If Windows 10 won’t start after update

Your PC will most likely cause you trouble more often than you expect, especially if you’re running Windows 10. While Windows updates are supposed to enhance the performance of computers running Windows, the updates sometimes lead to a lot of errors. Some people have noticed that Windows 10 won’t boot after running Microsoft updates. If you’ve encountered this issue, here are possible ways to fix the error.

How to fix this problem


Method 1: Perform Startup Repair

Running automatic startup repair can help to fix a couple of “Windows 10 won't start” issues. To try this method, you have to repeatedly reboot and shut down your computer using the power button until it launches the Automatic PC Repair screen.

  • Select “Advanced Options” or "Troubleshoot"
  • Select “Startup Repair” and follow the subsequent prompts to repair your PC

Alternatively, you can boot the computer from a bootable media (installation disk), and also use the “Advanced Options” link to launch “Startup Repair”.

By the time “Startup Repair” has completed, reboot the PC. It should be working fine now.

Method 2: Enter Safe Mode

Booting to Safe Mode is one of the best ways to troubleshoot PC problems. For this method to work, repeat the initial steps discussed above and launch the “Advanced Options” screen. However, this time, you won’t be selecting “System Restore.” Instead, follow the steps below.

  • Click on Troubleshoot >>> Advanced Options, and then select “See more recovery options”.
  • Select “Startup Settings” and click on the “Reset” button.
  • Navigate using the keyboard "Arrow Keys" and select "Safe Mode".

Method 3: Uninstall Windows update files

Another way to fix this error is by uninstalling Windows update files. You may see this error as a result of conflicting updates. So, you have to EITHER boot the PC from a disk and then enter into Safe Mode by typing “bcdedit /set {default} safeboot minimal” in CMD; OR, you can boot directly to Safe Mode.

The trick to be able to access your desktop, so you can go to Update & Security >>> Windows Update >>> Advanced Options >>> View Your Update History >>> Uninstall Updates

At the last screen, “Uninstall Updates”, you can select all Windows updates and uninstall them consecutively. After that, reboot the computer normally.

Method 4: Run the rebuild or repair MBR commands

Fixing the Master Boot Record can help to solve this issue. This is achievable by launching Windows Command Prompt in Safe Mode or by booting the PC from bootable media (installation disk). Either way, launch the command line and run the following commands in order:

bootrec /fixmbr

bootrec /fixboot

bootrec /rebuildbcd

These commands should fix your computer’s MBR and get your PC working fine after a normal reboot.

Method 5: A clean install of Windows 10

If you're still unable to solve the "Windows 10 unable to boot" issue with the methods discussed above, then a fresh installation of Windows 10 on the computer may be helpful. However, a clean installation will definitely remove all the data saved on your storage drive. Thus, before running this action, it is advisable to create a disk image file using DiskInternals Partition Recovery. This image will serve as a backup copy for everything that’s saved on your computer. After creating a disk image, you can go on to reinstall Windows 10 on the computer.

But even if you lose some files during the whole process, DiskInternals Partition Recovery can help you to recover those files in four simple steps.
