Is it a bad idea to have both Vista and Xp installed on the same (partitioned) hard drive?


No. Nothing wrong with that. Apart from the fact that (obviously) Vista's Media Center's not going to be able to record shows while you're booted into XP.

You might have to jump through a couple of hoops to get it working, because the Vista boot loader's completely different from the old NT/XP one. Using Google to search for "dual boot xp vista" turns up about 2 million hits, though. This one looks promising.
