Unhappy Redhat & WIndows...another GRUB & MultiBoot Problme

I had a working winxp and yoper distribution installed on my spare pc. As my windows was getting buggy and I was bored with yoper, I thought of re-installing windows XP Service Pack II and Red Hat Linux this time around. I installed winxp first, worked fine, and then I installed Red Hat.
The problem is WInxp doesnt boot.
The message I get is
chainloader +1
Now, I am guessing that since grub reaches to the stage of chainloader +1, this is essentially a windows problem. So, I re-installed again but the same problem.

I am outputting here the output of the command fdisk -l
Disk /dev/hda: 40.0 GB, 40020664320 bytes
16 heads, 63 sectors/track, 77545 cylinders
Units = cylinders of 1008 * 512 = 516096 bytes

Device Boot Start End Blocks Id System
/dev/hda1 * 1 40641 20482843+ c W95 FAT32 (LBA)
/dev/hda2 40641 77536 18595237+ f W95 Ext'd (LBA)
/dev/hda5 40641 60961 10241406 b W95 FAT32
/dev/hda6 60962 61164 102280+ 83 Linux
/dev/hda7 61165 62204 524128+ 82 Linux swap
/dev/hda8 62205 77535 7726792+ 83 Linux

I will really appreciate if someone can help me fix this problem. Fdisk also reported that the number of cylinders on this disk were set more than 1024 which might cause a problem with boot programs of windows. Is this the case. WHat should i do?
Appreciate your help

This may be a shot in the dark, but you could try this:

1. Boot from Win XP installation CD
2. Select "R" to boot into Recovery Console
3. Type in chkdsk /p and hit Enter
4. After chkdsk finishes, type in fixboot and hit Enter. If it asks you are you sure just say yes.
5. Remove CD
6. Type exit and hit Enter
7. If you're the religious type, you can say a quick prayer if you like
8. Let me know if it worked

CAUTION: I'm not 100% sure this is the best solution, so give it a try only at your own discretion.

Also, what I find funny is that fdisk says the disk is set to more than 1024 cylinders, yet in the extract you provide it clearly lists a total of 1008...? Virus maybe?
