Thanks a million. I worked for more than 6 hours on a very important customer PC that wasn't backed of for a long time and had to run the chkdsk 6 times before the bootrec /fixmbr let me get to the login picture just to realize that my customer had given me a wrong PC and the one I was supposed to fix was OK. However, my time was not spent in vain, because thanks to you, I have now learned how to fix this kind of problem, so once again from the buttom of my heart: THANKS!!!!!
THINGS TO KNOW: 1. Windows may not always be located on the "C:" drive. 2. System registry is no longer backed up in the RegBack folder since Windows 10 version 1803. 3. My pc is still dead and I'm going to use Windows installation media tool on a flash drive to boot it up and then system restore it.
Dude first one worked perfect. You saved me from having to buy a new laptop. Thanksssss

Tried everything, did not work. It didn’t register a Window installation either. My Lenovo (D:) drive is full, but Window is on C:. Don’t know if that has anything to do with anything.

It does that every time I use system restore after reinstalling windows 10 without updating the drivers and selecting modules installer.
Thanks man the secont trick a make pass a pass and my windows gone back thansks from brazil.
it didn't work for me. the last option - the regback folder is empty :-(
Regback automatic registry backups have been disabled in recent versions of Win 10. It can be enabled manually after you repair this bsod and boot your system just google enable regback... If all else fails try booting from install media and running SFC offline, Just google SFC offline.

It's because Windows isn't saved of c: sometimes. First type c: and press enter, then type dir and press enter. Check if in the list it says Windows if it's does then idk what the problem is. If it doesn't type d: and press enter, then type die and press enter. If that says Windows then your windows is saved in the d drive. Follow what the vid says except when typing c you replace it with d. I hope you solve it!

first option did work perfect for me even when i couldn't type in a user password. whitch obviously was put in by the dealer where i got the pc from years back. mine runs windows 8.1 what is causing this failure? is it a dying harddisk? (did not see any bad sectors in the dosbox when i typed the chkdsk thing) or is it just the update process that didn't fully completed as an incidental thing to get used to in the cumming future again sometimes. infact the error did occur after the PC asked me to restart to install some updates as it normally does sometimes. but this time it failed causing this situation. thanks.
