[@dragonice3968]

hey, first i wanna thank you for this guide, i had the issue where the windows 10 went to none stop loop with this blue screen. it happen because i installed a legit game dont know why it messed up my pc(brand new), so i tried EVERY possible tutorial to address the issue i had, trust me i have been sitting on this issue for 3 hours. none of them really helped me i was always getting in this loop with the blue screen i was about to give up and maybe call a specialist to fix my PC for money of course. anyway your first step really saved me! i tried safe mode and reset the PC and boot from USB and other methods people gave and nothing worked until your first step kicked in! so thank you sir :)

I had another problem and fix: In my system32/config/RegBack there were 0 files, there was nothing. In order to fix my issue I had to find those files and put them in there. Luckily I had a back up of my old ssd where I extracted those missing files and put them there. That fixed my issue

[@ValiumMediaTech]

Thanks for your valuable addition.

[@Ikuno10424]

@@ValiumMediaTech No problem. I just don't know though if using bootable CD or USB Drive with Win 10 could fix the problem as well in order to re-create the missing files in RegBack. In my case I was just lucky to have a back ssd.

Theres no reg files in my pc rn, how should i fix that?

[@ompongongskie7214]

help, i dont have any files in regback, what to do?

[@chrisfragkou]

Same here my pc wad fine I had a small issues with my back up driver but nothing to worry myself about, but of course I had to dig through it and when I had no other clue what to do I contacted microsoft support and they suggested system recovery and then bsod loop commenced, it's an amazing feeling when you know you fd up your pc with your two hands. I'm still trying your methods I'm at the last one hope I have file in regback

[@juscripz1362]

A fix for most boot loop issues is to clear your disk or ard drive completely windows included and then re downloading windows sadly you lose evry songle personal file besides backed up files

[@ValiumMediaTech]

This is the final solution when all steps filed.

[@mikaa1221]

I tried everything and nothing worked because the bsod error appeared after i reinstalled windows, i get stopcode oxcoooo21a and i searched on yt a lot as well but none of them worked, what do i do

[@ValiumMediaTech]

If all suggestions not worked for you, you have to reinstall windows.

[@ابرهيمالقطامي]

Can you tell me What did you do to solve this problem?

[@lanikaidunne7774]

what if there is no files to copy out of that RegBack folder in step 5?

[@ValiumMediaTech]

That's mean there registry backup was not enabled, so you have to try another repair method.

[@lanikaidunne7774]

@ValiumMediaTech figured it out thank you for the insight though, I know alot more now. I ended up using the usb method
