This is very interesting. You have correctly assumed what
fdisk shows as most of my partitions, and /dev/hda6 is the
Mepis installation. What I find interesting is that Ubuntu
decided that /dev/hda5 was Hd0,4 and Mepis gave /dev/hda6
as Hd0,5. At least, they offered me those for the Grub
config to go on the Mbr. Why, I wonder, should two distros
make a similar error.

I've been making some progress in creating Grub boot disks,
and now Debian-User has put me onto a package in Debian
(and therefore in Ubuntu) called 'Grub-disk' which can be
unpacked (it's zipped) and put onto a floppy. It provides
a Grub menu with some examples which can be edited to the
correct requirements and offers the option of a Mbr install.

I'll try with your amendments to see if I can boot Ubuntu
and Mepis and then have a go at using its Mbr installation
option.

Thanks for your interest and response.

Regards,

John.
