install XP pro after vista is already installed, dual boot ?? how ?

[Someone]

Hi,

I have Vista Ultimate installed and running ok as of now but, game
perfomance is 1/2 of what I used to get with XP on the same machine. I would
like to install XP to another drive on my system to use for gaming only, and
boot to vista for everything else.

Is there a fool proof way to install XP to another drive after Vista is
installed with out having to rebuild or re-activate vista ???

Please help if you can !!!!!

How to dual boot Vista and XP (with Vista installed first)

I installed to a separate drive and use BIOS to change from one to another.
It works well..

That looks like it might help but, not sure. Do I need to create a new
partition on the same drive for XP ? I have 3 hard drives in this machine. I
just would like to take one of the other drives (not the Vista drive) and
install XP to have a dual boot system.

Just want to be clear, I can not damage my Vista install, too many apps I
need for work, so it does need to be fool proof.

Any other thoughts here ?

Thanks

I do want to be able to use the drive from both Vista and XP, as it's used
for file storage but, has a lot of free space. So to lock out a drive, it
wont help here.

Never mind, after looking it up (and reading the link you gave) it looks
easy. Too bad I don't have time for the next few days to do it. Oh, well. If
I have problems I'll post back

Thanks !

Those apcmag guides are good, go for it!

It doesn't lock out a drive, neither is it dual boot. Essentially, what I
have is a machine with two parallel installations, one Vista and one XP.
Whichever OS is running can see and use all of the drives.
