Use another PC to create a live USB with something like Ubuntu. Boot it, access your drive and copy the files from it. Then format and reinstall Windows.

Posted

So I try to turn on my PC today and I get greeted with the BSOD with the error code above. I cannot boot into windows at all, even safe mode or disabling driver certification thing doesnt work.

 

So I try most things on website, like in troubleshooting use cmd and so stuff like sfc /scannow and dism stuff aswell, but these have no apparent effects or dont work at all. 

 

After an hour I decided to reset my pc and keep my files (some are pretty important which I have not backed up) but each time i do this, at around 30% it would fail and say nothing has changed. What do I do? 

 

Any help is greatly appreciated!

Used to be everywhere in LTT forums, had a break which lasted apparently 1 year LOL. 

Gonna get up againnnn.

Wake me up if I sleep again like Oppy.

So I found a way to copy my documents to a usb, after that finishes, I will try the options you gave me. If these dont work I will just reset the PC considering now I have the files again, will update if the options you gave work or not.

Oh well I managed to reinstall using media creation tool and I guess it's fixed. Will be checking for disk errors now so I can be certain. Thanks for any help
