So I decided to install Windows 7 rc on my comp. Since I have two hard drives, I installed it on D (C was the other one) and thought that everything would work fine. After installation of Windows 7, comp restarted and everything went fine. Then I thought that ill check if I can now dual boot Windows xp. So I restarted but no dual boot option came. Again, I restarted but this time I pressed F8 but still no dual boot option in there. So, have I messed up the whole thing and now have Windows 7 only?
