Are you sure you're selecting the correct disk? Don't just assume |
| 27 |
since it's hdc in Linux it's hd2, use tab-completion when you're |
| 28 |
setting up grub., Have you tried using grub console |
| 29 |
w/tab-completion? Hit 'c' when you're booted to grub, and try |
| 30 |
|
| 31 |
grub> root (hd {hit tab to see what's there} |
| 32 |
It's all the same syntax as grub.conf |

Where is grub installed currently? The easiest way I've gotten it to |
| 40 |
work is to install over Window's MBR and use a chainloader +1 line to |
| 41 |
chainload windows. |
| 42 |
|
| 43 |
|
| 44 |
Lastly What partitions are marked as active/bootable? I assume the xp |
| 45 |
one is (hda), but what about hdc when you're trying to install grub |
| 46 |
there? Also, I don't _think_ you can have more than 1 active/bootable |
| 47 |
disk. |

| 52 |
Again, this leads me to believe that grub is seeing the second disk as |
| 53 |
hd1. Granted; you never said what you called it but that might be your |
| 54 |
problem. |
