grub fill wrong number for s-ata harddisk in menu.lst file

[ibuntu]

Binary package hint: grub

My harddisk's interface is s-ata. I install ubuntu 6.06.1 LTS in my harddisk successfully. But the grub fill wrong number for init files in menu.lst . So I cannot load any OS.

I load my computer with live CD, check the /boot/grub/menu.lst file, found all init file be located in (hd1) harddisk. Since my computer only installed on harddisk. So I change all (hd1,X) to (hd0,X). I load my computer with ubuntu after modify.

this right config
title Ubuntu, kernel 2.6.15-27-k7
root (hd0,6)
kernel /vmlinuz-2.6.15-27-k7 root=/dev/sda8 ro quiet splash
initrd /initrd.img-2.6.15-27-k7
savedefault
boot

the following is created by grub automatically.
title Ubuntu, kernel 2.6.15-27-k7
root (hd1,6)
kernel /vmlinuz-2.6.15-27-k7 root=/dev/sda8 ro quiet splash
initrd /initrd.img-2.6.15-27-k7
savedefault
boot
