8. Run System Restore in Windows 10/11

If you are able to boot into Windows normally, then read our dedicatedWindows system restore guide. But if you’re unable to boot into the OS at all, follow the steps below.

  1. To run System Restore on a PC thatcan’t boot into Windows, keep turning on the PCuntil it restarts 3 times, after which Windows will automatically load the Advanced Startup Menu. This is automatically triggered based on how many times your OS failed to initialize. When you see the below screen, click on ‘Advanced options‘.

  2. When you are at the Advanced Startup Menu, navigate toTroubleshoot > Advanced Optionsand click on ‘System Restore‘. Follow the on-screen instructions to restore your PC to a previously made system restore point.

If you have recently updated Windows, or have installed new programs, a system restore point tends to be created. So, even if you haven’t made a system restore point prior to having the INACCESSIBLE BOOT DEVICE BSOD error, it’s worth checking this fix out since there could be a restore point automatically created previously for you to use during this situation.

9. Update Your Computer’s BIOS

In case your PC is not booting into the OS, you will have to use another PC for preparing the BIOS update on a pen drive and then proceed to update the PC affected by the BSOD. We have adedicated BIOS updation guidecontaining detailed instructions.
