I reinstaled Windows 10 on my laptop and after getting all the apps back I decided to run Windows 8 on my VM but it did not boot as the same for the other, in the end I launched Windows Vista and after 1 hour it booted but not correctly and it was barely responding so I had to shut it down
I remember something similar happend last time I reinstalled Windows but it gave me a error message then and now I don't even have that..
What caused this and how do I repair it?
