Issues with System drive in Disk Management on a Dual Boot system

[Guest]

At the moment I have XP x64 and Vista x64 installed on my machine. The way
I'd like to have it setup is where the two operating systems do not assign
drive letters to certain partitions--such as the other's System drive. Well,
Vista is saying that the x64 partition is a (the?) System drive, and I have
not found a way to change that. I know for sure that I did not install it to
that partition, that in fact it's on the C partition.

I've done a little searching of the Vista newsgroups, and found one person
who had the same question but in the end his question wasn't answered. If
someone could help me out with this, that would be great!

The operating system that is currently running assigns the drive letters.
Each operating system assigns a different set. If you want to have
partitions which are not assigned drive letters, use a partitioning tool to
hide them from the operating system.

I was able to eliminate this problem by disabling the Win XP system drive in
Win Vista and vice-versa.

Hope this helps,

To get a good idea: You have the two OS's on different HDDs, correct? Mine
are both on the same drive, but different partitions. While it is possible
for me to put them on different drives, I'm wondering if I can solve this
problem without doing so.

If your meant you have them on different partitions on the same physical
drive, then how did you disable the other system drive? I haven't seen it...

Drive letter changing between XP and Vista is a result of installing Vista
via booting from CD at computer startup- installing Vista from within XP
does not cause drive letter exchanges.
