Here’s how to fix a Windows 10 boot loop and get your PC or laptop up and running in minutes.

What Is an Infinite Boot Loop?

Windows 10 isn’t particularly prone to an endless boot loop, but it isn’t unheard of.

It’s easy to spot, specifically by the failure of Windows to correctly load up after switching on your computer. Instead, the computer will fail to reach the logon screen before resetting to the boot screen and attempt to reload Windows. The is now caught in an infinite loop of booting and crashing.

The error occurs because of a problem with the Windows system registry. Unfortunately, without booting into Windows the registry cannot be fixed, leaving the operating system unreachable. It’s a Catch-22 situation.

In order to overcome this problem, use Windows 10 recovery options.

What Causes a Windows 10 Boot Loop?

A Windows 10 reboot loop can be frustrating to deal with. But what causes it? Typically, the fault can be traced to one of three things:

  1. A Windows Update
  2. An updated or new Windows driver
  3. The installation of new software (an app or game)

Something in the process goes awry. The result is a computer that is caught in an infinite reboot loop.

This is a problem that has plagued Windows for years. Further down the page, we have some tips for fixing boot loops in Windows 7 and Windows 8. If you’re using Windows 10, however, the fixes you’re looking for are in the next section.

When Automatic Repair Fixes the Windows 10 Boot Loop

If you’re lucky, the Repair Windows or Automatic Repair features might kick in without any prompting from you. Typically, this will only happen after several reboots, so give your computer time to get to this stage. Some manual interaction may be required—use the Automatic Repair option here and follow any steps.

However, if this hasn’t happened within 15 minutes, it’s probably not going to. Time to take matters into your own hands.

Access Safe Mode to Fix Windows 10 Endless Boot Loops

Three more options are available to fix an endless boot loop in Windows 10:

  • Safe Mode: this lets you access the operating system and uninstall any software, drivers, or Windows Update causing the fault
  • System Restore: a fast way of undoing recent changes
  • Reinstall Windows 10: the nuclear option, for use when nothing else works or you don’t mind losing data.

Accessing Safe Mode will depend on how the boot loop is presenting, as well as your system setup.

1. Dual Boot Windows System

If you have multiple versions of Windows installed on your computer, wait for the OS selection screen to appear. When given the choice, instead of selecting Windows 10, choose Change defaults or choose other options. Then follow the steps above to access Safe Mode.

2. Manually Access Safe Mode

In some cases, you’ll be able to access Safe Mode from within Windows 10. This will be possible if the reboot loop is triggered on the launch of a specific app or hardware connected.

Before the reboot is triggered, you have three options to reboot Windows 10 in Safe Mode:

  • Hold Shift then Start > Restart to boot Windows 10 into Advanced startup options.
  • You might also open Settings (press WIN + I) then Update & Security > Recovery > Advanced startup > Restart now.
  • In an elevated Command Prompt (search cmd in the Start menu, then right-click and select Run as administrator) enter shutdown /r /o to reboot the computer into the Advanced Boot options.

As noted, you may not have long to input your command. The first option is probably the quickest.

3. Use Installation Media to Access Safe Mode

Windows 10 users should have a recovery partition on their PC’s hard disk drive. If not, a USB or DVD recovery drive can be made by downloading the Windows 10 installation media. Note that this will need to be created with a different computer.

With Windows 10 stuck in the reboot loop, all you need to do is insert the installation media. Alternatively, access the UEFI/BIOS (tap Del, F8, or F1 when the system boots) and find the boot manager.

Select the recovery partition as the primary device then restart the computer. See our guide to creating Windows 10 installation media for more details.

Both methods should guide you through the Automatic Repair tool, or give you access to the Advanced options screen.

Fix Infinite Boot Loop in Windows 10 Safe Mode

With the computer in Safe Mode you can take steps to prevent further boot loops. This could be anything from uninstalling drivers to uninstalling Windows Updates in the Command Prompt.

Solve a Windows Update-Based Boot Loop

In Command Prompt (which you should open as Administrator on the desktop) enter

net stop wuauserv

Follow this with

net stop bits

Wait for the response, then browse to C:\Windows\SoftwareDistribution. Here, delete all the directory contents. If you’re using the Command Prompt, use our Windows command line guide for help using RD (remove directory).

(If you can only access the Advanced options screen, use the Command Prompt. This is also an option in Safe Mode.)

When you restart Windows 10, it should boot as normal.

Did an App or Game Cause a Boot Loop in Windows 10?

Suspect the boot loop is due to the installation of an app (perhaps one that launches at start up)? Perhaps it was a game you recently installed. Either way, this can be resolved by uninstalling the software.

Simply find the software in the Start menu, right-click, and choose Uninstall.

