I've tried many different solutions that the internet offered me: boot to safe mode, factory reset, system commands, disk scans, nothing, absolutely nothing worked. The factory resets would end with failure and safe mode couldn't boot since it would lead straight to bsod. I've been trying to fix this problem for 3 days to no avail. I have very important files in my hard drive that would be a pain to lose. Please people, I'm in dire need of help.
