When I install vmware it automatically finds my windows xp partition and calls it bootcamp, I can't boot into it but I think in my case its because Time Machine partition is on the same drive as xp. It comes up with some error I can't remember what.
It's funny cos I was just thinking when did I last use xp? I can't remember but its weeks ago.
When I had linux I had a super stable system but would always end up back in windows cos there was something I needed, havent encountered this yet with osx.
Oops I rambling!