Uninstall problematic apps in Safe Mode

When you restart Windows 10, the boot loop should be fixed.

Stop Hardware Driver Boot Loops

If the system is in a boot loop due to hardware drivers, this can also be solved in Safe Mode.

Right-click Start and select Device Manager. Here, search for the suspect device. Typically, this will be something you’ve recently added, although not always. Right-click the device, select Properties > Drivers and choose Roll Back Driver.

If this doesn’t work, disable, and uninstall the driver. With the device selected, right-click and choose Disable Device, then Uninstall Driver.

Uninstall device drivers to fix Windows 10 reboot loop

You can then restart Windows 10.

Restore or Reinstall Windows 10 to Fix the Infinite Boot Loop

If you cannot access Safe Mode, or the fixes don’t work, the best solution is to use the refresh option. You might also reset Windows 10 back to the factory settings.

Check our detailed guide on resetting and restoring Windows 10 How to Factory Reset Windows 10 or Use System Restore How to Factory Reset Windows 10 or Use System Restore Learn how System Restore and Factory Reset can help you survive any Windows 10 disasters and recover your system. Read More for more on this.

This process essentially reinstalls Windows 10 for you, leaving you with a blank slate. Just remember to back up your personal data first!

Fix Boot Loop Problems in Windows 8

Fixing a boot loop in Windows 8 and 8.1 is not dissimilar to Windows 10. Check the following video for the steps.

The real difference here is that Windows should boot to the Automatic Repair screen if there is a problem. Here you can access the Advanced Options menu, which may not be available in the boot loop conditions. As such, you’ll need to find the Startup Options as described and select Enable Safe Mode.

Recovering an Infinite Boot Loop in Windows 7

It isn’t only Windows 10 that can be stuck with an infinite reboot loop. If you’re using an older version, use these tips to overcome the reboot loop and get your system back online.

To fix the boot loop problem in Windows 7, you should have the installation media. If you don’t have the original DVD, grab the Windows 7 media installer tool from Microsoft.

You Fixed Your Windows Boot Loop!

Reboot loops have long been a problem with Windows. While previous versions offered a couple of ways out in the recovery options, these solutions were far from comprehensive. Thankfully, Windows 10 has great recovery and restore tools, which make a boot loop problem easy to deal with.

When following the steps outlined here, please take care to follow them precisely. Errors that you make while using the command line interface cannot be undone.

If you have been lucky enough to recover from the Windows 10 infinite reboot loop, it’s time to take precautions. Check our Windows 10 data backup guide The Ultimate Windows 10 Data Backup Guide The Ultimate Windows 10 Data Backup Guide We've summarized every backup, restore, recovery, and repair option we could find on Windows 10.

    This worked really well. Something else happened and I'm not sure what, I left my office and came back and it was constantly restarting again. I tried to repeat this fix, and now it won't even load the repair screen! It restarts automatically no matter what startup option is selected from the F8 screen.

    January 10, 2017 at 10:56 pm

    Thanks so much for this, it worked when nothing else I was trying was! Fully back up and running after a scary infinite 'Automatic Repair Loop'.

    One thing to note, your drive letters may not be what you expect when in command prompt, so don't dispair if your C: drive doesn't list your system files. Try all your available drives. My system drive ended up being G: for some reason.

    THANK YOU!

      what do you see instead?

      have you tried cd back to the C: first?
      C: DIR is not a command, and it's not one I've suggested in this post. But without a screen grab or cut and paste of what you've done, I can't really help :)

    I followed all of the steps you have provided, but once it is mentioned in your post "if any of these files display a size of zero bytes, you will have to use another method", I found a couple files with zero bytes. Whst is the alternative method for the loop fix at this point?

    My problem is that I will start up my computer and see see [enter password] in a white box. It didn't do that in the beginning after I pressed a button, and I don't remember what button it was, and then it shows the Toshina start up screen and ask for my HDD/SSD and I put it in and repeat. I tried a bunch of things like Shift+R but still doesn't stop the cycle. Help?

    DEFAULT, SAM, SECURITY, SOFTWARE, SYSTEM all show up with 0 bytes.

    What is this other "method of restoring Windows 7"?

    Can I copy DEFAULT, SAM, SECURITY, SOFTWARE, SYSTEM from another computer with Windows 7?

    • Alan R.
      July 6, 2016 at 4:57 am

      UPDATE: I copied the DEFAULT, SAM, SECURITY, SOFTWARE, SYSTEM from another computer, restarted, and it STILL loops infinitely!

      I previously already did a FULL reinstall of Windows 7, which also formatted the HDD, so this should run as if it is fresh out the box. It doesn't. It just loops.

