Hello,

Thank you in advance.
I was running Suse 10 and just added Debian 3.1 to multiboot.
I can boot to Suse just fine however, when I try to boot to newly installed Debian, I get:

Grub Error 18: Selected cylinder exceeds maximum supported by BIOS
root (hd0,2)
Filesystem type is ext2fs, partition type 0x83
kernel /boot/vmlinz-2.6.8-2-386 root =/dev/hda3 ro

Here's fdisk output:
Disk /dev/hda: 160.0 GB, 160041885696 bytes
255 heads, 63 sectors/track, 19457 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

Here's the menu.lst:
