Problems clearing ERROR 15 from grub
Hi-
I've tried to solve this on my own but am running into issues. I am using Ubuntu 10.10 dual booted with windows vista. My boot is in a separate partition (sda5). My computer told me that there was limited space on that partition so I tried to clean things up using apt-get by removing old kernels. Turns out I didn't do it correctly because I consistently get an 'ERROR 15' when I shut down and rebooted my computer. I have a live-CD USB-stick so I tried reinstalling grub, (grub-install) updating the menu.lst (update-grub), and manually going through menu.lst and changing to root=(hd0,4) and groot=/dev/sda6 but I still get this ERROR 15 when I reboot. when I do sudo grub find /boot/grub/stage1 find /boot/stage1 both give me an ERROR 15 message and I'm not sure how to proceed with a diagnosis. When I ran update-grub, occasionally it used to tell me that /etc/fstab may be incorrect but (1) it doesnt tell me that anymore and (2) I dont know how to fix fstab Here is fstab Code:
# /etc/fstab: static file system information. Code:
title Ubuntu 10.10, kernel 2.6.35-27-generic Code:
root@ubuntu:/# ls /boot/grub/ Code:
grub> find /boot/grub/stage1 |
Ubuntu10.10 uses grub2. Do you have cd?

I think that Error 15 means "Can't find bootable Image"
Does Code:
update-grub And, as Eddy1 above, Ubuntu 10.10 uses Grub2. Try googling "Grub2 Ubuntu", there's a very good "howto" sort of page among the Ubuntu Info. Play Bonny! :hattip: |
Hi
Thanks for all your replies. After I wrote that, ( I was on ubuntu through the live-CD) I rebooted and everything magically worked. :/ My (uneducated) guess is that the reboot before that I had tried to do grub-install, but I did not do update-grub. That had the effect that I couldn't even get the error-15 error and I had to restore a menu.lst that I had saved. I'm not sure, but I think it was looking for "hda" when all my partitions are "sda". When I rebooted, wrote this message on this forum, I did update-grub and grub-install and allowed them to rewrite anything they wanted (namely menu.lst). I also used this command Code:
sudo mount -o bind /dev /mnt/root/dev (basically from here : http://ubuntuforums.org/showthread.php?t=224351) Something about this worked. Again, thanks all. |
If solved mark as solved so others who are experiencing same problem can find answer to their problem.

Very useful! Now in my "Linux Log Book," It's allowed me to recover my Ubuntu 10.10 desktop and hopefully gain access to my other installed Distros; Fedora 15 and Centos 5. Installing the latter overwrote the MBR in the first place. Cheers ED! Play Bonny! :hattip: |
