So you guys adviced me to switch to new os. I got new windows 8.1 x64 and installed it on my pc together with old os windpws xp x32. Just to check it if I like it. So I decided to give it a try but currently nothing works good from old os. And i decided to delete old windows xp and all instalations and drivers deleted with it like and my games and all stuff. But I cannot unistall it/format local disk. I want to delete all except drivers that I onstalled for w8.1 and os w8.1 and delete other stuff but I cannot. How to make it?
