So after 10 BSODs and 5 hours of recorvering, formatting and reinstalling we finally managed to reinstall Windows 10 on my friends computer! Yaaaaah! I was so freaking stressed and frustrated but now its all good

Anytime Windows has a BSOD, restart the machine and immediately launch Powershell or Console as Administrator, then use the System File Checker, you'd be amazed how many times a system file just needs to be repaired/replaced instead of having to do a whole wipe and reload. I'll drop the command below. Cheers!!

sfc /scannow

@bvader Thanks a lot :-)
