Grub error 15 on boot (SW 10.2)
 

I have just installed slackware 10.2 and when i rebooted i got a grub error 15 on boot..

i have checked and people say that it can be caused by a mismatch between the partitions and how they are displayed in /etc/grub.conf
but i cant find such a file on my Hard drive anywhere
either by the name grub.conf or menu.lst

what would be the next thing to try?

Error 15, I belive, is saying that it can't find a needed file. What the file is, I'm not overly sure. Your config file for grub is /boot/grub/menu.lst not /etc/grub.conf.....

Do you have a /boot/grub folder, and if so, what are it's contents?

I have had the same message after installing Slackware to a external USB drive and after trying to boot from the external drive. I choosed the wrong harddisk number for "root". I could repair it.

Try to boot with a Live CD (I used an old Slackware 9.1 CD (2)) and type as root in a terminal:

mount --bind /dev /mnt/where_your_root_partition_is_mounted/dev
chroot /mnt/where_your_root_partition_is_mounted
grub --recheck
root (hd0,x) <-- x is your root partition
setup (hd0,0)
exit

After a reboot it should be o. k..

Just try it and may be you are also successful ...

Fluxx.

seems not... any other places it might be?

will try flaxes idea, (i can boot fully with a boot disk (how i am typing this) so i will try in konsole)

if you coudl post taht again...fluxx with the breaks between comands better difined as i seem to be having trouble working out where one comand ends and the next beginns

Try run grub-install /dev/hda as root
(assuming your drive is hda)

Then configure /boot/grub/menu.lst
