multi boot distroses
When you add multiple distroses, use SuSE's Grub. Fedora and Mandrake both have a bug when adding new info to the Grub file with multi distrosses. Or you can edit the Grub manually in Fedora or Mandrake to override the bug depending on whose Grub bootloader you use.
I installed SuSE, Redhat and Mandrake on 3 different partitions using one swap file. After several attempts, I decided to install SuSE last so I could use SuSE's Grub file to boot Redhat and Mandrake.
I first installed say Redhat on hda5 and allowed it to create a grub file. At that point I retrieved the boot info from the Grub file because you need that info to add it to the final distros.
I then installed Mandrake on hda6 and allowed mandrake's grub file to over write Redhats grub bootloader. I then retrieved the boot info for Mandrake for the same reason. You need that info to add it to your final grub file.
I then installed SuSE on hda7 and allowed SuSE's Grub file to write over Mandrakes grub file. I then booted into SuSE and added the boot info that I retrieved from Redhad and Mandrake into SuSE's Grub config file using the GUI.
Now you should be able to boot to your desired distroses.
I will add a note of recommendations.
I abandoned this multi-boot of distroses from different partitions because I found that one effects the other in some way or another. For example, if I made changes (specific changes which I do not want to get into) to Mandrake or Fedora, than SuSE would no longer boot. SuSE's boot does several checks and if some of those checks are no longer valid, SuSE is designed not to boot. It goes into a Kernel panic (same with the others). I eventually got feed up with re-installs.
There is a better way. I am going to pick up a couple of cheap drives (4 GB) and install one distro on each drive so they can boot from there own Grub file. That way, one distros doesn't cause problems for another when you make alterations. I will change them with a drive rack.
I did learn a bit from trial and error. I finally settled with Fedora.
