Installer misconfigures grup (grub) with scsi and ide devices

[Wladston Viana]

Steps to reproduce:
1.Install an IDE HD at first IDE slot
2. Install an SATA HD at first SCSI slot
3. Install ubuntu on the SATA drive via the Live-CD

Grub will have, in device.map
(hd0) /dev/hda
(hd1) /dev/sda

and grub will try to load from hd0, where Ubuntu is not installed.

To fix that, I had to manually edit the boot/grub/menu.lst file, changing hd1(the ide one) with hd0(the sata one).

thank you for your bug report. which ubuntu version did you try (dapper? edgy?) and which CD version (DesktopCD?, AlternativeCD?)?

[Wladston Viana (wladston)]

It is a Dapper DesktopCD. If any other info is needed, please let me know!

I can confirm this:

Asus P5K-VM, Ubuntu 7.04, SATA HDD, PATA DVDRW, Core2 Duo E6750.
Installed ubuntu from a live CD on this new machine.

PROBLEM: Installs fine from bootable CD. Freezes (at splash) when starting up though. Just after loading/mounting SATA modules.

I don't think this is specific to Core2duo, but Story 17 on https://wiki.ubuntu.com/Core_2_Duo_Support gave me the solution.

FIX: Grub creates the incorrect entry for root, It was "root=/dev/hda1", but it must be "root=/dev/sda1"!
That fixes the problem on my board!

Running "uname -a" once in Ubuntu, gives: "Linux def-desktop 2.6.20-15-generic #2 SMP Sun Apr 15 07:36:31 UTC 2007 i686 GNU/Linux "

This is a show stopper on my setup. As I couldn't do anything until I edited the grub menu entry.

Hi,
Just wondering, is this being worked on?
It's a major issue, as it makes Ubuntu uninstallable on a brand new PC with a standard SATA HDD and PATA DVDRW.

David,

Probably you can do just as I did - after you have installed ubuntu, load the live cd, locate /boot/device.map, change the bits there as needed, and restart...

[David Freitas (jddcef)]

Thank Wladston, That does fix the problem yes, but the cause of the problem still has to be fixed so that other users of Ubuntu aren't deterred from using Ubuntu because it doesn't boot up.

The easiest way to start a system like this is to press "e" to edit the grub line, and change the /dev/hda1 to /dev/sda1, and then press "b" to boot the grub entry. That boots it OK, but the change isn't permanent. You can then edit /boot/grub/menu.lst to make the change permanent (as root)

My /boot/device.map contains just this line (which I haven't changed):
-------------------
(hd0) /dev/sda
------------------
That doesn't seem to work like that.

I will try get hold of Gutsy Ubuntu from my University soon. To test if it is fixed.
