Windows 10: Can't boot on Windows, stuck in BIOS

Hi!I recently just recovered a sibling's PC by resetting the password using approximately, and better, this forum How to reset a Windows password with Linux Opensource.comI then made a few Windows updates.The first wave, and the first reboot, everything fine.But the second one, I got one update that said "download failed" but as it was written "download" and not "installation", I rebooted anyway as it should not have caused any problem.But maybe a problem occured during the reboot. Now I keep rebooting in the BIOS. There is no boot option. When I try to add one for example PCI\DevicePath\..

Windows stuck in automatic repair; Can't access BIOS/ boot menu

I've changed the boot order through both BIOS and the boot manager, as my original post stated. Neither did anything, but both were functional in the past. Neither listed the windows boot manager, either. Previously, it would boot just as expected whenever
other media was set as the first option, so I'm pretty sure there are no issues there.

As my original post suggested, I've already tried out the steps you gave. I've gone through all the options listed in the boot menu, UEFI or not.

My BIOS and boot menu settings were at their defaults when all of this started, so that's been tried already, if those are what you're referring to.

Hello,

We would like to ask some additional information to better isolate the issue:

Stuck in Windows 10 Upgrade

My computer seems to be stuck in a Windows 10 failed upgrade loop. I was running fine on a beta version of Windows 10, and then I came downstairs one morning to see it repeatedly booting, attempting to repair, then rebooting. The steps I've taken to diagnose are:

• Attempting to boot off a USB drive (with all drives disabled in BIOS) - this fails at the point of the blue windows screen
  
• Attempting to boot the machine itself and getting into "repair/safe mode" using F7
  
• Looking at the BIOS for obvious failures (e.g. RAM that should be there is missing) - nothing obvious is wrong.
  

I am fairly certain the build version was 9926. For many months, the system would attempt to upgrade, and then say "it failed" for some reason and roll back.

Suggestions for next steps?
