Dual Boot XP and Vista. Now going to boot into XP and getting STOP error

[Tombo3241]

Okay.. so I am trying to dual boot XP and Vista b/c I need XP operating system for work. I has Vista installed first then tried to load XP but I could not for the life of me get that to work. So what I ended up doing was installing XP first and I was able to get that installed and working. I downloaded the necessary drivers for that and had it good. Then I loaded Vista and had that put and downloaded all the drivers and necessary information. I restarted and wanted to boot into XP ( had the options for both ) I got the XP Pro loading screen and the blue bar went 1/5 way across the screen and I got the message of:

A Problem has been detected and windows has been shut down to prevent damage to your computer.
Technical information:
STOP 0x0000007B (0xF78AA63C, 0xC000000E, 0x00000000, 0x00000000)

I have a feelings its by XP bootloader menus but if I could fix it I wouldn't be postin'

I appreciate any information/help I can get. Thank you for at least reading.

I'd suggest you start by booting to the Recovery Console (boot to the XP CD and choose the first repair option) and run chkdsk /r - let's see what happens after that. I'm guessing it's not the bootloader if you XP actually starts to load.
