I installed my copy of Windows 7 in the second partition of my HDD. I keep my Windows XP in my primary partition (long story short: I'm migrating to Windows 7 but I have a lifetime of work built on my XP system that I can't afford to lose. Thus, Win7 was installed on my system on a purely experimental basis). What was my surprise when I first booted Win7 and learned THAT IT FREAKIN' SWITCHES THE PARTITIONS TO MAKE ITS PLACE AS C:\ ... I'm worried that the frequent switches between C: and D: will screw up my HDD MBR. How do I stop Windows 7 from doing it?!