      The laptop (Toshiba Satellite L655-S5161x) is old, slow, and has essentially been replaced already, and ALL of my important files were manually removed using CMD prior to the reinstall... but that's not the point! The point is to get this thing to work!

      Hi, can you recall how the problem started?

  50. Regina Mize
    December 29, 2015 at 12:44 am

    I am on an Alienware I-7 machine with Windows 7 and am stuck in an update failure loop with the message, "failure configuring windows updates, reverting changes, do not turn computer off" for 24 hours now. I finally tried rebooting, but it just goes back into the same loop unless I tap F8 upon restart, then I can get to the Safe Mode Screen.

    I am in safe mode with networking now and followed the instructions above but when I try to use the 'copy *.*' command I get the message that all 5 folders (SAM, SECURITY, DEFAULT, SOFTWARE, & SYSTEM) are in use by another process. So I can't continue. Any ideas why I am getting this message and what I need to do next?

    Just FYI, I also tried to repair my computer from the Startup Repair prompt but it said it could find no problems. Then I tried to do a System Restore. There were three restore point dates, but the restore failed on all of them. I also tried resetting my computer to the last known good configuration but that did not work either.

    I am now at a total loss and am wondering if I need to just restore the computer to factory settings. I don't have a disc drive, but there is an Alienspawn Restore option under the system recovery menu.

      January 22, 2016 at 2:33 am

      You have to boot in start up repair. Not in safe mode.

      • Regina Mize
        January 22, 2016 at 5:37 pm

        Thanks for the reply, but You must have missed where I stated that I already tried to boot up in start up repair and that didn't work.

        Since my comment was over a month ago, I did eventually find a solution. Here is what I finally had to do after all other attempts to repair and restore failed, and after spending 4 hours on the phone with Microsoft tech support.

        First, since my Alienware laptop has no CD/DVD drive, I had to get on another computer and download the operating system onto a blank flash drive. This took almost an hour. Then I had to go into the advanced boot drive screen in System BIOS (how you access this is different depending on your computer, but on my system you hit repeatedly upon powering up) and change the boot option to external drive. Then you save and exit and turn off the system. Next you put in the USB flash drive and restart. This allows the computer to boot up from the USB drive, bypass the failure loop, and reinstall the operating system. However, this does completely wipe your computer to factory settings and does require that all software be reinstalled.

        I ended up installing Windows 10 and have not had any problems since. Hope this helps someone else who is having the same issue where start up repair and system restore does not work.

        • Regina Mize
          January 22, 2016 at 5:40 pm

          The key you hit repeatedly to get into BIOS on my system was F2.

        • Regina Mize
          January 22, 2016 at 5:43 pm

          I also forgot to mention that after the new operating system is installed you have to rremove the USB drive, and restart the computer and go back into the System BIOS and change the boot drive back to what it was before. Then again save and exit and restart.

    Couldn't find the various folders in the C: Drive, found them in the F: Drive though, and when I copied them over and checked the DIR they all had 0 bytes. Have tried reinstalling windows but when restarting the reboot loop continues.

    for Rinaldo. Look in your installed updates and uninstall the Windows WAT update KB971033 is you see it. Paste the KB # into the search bar and if you see it, uninstall it. This causes the fake Windows not genuine error. MSFT got sneaky and tries to always offer it with automatic update. You don't want it and it doesn't do anything good for you if you go get it. They will say its for a security issue but it's really just to try and catch people with non genuine Windows. If you have a genuine Windows that starts up with that message or see that not genuine thing in bottom rt corner of desktop get rid of that update. Do not try to install the so called WAT removers utilities as they almost all contain malware and viruses and don't do anything to fix the initial issue. Actually even having a Windows serial keygen or crack or windows activator/WAT remover somewhere and Windows detects it, and you have the WAT update installed you will get that fake "not genuine" message even if your windows is genuine. If you are doing a clean install and don't have that update yet, keep a close eye for it if you use Windows update as soon as you see it offered you need to hide that update or they will keep trying to make you install it. They will offer it every time until you hide it.

    This doesn't work. So what is the repair option for when this doesn't work? No matter what option selected from Advanced boot menu (f8) still just boots to the recovery environ. Please no replies about using System Restore or clean installing Windows. That is not acceptable answers to how to repair anything. Windows 7 sp 1 64 bit

    I'd specifically note where there are spaces in the command inputs. It was pretty hard for me to tell this the first time around. But the fix works great! Now I just have to figure out why windows keeps messing up the registry periodically even when I haven't changed anything from one boot to the next...

My work laptop went into a loop and although I was delayed for half a day, I was able to repair it and get everything working again without having to send it off to our IT guy who charges a fortune and was talking about a full system wipe.

