can't boot anymore /dev/hdb -> /dev/hde

Hi there,

The mainboard of my computer died, so I purchased a new one. Now, when I'm trying to boot my Suse 9.1, it doesn't work. Grub keeps looking for /dev/hdb7, on which my Suse is installed, but that hard disk is detected as /dev/hdf. How can I solve this?

Some more details:
Distro: Suse 9.1 Pro.
I have dual boot with WinXP. WinXP is installed on the master disk of the primary IDE controller.
Suse is installed on the slave disk of the primary IDE controller.
The secondary IDE controller has a DVD writer (master) and CDRom player (slave). At first the setup was as following:
Primary IDE, master --> /dev/hda
Primary IDE, slave --> /dev/hdb
Secondary IDE, master --> /dev/hdc
Secondary IDE, slave --> /dev/hdb

Now the devices get detected as:
Primary IDE, master --> /dev/hde
Primary IDE, slave --> /dev/hdf
Secondary IDE, master --> /dev/hdg
Secondary IDE, slave --> /dev/hdh

How can I change this back? The only difference on the mainboard (ASUS A7V600-X) is that this mainboard has SATA support, but I disabled that in the BIOS because I don't have any SATA devices (yet).

If the device is being recognised as hdf then that is what you need to use.

Use the recover option from the SuSE installation CD and it should make all the necessary changes for you.

Worst case scenario is a complete reinstallation.

Boot from the recovery CD and make changes to the GRUB config file.

Just replace references to /dev/hdbx to /dev/hdfx

reboot, enjoy.

I would also make sure that any BIOS RAID settings were also disabled.

Thanks for your reply everybody.

I can boot from CD, but I don't know where to go from there.

The options you have given me say that I have to keep the drives as /dev/hde and /dev/hdf. I'm not really happy about that. What happens to fstab? My configuration settings in mplayer and k3b?
I would really have them back as /dev/hda and /dev/hdb.

During the boot process 4 IDE controller are detected. How is that possible? There are only 2 and the sata is disabled in the bios.

Michaelk, you said that my BIOS raid settings should also be disabled. But there isn't a single setting in the bios regarding raid. Could you please clarify?
