GRUB Multiple boot

[alex]

For what it's worth to those concerned with GRUB dual boot .......

.I have two Windows XPs installed on hda1 and hdb1,  two UBUNTUs on hda5
and hda10,  two KNOPPIX on  hda7 and hdb 7, Suse on hda3,  Libranet on
hda6, JAMD on hda9, and Progeny 2 on hda8.  I have been unsuccessful in
installing an old version of Lycoris.
Why do I have all these linuxes?       Don't ask!!!!  I'll just say
UBUNTU is my favorite.but I'm so entrenched in email in ONE of the
Windows that it's difficult to switch it to UBUNTU

Each of the linuxes has an identical  /boot/grub/menu.lst.  At the
moment, one of the UBUNTUs has the default grub. If, for some reason, I
want change the default grub boot to a different linux, I boot that
linux and issue the command  'grub-install  /dev/hda'   (or hdb). It's
important to keep notes of which linux has the default grub.      .

In addition, the two Windows, boot from the MS booter that is created
when a second Windows is installed and this booter in turn appears in
the GRUB menu.as a single boot item.

The trick here is to choose GRUB BOOT as each new linux is installed and
then edit its /boot/grub/menu.lst to include all the other linuxes plus
the dual Windows boot. The new linux will automatically  have the
default GRUB but it can be transferred to a different linux if desired..
If an installation doesn't offer GRUB boot, it can be created with an
editor by copying it from another installation.  It's a good idea to
have a copy of GRUB on a floppy or CD so you can construct it in an
installation that doesn't have it.

Just to show how /boot/grub/menu.lst looks with all these systems on the
menu, I'm including a copy of mine.  There are several # to disable
lines and previously installed systems..
Perhaps you might want to copy and modify it for your partition scheme.
