Hope it works for you. Thankfully, getting XP into the boot menu is not particularly difficult. Thus, a copy of ntldr must be installed on the Vista partition. Open My Computer. Select "Show hidden files and folders" and uncheck "Hide extensions for known file types" and "Hide protected operating system files recommended ".

Preparation Assumptions: In this tutorial, it is assumed that you have a single hard disk in your computer, and your computer meets Windows Vista's system requirements.

I followed this tutorial with Windows 7 instead of Vista and this worked flawlessly! Create two partitions, C and D. Install XP on D. I remember from previous experiences that XP still called its drive C even though it is technically D. First of all, drive letters are defined within the context of an operating system not the BIOS.
Therefore, the idea of XP "calling its drive C even though it is technically D" isn't entirely correct. Second, XP always calls the active partition on the first hard drive "C:" in the installer stage. It doesn't matter what size the partitions are. Of course, if neither partition is marked as active, it might choose based on the size or order of partitions Third, the main point of this tutorial was the separation of both systems.
Even if you successfully install XP on C: and Vista on "D:" the Vista installer still calls the active partition "C:" but renames the system partition to C: even if it was different in the installer window , it would work perfectly, EXCEPT for the fact that Vista's boot files will be on the active partition in this case, the one XP is on.
This would prevent you from just deleting the XP partition, and would give you issues if you're trying to boot from GRUB for example.
