I had a problem that has been "resolved" but i want to know what really happened. I was on my phone infront of the computer, had opened steam,discord nothing unusual. Suddenly i see a blue light i look up and i see its a BSOD. Windows restarted itself and started an automatic repair after a few seconds got an error that it could not repair it automatically. I went "Exit and enter windows 10" something like that, windows logo appeard and just before the homescreen appeard again BSOD!. i tried chkdsk /r and got an error "write protected disk" then i tried chkdsk c: /r and it started scanning the files, after 20minutes around 50% i got an error saying "unspecified error occured (766f6c756d652e63 470)", then i tried to go into safe mode but i forgot how to, so i started checking around BIOS, and i found out that my boot option 1 was my HDD instead of the SSD where windows is installed, changed it and now windows boots normally without bsod. What could this be???
