How To Fix INACCESSIBLE BOOT DEVICE Error in Windows 11

inaccessible boot device windows 11 – How to fix

If you receive INACCESSIBLE_BOOT_DEVICE error after you have upgraded to Windows 11 or Windows 10, or after you used Reset in Windows 11, then this posts suggests a way to overcome the issue.

The INACCESSIBLE_BOOT_DEVICE bug check usually indicates that the Windows operating system has lost access to the system partition during startup. If this happens, the system usually shuts itself down after showing a Blue Screen or Stop Error to protect itself from probable data corruption or loss.

Here are a few suggestions you can try to resolve the issue. See what applies in your case:

1] If you think a boot device may at fault, you may need to edit the boot options.

2] Remove any recently added hardware.

3] Check if the disk firmware version is incompatible with Windows 11. If not, you may need to update to the latest firmware version. See if you need to update the BIOS.

4] If you recently added a driver, restart your computer, enter Advanced Boot Options menu, select the Last Known Good Configuration option. You may boot Windows 11 into Safe Mode and try a system restore or a Rollback.

5] If you think the cause could be hard disk corruption, Run Chkdsk /f /r on the system partition. If you cannot boot into Windows, use the Recovery Console and run Chkdsk /r or run Chkdsk from the Repair Console.

6] If you just upgraded to Windows 11 and then you are seeing this error, then, download and use Media Creation Tool, using another computer and save it to a USB device. Use it to perform a clean install, by clicking on the setup file or booting from the USB. If you are asked for a product key, click on Skip this step. Windows 11 will activate itself, when you sign in with your Microsoft account.

7] If nothing works, you may have to fresh-install your earlier OS, viz. Windows 10, Windows 8.1 or Windows 7 operating system, activate it, upgrade to Windows 11, activate it and then clean install Windows 11 using ISO.

This tutorial was performed on a Windows 11 computer. This will work with all major computer manufactures that are running the Windows 10, Windows 7, Windows 8 and Windows 11 operating systems (Dell, HP, Acer, Asus, Toshiba, Lenovo, Samsung, and so forth).
