First and foremost, if the specific computer model in question was
designed specifically for Vista, there may well be no WinXP-specific
device drivers available to make the computer's diverse components work
properly. If this proves to be the case, installing WinXP in a virtual
machine would be your best - possibly only - option, anyway. Consult
the computer's manufacturer about the availability of device drivers.
Secondly, adding another OS might void any support agreements and,
sometimes, even the warranty. Again, consult the computer's
manufacturer for specifics.
If WinXP do device drivers exist, then you can proceed.
Normally, the older OS must be installed first unless you wish to
acquire and use some 3rd-party partition and boot management utility.
(In which case you have to follow the instructions provided by whatever
3rd party solution you select.) However, this KB Article (not for the
faint of heart or technically-challenged) explains how to repair the
Vista boot process after installing WinXP:
Windows Vista no longer starts after you install an earlier version of
the Windows operating system in a dual-boot configuration
