wont boot back to xp
 

I just installed RedHat 9 last night on a new compaq cause i wanted my computer to stop telling me what to do, and stop it from selling me crap.
for the most part it went great except i must have done something wrong in identifying where winxp was for the grub booter when i try to boot into xp it starts to load (banner w/scrolling bar) then i get a different screen saying
xmnt2002 not found-skipped autocheck
autchk not found-skipped autocheck
then it reboots
this has gotten me in trouble since my sister is partial to xp and will probably kill me in my sleep if i don't get it running again

the partitions are set as
hda1 the compaq sys recovery
hda2 windows and programs from compaq about 100gb
hda3 unnasigned as far as i can tell .7mb
hda4,5,and6linux 10gb

linux boots fine but the compaq recovery and xp don't they are all in the grub but menu

i am new at this and trying to learn so i need it as simple as possible
thnx

i have redhat 9 and xp dualbooting on a dell 4550.
installed xp first then defragment the hard drive.Then i installed redhat 9. I used the grub bootloader installed on the MBR.now when i boot i have a choice between redhat or DOS (win XP).
