Dual boot problem - Ubuntu 12. 04 - opensuse 12.1

**rich paul fox** · 08-31-2012

Hello
I have at /devhe problem that I have ubuntu 12.04 installed on my laptop hard drive and I have tried installing opensuse 12.1 to a usb disk drive.

On booting the grub menu gives me:

Ubuntu, with Linux 3.2.0-30-generic (recovery mode)
Previous Linux versions
Memory test (memtest86+)
Memory test (memtest86+, serial console 115200
openSUSE 12.1 (on /dev/sdb1)
Failsafe -- openSUSE 12.1 (on /dev/sdb1)

I can load ubuntu but not openSUSE.

When I select openSUSE I get the following message:

error: no such device: d9d5081a-ccdc-4f8a-beab-e69554438dad

error: no such disk

error: you need to load the kernel first,

It's trying to boot a partition by uuid which is what the above is and can't find it. Maybe because it no longer exists? Boot Ubuntu and open a terminal and run this: sudo blkid.
See if you have a partition with the above uuid and see what it is.
The grub.cfg file you posted doesn't have any menuentries so I don't know how anything boots? Unless that's the wrong one or not complete? Where did you install the bootloader for Opensuse? To the / of the opensuse system? the master boot record of the external usb? You might try running sudo os-prober and sudo update-grub in Ubuntu. If that doesn't work, you can get a lot of information on drives/partitions and boot files by going to the site below and reading the instructions, downloading and running the bootinfoscript. If you can't resolve the problem, post the bootinfoscript results.txt file here.

Thanks for your reply yancek I am trying to gather more info about boot partitions but my knowledge is still somewhat limited, I have tried using disk utilitily which gives what seems pertinent info but I am unable to copy this info but from what I can make out the boot root is in it's own partition.

I have run blkid and this is the output:

Code:

richard@richard-VGN-NR21M-S:~$ sudo blkid

Sorry, try again.

Output from os-prober:

Output from upgate-grub:

Below is some other info I have gained - but I do not know if it is of any use for this problem.

I will now restart my system and see If I can boot openSUSE.

Again Thanks for your help.

[QUOTEI will now restart my system and see If I can boot openSUSE.
][/QUOTE]

Good luck with it. I see that the uuid that was shown as not found is in the output of the blkid command. Without the contents of the grub.cfg file, it's difficult to do more than guess what the problem might be. For future use, you might take a look at the bootinfoscript even when you don't have problems. Downloading and running and saving the output file gives a lot of useful information for drives/partitions and boot files that can come in handy at times.

**rich paul fox** · 09-02-2012

Thanks again yancek

I have now downloaded and ran boot info script wich gave the following output:

I am in the process of studying this output - not sure how much I will make sense of - part of reason I am trying to do this is as a learning excercise.

Again thanks for your help.

I don't see any real problem. Opensuse is on sdb1, the uuid entry in grub.cfg compares correctly with the output of the blkid command. You might try putting a chainloader command in the Ubuntu grub.cfg for Opensuse, can't really see anything else to suggest:

menuentry "Opensuse 12.1 {
insmod part_msdos
insmod ext2
set root='(/dev/sdb,msdos1)'
search --no-floppy --fs-uuid --set=root d9d5081a-ccdc-4f8a-beab-e69554438dad
chainloader +1
}

Letting Opensuse boot itself might work but I don't really know, nothing else I can think of to try?
