I was trying to upgrade from windows 8 to 10. and after deleting every personal file, the C drive (I partitioned into 2 drives) still didn't have enough space. so I found that the culprit was the WinSxS folder. And the idiot me decided to delete the old files, thinking it didn't matter. Now I can't even get into safe mode or login to my desktop. Is reinstalling windows my only option? If so, if I download windows 8 installation files online and put into an usb, will I still be able to upgrade to windows 10? since most copies online are pirated. Is there a way to use CMD to get my existing product key and use that same one to input it into the pirated copy? Any other ideas would be appreciated.
Thanks for any help in advance. I just want to maintain a legitimate copy of windows and upgrade to windows 10 before microsoft's deadline.
