a long story here, but basically I had windows xp on sda1 aka (hd0,0) and ubuntu on sdb5 aka (hd1,4) and they were booting fine. Something messed up with ubuntu, I reinstalled, and tried to fix grub.. in the course of it all I believe I accidentally ran 'setup (hd0,0)' instead of 'setup(hd0)' to copy grub over.
I've tried fixing the MBR with ms-sys but to no avail.
At this point the GRUB boot menu lets me boot into linux, but if I try to boot into winXP, it quickly flashes "GRUB loading stage2..." and then puts me right back into the GRUB boot menu again.
Is there anything I can try to fix this or am i screwed?
The winxp grub menu entry is:
The output of fdisk -l is:
