eliminating the need for copying physical media to your computer, then onto your USB drive.

Windows 10

Download and run the Media Creation Tool. Accept the licensing agreement. Select Create installation media for another PC.

This can be installed to a USB drive using alternative software, such as Rufus. In this instance, select USB flash drive, then Next. Now, choose your USB drive and create the installation media.

Windows 7/8.1

A Quick Rufus Tutorial

Next, select the small disc icon and browse to the Windows ISO you would like to create installation media for. Set a new volume label if you desire, but it isn’t necessary. Select Start, and let Rufus take care of business.

Can I Boot From USB?

This is a very common question. It is largely system specific but can be altered by the user via the BIOS. This is controlled by the boot sequence.

Your system will usually seek to boot from wherever your OS is installed. The drive containing your main OS will be the first option in the boot sequence. It is possible to manually override this, instead of booting from a USB drive containing new installation media.

BIOS configurations are different for each manufacturer. I would suggest searching the internet for “[hardware manufacturer] BIOS tutorial/boot sequence.”

    It still doesn't answer the question: "How do I create a bootable USB from bootable DVD?" I don't have an iso file. I only have a DVD with a bunch of files and folders there.

    Wintoflash free version doesn't offer even the very basic functionality now. Are there any other options? Again, for converting bootable dvd to bootable usb, not Windows iso to usb.

    Terrible article. Unfortunately, WinToFlash only allows you to make a multiboot USB with 2 entries when using a personal/non commercial license. Utterly useless and a cheap trick on their part. On the other hand, it is your responsibility to research the programs you present more thoroughly...
    MUO used to be a place to learn new programs and features...too bad this is not the case anymore...

      I don't think that makes it a "terrible article" -- it is just an oversight on my behalf. But you're right, I should have picked up on that before posting. MUO is still very much a place to learn new programs and features, as there are thousands of other articles, even on this very topic.

      My apologies for the poor research. I was updating a much older article and used the program the original author had compiled the article around. If you'd like to create a multiboot USB, here is a fresh piece on the same topic I wrote in February:


      Again, my apologies.

        I do believe you should be more careful when providing info about programs and when you fail to do that, then the article is indeed terrible.
        I am not a troll though and I do appreciate your courage to admit your mistake. In addition, your related article in February was excellent and very helpful. Please build on that and not this :)

    Hi! I tried to make my USB flash bootable in order to install WinXP. WinToFlash made my flash bootable but it does not install XP. When I boot from the USB the cursor just blinks and stays there for ever. The installation process does not begin. Any ideas? Please....

    (long time user of these forum sites, first time commentor.)
    normally when i have an issue i perform a search to scour online forums for people who have had a similar issue and to read possible solutions. this method has worked about 99% of the time. however, after spending all day (literally, all day) yesterday trying to get not only xp onto my usb drive but make it bootable in the process, this site really became the salvation to my sanity (and what's left of my hair).
    that said, i think it is important that others realize that if the copy of xp they have is only sp1, they will need to integrate sp2 into it in order for the usb drive to work properly. the following site helped me to do just that:
    and this website provided me with the tools to make my usb drive bootable. so thanx Varun!
    what strikes me as "odd", is that while every one of these tutorial sites i came across usually begin with some iteration of the fact floppy drives are dead, and some computers either have a non-working optical drive or no optical drive at all, and so booting off a usb drive will become a necessity. that there is so many "possible" solutions to do this. and that the majority of them are crap. i mean, sure, from one of the tutorial sites i was able to make my usb drive bootable, but it was impossible to install xp since it was in a FAT16 environment.
    maybe there should be an option inside windows itself to format a usb drive and make it bootable (much like in win98 there was an option to format a floppy disk and make it bootable...), i don't know, something easier than spending a whole day trying different solutions, and honestly contemplating purchasing an external optical drive to get the installation done. ugh!
    and thanx again Varun!!!

    I think theoretically, the transfer speeds should be better and the installation process is a little faster.

    As a novice, I went through the process of trying to make a bootable USB from this process. Process was easy to follow and it completed with no problems. Changed the BIOS to boot from a USB as 1st selection. Did a shutdown and power up. Other than the USB blinking a few times it would not boot up. Cursor stock in upper left corner blinking. Must of done something wrong. Used Boot CD that came with the Dell XPS M1330 (Vista Ultimate)

    Hi Varun am impressed by your work.
    Actually previously I have less knowledge about bootable USB and after your post it seems helpful.
    Anyways thanks for the brilliant post.

    Installs from a USB drive are SIGNIFICANTLY faster than from a disc. I've done Vista and 7 installs from a USB drive that took about 15 minutes.

    As far as the size, for Vista or Win 7 you will need a 4 Gig drive. Considering you can buy a 4 Gig flash drive for $10 why bother with anything less?

    You actually don't even need to go to all the trouble in the article. Just copy all the files from your DVD or from the ISO file to the root of a freshly formated USB drive and you're ready to go.

    what is the smallest drive size I can use?

  19. Chris W
    September 10, 2009 at 6:22 pm Considering the CD you usually install an OS from is around 700mb, a USB stick of the same size should do. Even if you slipstream SP3 onto the stick it will only be around 600mb. You can slim it down even further with a product like nLite.
