** Summary changed:
- system unbootable due to old BIOS
+ old bios needs /boot partition on large disk
** Description changed:
- 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.)
-
- Possible solutions:
-
- * 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)
+ Older bios can not access the entirety of new large disks. The
+ workaround to this is to create a /boot partition ( 100-200mb should do
+ it ) near the start of the disk. It has been suggested that the
+ installer do this by default, but this has been rejected due to it
+ complicating the already fragile dos partitioning scheme and not being
+ needed for the vast majority of people.
** Changed in: grub-installer (Ubuntu)
Status: Incomplete => Won't Fix
