This post is two fold
The first: Partitioning
I love Fedora but I would like to try out different distro's as well. I am having a difficult time with partitioning my HD. Only 3 primary (or logical) partitions seem to be allowed. I set up a /boot & swap partition only to find that I have a partition left for one OS. Can multiple distros use the same /boot & swap? Can I set up one extended partition with multiple partitions inside of it for multiple OS's? Maybe that's why LVM should be used, this way swap and / can be on one partition.
The second: GRUB
I also have questions with GRUB. If I install another OS it will overwrite the GRUB that was there and will not allow me to boot the first OS it until I add the entry in the new GRUB. How do I know what entries to add if the GRUB gets over written? Then I will need to figure out the old grub entry and change it every time the kernel for that OS gets updated. I have been reading some posts that suggest that Ubuntu likes to be on the MBR. Can I use the GRUB from Ubuntu on the MBR to chainload to other GRUB's? If GRUB is used as a secondary boot loader and is written to the first section of the /boot will other distro's overwrite it when they are installed as secondary bootloaders as well?
Is it possible to do this with one HD? If so how should partitions be set up? What is the easiest way to multi-boot (GRUB) different Linux distros?
I have no idea why I feel the need to have abuncha OS's on my box. I love to be frustrated I guess.
