So I just got a copy of Windows 7 pro and installed it.
There's just one itty bitty HUGE ENORMOUSLY BAD PROBLEM.
I can't boot to XP anymore! I know (I am 100% POSITIVE) that I did NOT overwrite the XP partition, but it doesn't show in the boot manager and I can't get the boot select screen to show up!
This wouldn't matter as much if it weren't for the fact that windows 7 isn't recognizing my 360GB HDD, which has all my movies and music on it.
