Grub error 15

Postby ae0000 on Sun Jul 20, 2008 9:52 pm

Hello all,

I downloaded a copy of Elyssa on the weekend to install over the top of a buggy ubuntu hardy install. The install appeared to work fine, installing root to sdb1, however on rebooting I received a grub error 15 (file not found).

I checked out the wiki and edited menu.1st to use UUID's however this did not solve the problem. There are no other OS's on this system. I have tried to reinstall twice. There is another harddrive (sata) installed at sda. And in case it matters, /home is installed at sdb2.

I haven't had a chance to investigate further, but thought that I would check here to see if anyone else had the same problem and had solved it (and hence will save me some time :)

Cheers

Andrew

Boot the live CD and then post the output of
Code: Select all
sudo fdisk -l
from a terminal. Also post your /boot/grub/menu.lst from Mint's partition.

Sdb seems to be a secondary drive. Sda should be the master. You won't be able to install Mint's grub to sdb and boot it directly. Is there an OS on sda?

Oh :)

I can refiddle with the drives and make sdb master etc.

Its strange because ubuntu installed fine on this setup.. i would have thought mint used the same process.

thanks for the pointer. I'll sort it out :)

Cheers

I didn't mean you had to move the drive order. I was just trying to make sure I understood the drive order. The point I was going to make was if sda was the master drive, then the PC will try to boot from it first, and there is no link to the second drive(sdb) where Mint/grub is installed. The master drive that the PC automatically boots to first is the gateway to all the drives connected. What distro is on sda?

In that case, it would probably be easier for you to switch the drive order in the bios settings and do a quick reinstall of Mint on sdb.

i swapped the two sata cables around and reinstalled and it worked :)

thanks for all your help.

i was thinking when reinstalling, 9 out of 10 times i install linux, i always need to add 'noapic' to the live cd. i'm assuming this must happen to a lot of other people too. it would be cool if at the point where the livecd says " failed to boot, try adding noapic to your boot command " it restarted the whole process with noapic included (with some kind of obvious message to the user). i realise this is not a mint specific thing (kernal?? or upstream in debian land??), but it would be cool.
