If those two commands can’t fix the problem, you might have to use DISM scan instead. To do that, just run this DISM /Online /Cleanup-Image /RestoreHealth command.

  • Dism /Image:C:offline /Cleanup-Image /RestoreHealth /Source:c:testmountwindows
  • Dism /Online /Cleanup-Image /RestoreHealth /Source:c:testmountwindows /LimitAccess

These commands will check for file corruption and fix any corrupted files on your hard drive that might prevent Windows from booting. Keep in mind that this isn’t a universal solution, so it might not work if the problem is caused by your hardware.

It seems that everything is lost when DISM fails on Windows 10? Check out this quick guide and get rid of the worries.

Solution 4 – Make sure you’re using UEFI

Many users reported No Boot Device Available message after a BIOS update. If you’re getting this error message, the problem might be related to your BIOS. To fix the issue, you need to switch from BIOS to UEFI.

This is a simple process, and in order to do it, you just have to enter BIOS and change a single setting. Since there are many different versions of BIOS, we strongly advise you to check your motherboard manual and see how to switch permanently to UEFI.

After doing that, the error message should be resolved and your PC should start working again.
