Windows 10 Cannot Boot all of the sudden due to corrupt files.

[somber hemlock]

So my friend was just using her computer as normal and all of the sudden it froze and discord crashed so she restarted windows and now it wont boot saying "Windows could not start because the following file is missing or corrupt. D:\Windows\System32\Config\SYSTEM" ive tried just about everything now and theres nothing in her regback folder either.

whoops accidentally attached the same image twice

if you have access to another pc you can try to install the drive in that one and just copy the files you need from there

usually it's better to just start fresh when windows is messed up to this point
