Hello, September last year I purchased a pc magazine with Windows 7 RC on it. I dual booted with XP & everything worked fine. When I started up XP, My Computer stated that XP was on C:, my DVD Drive was D: & Windows 7 was E:. When I started up Windows 7, My Computer stated that Windows 7 was E:, my DVD Drive was D: & XP was on C:. 2 weeks ago I purchased Windows 7 & have again dual booted with XP. When I start up XP everything remains as previously stated but now when I start up Windows 7, My Computer states that Windows 7 is C:, my DVD Drive is D: & XP is E:. When I restart XP, it is read as C: again. My pc is running fine & installing programs without issue, but I was just wondering if the drive letters are supposed to change as they are and am I likely to run into any problems if I leave things the way they are? Thanks, Shantelle.
