I bought myself a new cpu and now i'm unable to boot to my linux drive

[Thematemat]

Well i was reinstalling the Linux again and again and again and now it finally works (at least for now). I have good backups so no worries no data was lost in this process. Yes i'm aware that there might have been just a much simper solution to all of this like some terminal magic but I'm a new Linux user so i don't know how to do that yet and the google was very unhelpful too. I'm glad that my PC works again fine so i hope that's end of this whatever this is . My rant about broken computerz
