Quote - Colin Watson's post from this site
I ran the Warty Warthog installer on an older computer, a Super 7 motherboard
with a K6-III processor. I believe the BIOS was the problem. The hard disk is
a 20 GB disk, and the BIOS pre-dates disks that large.
The installation ran to completion, and then the system would not boot. GRUB
returned the terse message "Error 18".
I Googled for "GRUB Error 18" and what I found suggested that it was a problem
with the BIOS accessing deeply into the hard disk. I re-ran the installer, and
this time manually partitioned the hard disk, with the very first partition a
small "/boot" partition for GRUB and the kernel.
The installation ran to completion and the system booted up just fine. (By the
way, a K6-III/450 with 384MB of RAM makes a pretty nice Ubuntu system.)
* make the standard disk configuration have a /boot partition
* detect an old BIOS, and if detected create a /boot
* don't change the installer, but put documentation in the README (not ideal,
but the least amount of work)
I took this on board and created the following partitions on my compaq armada lappy e500 from the Kubuntu 6.06.1 install.
#hda1 /boot 100MB b
#hda2 / 8GB
#hda3 300MB swap
#hda5 /data 21GB
Grub boots the kernal from the boot partition and fires up the "hda2" files without problems. I even wnet to the chore of installing a new bios to fix the issue but it didnt help.
Hopefully this solves some of everyones problems. It saved me twice!!
Sadly this'll mean you'll have to run the install again but it *should* work. And im doing the same thing on another lappy right now.....
