Might it be possible for two or more distros to share the same boot partition?
I guess getting it all on there might be a bit tricky.
Let's say you install #1 and backup /boot
then install #2 and use the same /boot different / and leave #1 partitions intact.
then put the files for #1 back into /boot and setup grub or lilo.
I don't know what this has to do with the 1024 thing but this made me think of it.
Anyway for the final answer
Install grub and put whatever you want, wherever you want.
Unless your bios does not support LBA
It does don't it?
If not get nuni you can put it on and boot anything without the bios. It will access any harddrive anywhere, directly regardless of what the bios might think.
