Reinstalled Windows & Grub, but windows wont boot... help!

[Andrew Konosky]

I reformatted my windows 98 C: drive (/dev/hda1) and installed WinXP, 
and of course it overwrote grub. I put in the FC3 dvd and did 
grub-install /dev/hda but it said it couldn't find /sbin/grub. I tried 
the knoppix cd, entered the grub prompt, and set grub up with these 
commands:

#: root (hd1,0)    --> hdb1 is my Fedora /boot and hdv2 is the LVM with /
#: setup (hd0,0)

Now my grub screen comes back up, and I can boot both my fedora and 
debian installations, but WindowsXP just returns me to the grub screen. 
I tried doing it by the grub command line but it does the same thing. 
How to I get XP to boot?

Here is my grub.conf:
