As i read in some message that i could "easily" upgrade from 8.1 to 11 i started the procedure..... Upgrade stopped somewhere and it got stuck in windows 10.... Now i can't access windows 8.1 nor 10.... Can i delete windows version on my mac completely and possibly re-install 8.1 (i have a licence key + cd)? And how do i do that? Does it affect my mac in anyway? Safari 15.6.1 Imac 27inch late 2013 Greetings Jan Heine Blaauw Heerenveen Netherlands
