Hello Guys, i need your help , so few months ago i upgraded to windows 10, then i wanted to downgrade to windows 8.1 , there was option ,get back to windows 8.1 , i did that but when pc turned on , windows was corrupted it was all black screen , somehow i managed to open taskmanager then run and go to windows update and update to win 10 again , now i want to downgrade to windows 8.1 but that option is gone , + i would not use it ,but in recovery options , Restore Factory Settings , and it says that it will install windows that come to this PC , so it means that it will install my old 8.1 right ? and will it have problem like it as on downgrade, cuz downgrade is different its just downgrading and this will delete everything and install 8.1 , and should i do it ? i mean will i have some problem doing that ? i hope not , pls answer .
