a better solution

I got this error after installing the Ubuntu 7.10 release candidate.

The error usually happens because Linux and your BIOS detect your hard 
disks in different orders. GRUB tries to translate between the two using 
the device.map file in /boot/grub/device.map, which is automatically 
generated. Chances are, it guessed wrong.

In my case, I have three SATA hard disks.

My BIOS sees them as:
HDD1 - 80 GB - Windows
HDD2 - 80 GB - Linux
HDD3 - 250 GB - Media

Linux sees them as:
/dev/sda - 80 GB - Windows
/dev/sdb - 250 GB - Media
/dev/sdc - 80 GB - Linux

So it generated device.map assuming that order was correct, i.e.:
(hd0) /dev/sda
(hd1) /dev/sdb
(hd2) /dev/sdc

When the installer installed GRUB using that data, it tried to install 
the first part of GRUB on /dev/sda and told it to look for the OS on 
/dev/sdc. Unfortunately, this translated to "install on (hd0) then look 
for the OS on (hd2)", so it was looking for the OS on the wrong drive.

To fix it, you have to teach GRUB which order the BIOS uses. To do this, 
follow these steps:

1) Boot from the Ubuntu CD
2) Open a Terminal (Applications->Accessories->Terminal)
3) Run "sudo -s"
4) Run "mkdir /ubuntu"
5) Run "mount /dev/sdc1 /ubuntu" (where /dev/sdc1 is your Linux root 
partition)
6) Run "chroot /ubuntu"
7) Run "cd /boot/grub"
Edit device.map (using vi or another text editor)

In my case, my new device.map was:
(hd0) /dev/sda
(hd1) /dev/sdc
(hd2) /dev/sdb

which told GRUB that sdc was really the second hard drive, not the third.

9) Run "grub --device.map=device.map"
10) Type "root (hd1,0)" (where hd1,0 is your Linux boot or root 
partition using the BIOS order)
11) Type "setup (hd0)" (where hd0 is your first boot drive, almost 
always hd0)

You should see a message that it's now telling GRUB to load 17+(hd1,0) 
instead of 17+(hd2,0) or something like that. This is what we want.

12) Edit menu.lst

You need to change references from (hd2,0) to (hd1,0), or whatever your 
Linux boot drive was autodetected as to whatever it is according to your 
BIOS.

If you get this step wrong, you'll see an error message something like:
Error 17: Cannot mount selected partition

meaning it's looking for a Linux file system on that partition, but it 
can't find one (because the drive device number is wrong in menu.lst).

13) Reboot
