Yes. That is the way I install all distributions.
1. Install a minimal small distribution which uses grub, without X.
The only purpose is to put its grub into the MBR and serve as the
2. Install all other distributions with putting their bootloader into
their respective root partition
3. Enter the installations into the menu.lst of the steering center's grub with
title <distributiion name>
Here the bootloader of the distribution to start lies in /dev/sda5
The advantage of this way is not only that you can install
distributions with different bootloaders. Whenever you install a new
kernel in any of these distributions you have to do nothing extra
because the new kernel is set in the distribution's bootloader, not in
the master boot loader.
