Can I boot 4 different OSs?
 

Can you only dual boot, or is it possible to set up a bootloader to boot any of four (4) different Linux distros (on two different HDDs)? Why would I want to do this?....I have purchased two distros, Mandriva 2006.0 and SuSE 10.1, in the past and found that there are things I don't like about each. I would also like to try Debian (Sarge) and Kubuntu and, in the process, be able to compare all four. What I really want to do is get away from Win XP as fast as possible. I have searched LQ on multiple boots and have only found dual boot................ReaderRat

Sure.
Both GRUB and LILO will do just fine.
It's really just the same as with a dual-boot system.

I have written some notes Here about multi-booting linux.

Just install the distros, one after the other, and you shouldn't have any problems.

I suggest that you create a separate partition for your documents (mount it at /data), and then create a link in your home directory to /data. This way, your data is always easily available whatever distro you are using and you avoid any conflicts that can arise by simply sharing /home.

I hope this helps

You can definitely set up a multi-boot system with 2, 3, 4, 10, or however many operating systems you want -- the main limitation is disk space. That said, realistically it would be hard to imagine the practical value of having more than maybe 3 or 4. I believe the record is something like 80 different distros, but that's pretty much useless, as most of your time would be spent rebooting (assuming that each distro got equal usage, and if not, there'd be no real point in intalling it)

In any event, a pretty good article on multi-booting is: http://www.smartcomputing.com/Editor...5w02/05w02.asp

Just being annoying...:
The main limitation is not the disk space but the amount of partitions a kernel can read ;)

PS: This is not the same for every drive.
Some hardware limitations will not always allow your kernel to read as much partitions as it could...
