Suddenly I cannot boot into 10.1 with GRUB coming up with, "Error 18" as
soon as it starts to execute on bootup.
Does anyone know what this error means and how to get grub working
correctly again?
info grub, Troubleshooting, Stage2 errors:

Create a separate /boot partition somewhere near the begingining of your
hard disk.
Thanks for the response but, eh, I have been dual-booting for years now
and therefore already have a 300MB boot partition at the start of the
HD, and have been running 10.1 without any problems since it came out
until this morning when the error message suddenly came up. (Just
checked with cfdisk and all the partitions are there as they are
supposed to be.)
Checked in the BIOS and all drives are correctly recognised.
Any other suggestions, please?
Thanks for your help. The results:
Can you view the menu.lst file at the grub prompt(grub>) and do the entries
match your current partitioning setup?
grub> cat (hd0,0)/boot/grub/menu.lst
Yes.
where (hd0,0) represents (drive#,partition#) with numbering starting at zero
and pointing to the partition holding menu.lst which should be your separate
boot partition assuming grub was installed there originally and not to the
root partition. (hd0,0) would point to the 1st partition on the 1st drive.
(hd1,3) would point to the 4th partition on the second drive, etc...
grub> geometry (hdx)
will show existing partitions(x=0,1,2 etc.) .
Geometry OK. All partitions correctly shown (both HDs, btw).
Can you boot from the grub prompt manually?
ie.
grub> root (hdx,x)
This is OK.
grub> kernel /vmlinuz root=/dev/hdx <other options>
This is OK.
grub> initrd /initrd
This comes up with an error, "Error 28: Selected item cannot fit into
memory" which is a bit strange as I have 1.5GB of RAM and even right at
the moment I have 58.5MB free.
grub> boot
Of course this does not happen :-) .
What does all of the above mean? Do I need a grease and oil change or a
new set of spark plugs? :-)
Cheers.