      From the conclusion: "Note also that these steps don’t guarantee success – you should be prepared to reinstall Windows in the event that fixing the reboot loop fails."

      This isn't really a reboot loop problem of course - your will need a boot menu editing tool to remove Windows 8 and thereby end the OS choice menu

    Christian, thanks for your article.

    I've not been able to start windows7 for about a week since the last Windows update and my kids installed latest iTunes. I've tried repair and reverting back to previous save points incrementally until I'm pretty much back to the original win7 configuration (which for this machine was early 2012). I then tried your fix above but no luck. Still fails on Starting Windows -> bluescreen of death -> startup repair.

    Can still get to cmd prompt.

    Feels like the next option is reinstalling Win7.

    Any other suggestions?

    Thanx Will

    Hello and thanks for this great article, it is incredibly clear and easy to follow.

    However, I still have a problem.
    My "loop" started after installing Windows Updates a few nights ago.

    Following your article, everything went well up until the copy function 'copy *.* ..' from the regback folder.
    Everything but Software gets copied and gives me an error message indicating that it is not able copy it due to an I/O error; but it copied the rest, a total of 6 files.

    The Software file is about twice as large as mentioned in the article, displaying 47mil bytes; yet it still fails to be copied.

    Booting up results in the same loop as before; Startup repair starts and then mentions that it can't be automatically fixed.

    Anything I can do?

    THANKS AGAIN!

    CD \windows\system32\config that it would say "the system cannot find the path specified. I don't know what that means and im afraid to say that im a noob to computers.

So I guess that's why it will have to be formated now. Anyways, is it possible that my personal files have been overwriten by the instalation of Windows 8? I'd like to at least save my files but I can't find them in the Windows.old folder, the User folder there is empty. Is my data lost for good? Thanks for reply

    How to Fix Windows Explorer Has Stopped Working Problem
    Sometimes, just when you thought your computer is in a perfect condition, your windows explorer stops working, freezes up, and restarts. You get error messages like “windows explorer has stopped working” followed by “windows explorer is restarting”. You have done nothing wrong but the machine keeps stressing you out. Worry no more as this article will you show you how to solve the problem.

    You do NOT need to perform a system restore to solve this problem. Nothing is wrong with your computer either. Inserting your OS installation disc and booting off the disc cannot fix the problem. The solution to the problem is very simple and only involves changing your thumbnails to icons. Follow the steps below to fix the problem and your computer will return to stability.

    1. Click on the “Start Menu” and go to “Network”

    Start Network

    2. Click on “Organize” at the upper right corner of the window. A drop down window will pop up. Click on “folder” and “search options”.

    search options

    3. On the folder option window, you will see three tabs at the upper right-hand corner. Click on “view” and SELECT “always show Icons, never thumbnail”. Next, DESELECT “display files Icon on thumbnails” as illustrated below.

    Display Files Icon on Thumbnails

    4. Click OK and you should be good to go.

    It would also be good to note that if you do not have the Windows 7 install disc, whether from losing it not not being given one, you can download the .iso image for free from Microsoft's Digital River storefront. You can find the links listed over in this wiki. Just download the image, burn it to a dvd with a program such as ImgBurn, and boot to it.
    http://en.community.dell.com/support-forums/software-os/w/microsoft_os/3316.2-1-microsoft-windows-7-official-iso-download-links-digital-river.aspx

    Alternatively, if your laptop doesn't come with a dvd drive, you can use a usb drive just as well. Microsoft has a little program to put it on a flash drive for you. You can find it here.

    The fun part comes when this part...

    "...then click Repair your computer. A list of installed operating systems should be displayed – select Windows 7 and click Next."

    ...does not work as advertised.

    I've had Windows 7 boot process hose itself so bad that even though it displays the installed OS, it cannot SELECT that OS...and thus never brings up the System Recovery Options - which you need in order to get to a command line.

    In other words, Microsoft made it impossible to get to the command line a la the previous forms of Recovery Consoles in this situation! A MAJOR PITA!

    The only thing you can do then is boot a live CD which has had some sort of Windows 7 boot database editor installed - which is hard because most of them rely on .NET which usually isn't installed on a Live CD - although it is possible. If you don't have something like that, you are totally SOL - the only recourse AFAIK is a complete re-install...

    It's almost as if Microsoft really wanted to make it much harder for PC support techs to fix these sorts of problems. They tried to automate the process but at the same time did not allow for the possibility of their "automated repair process" to itself fail miserably.

    Fortunately I only saw this occur on two Windows 7 machines shortly after installation. Subsequently they ran for a year with no problems. But it happened twice on one machine early in its history, both times requiring a full re-install.
