At the fist, I would say that I am going to tri boot my hard disk with the following distributions:
openSUSE 12.1 (x86_64) / 64 bit OS
Ubuntu LTS 10.04 (i386) / 32 bit OS
Fedora 15 (x86_64) / 64 bit OS
Said that, I have already taken the full back. Other details are as follows:
Hard disk size = 250 GB
RAM = 2 GB
Processor: Supports 64 bit
Now to play with the hard disk, I am going to install the above said three distributions. Well the queries are as follows:
I read at google: "You have a "primary" grub in the MBR, controlled by one (exactly one) distribution, which has that distribution's kernel entries. in addition, you have chainload entries, which point to the grub boot code in the boot partitions of other distribution installations."
Does it mean that I should have a separate /boot partition with the first installing distribution (openSUSE in my case)...? How do I install these three?
I should make separate /home, /boot and /swap for each partition? Or only separate /swap for each partition...?
Whatever be the case, I know that there can be at most 3 primary partition - /root (openSUSE) /boot (openSUSE) /swap (openSUSE) and all other in the extended partitions, that is okay, but in the extened too, should I make separate partitions for each (/swap, /boot, /root, /home) of each distribution...?
And finally, how would the bootloader work in this scenario...?
