Error 15 after upgrade -

[von Stalhein]

I saved my entire semi-borked 9.10 installation to an external hdd and prepared to do a clean install of Karmic.

I used the alternate cd to do the install, as any system boot with the desktop version resulted in a "cannot read this video mode" situation.

The OS installed OK (AFAIK), but on reboot I got the dreaded "Error 15".

I still can't use the karmic CD as a live CD, but I can get into it via good old 9.04.

My fstab:

# /etc/fstab: static file system information.
#
# Use 'blkid -o value -s UUID' to print the universally unique identifier
# for a device; this may be used with UUID= as a more robust way to name
# devices that works even if disks are added and removed. See fstab(5).

insmod gfxterm
insmod vbe

Output of blkid is

/dev/sda5: UUID="A83CB1173CB0E18C" LABEL="Disk 2" TYPE="ntfs"
/dev/sdb1: UUID="01C3D871F965AC80" LABEL="DSK1_VOL1" TYPE="ntfs"

/dev/sdc5: TYPE="swap" UUID="27179ee5-e990-4dcb-9fc8-a5857a0f1b37"

As you can see, the system has 3 HDDs, sdb1 and sda5 are XP OS and data respectively, and used to dual boot with Jaunty.

Where to from here??? :frown:

I have gotten a similar result. I have a Ubuntu-only server with the boot sector on /dev/sdc1. I get the dreaded Error 15 after a clean install and am ready to go back to Jaunty. I've tried the "rescue a broken system" to make sure that the boot sector is on sdc1. When I look at the grub.cfg file, I get a UUID which corresponds to the UUID of sdc1 reported by blkid. Does anybody have an idea what is going on? Is Karmic totally broken?

Mine was the same until the re-install of GRUB 2, and it then started to behave.

My only issue now is that I can't get it to dual -boot XP.
