GRUB problem

KamiKazi

Hey all,

Trying to install Linux Mint 8 at the moment, but I can't seem to set up GRUB properly.

I've three hard drives:
320gb - Mint installed here with 10gb swap area
400gb - Media drive
500gb - Empty.

All drives are in Ext4 format, here's the fdisk output:

Disk /dev/sda: 320.1 GB, 320072933376 bytes
255 heads, 63 sectors/track, 38913 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk identifier: 0x9d769d76

   Device Boot      Start         End      Blocks   Id  System
/dev/sda1   *           1       38161   306528201   83  Linux
/dev/sda2           38162       38913     6040440    5  Extended
/dev/sda5           38162       38913     6040408+  82  Linux swap / Solaris

Disk /dev/sdb: 500.1 GB, 500107862016 bytes
255 heads, 63 sectors/track, 60801 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk identifier: 0x06f506f5

   Device Boot      Start         End      Blocks   Id  System
/dev/sdb1               1       60801   488384001   83  Linux

Disk /dev/sdc: 400.1 GB, 400088457216 bytes
255 heads, 63 sectors/track, 48641 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk identifier: 0x6daa4dac

   Device Boot      Start         End      Blocks   Id  System
/dev/sdc1               1       48641   390708801   83  Linux

So when it boots up it goes through BIOS, loads GRUB and outputs 'no such disc'.

Can someone tell me how to set up GRUB to point to the Mint installation?

Thanks.

You need a fairly new version of grub to boot off ext4 IIRC.

what does your /boot/grub/menu.lst file contain?

I think it's Grub2 I have, as there's no menu.lst but there is a grub.cfg

Are you sure the BIOS is set to boot from the correct hard drive?

Other than that, maybe you can find the answer by trawling through the Ubuntu documentation:

Don't feel bad, I googled a bit and saw that a few other people did the same thing.
