Multiple Boots on Same Hard Drive a Problem? (hd, server, sound)

[Jesse69]

My old it 920 computer - I had 3 OS boot installs but each one was on a different hd so no problem. But my new i7 2600K computer - I tried 2 installs of Win 7 Prof on 2 partitions on the same hd. Now the problem I ran into was that they share the same 100 gb system reserved hd space. When I installed a non oem sound driver on my secondary OS install, it gave problems to my sound driver install on my primary OS install.

So if you want multiple boot do you have to resort to putting them each on a different hd? It's not advisable to put multiple boots on the same hd?

I have Server08, Win7, and XP all booting on one drive. No problem. As long as each OS is in a separate partition, I don't see how that little 100MB partition would have anything to do with installing a sound driver.
