well, my good friend has a pretty beastly laptop, god knows how much memory is on this thing but he has windows xp OS, mac OS and linux OS all on it
eek dont know what versions they are though
he has a seperate startup screen to allow him to choose which system to run
xd took him like 2 month to finish it XD
Which means he has LFS?
confused 'Cause, you know, I have stood next to an Ubuntu installation and I can certify this s**t installs in 10 minutes plus maybe another 10 minutes to configure the GRUB (the startup screen) and other stuff.
Though the fact that he has Mac OS makes it different... Mac OS is not designed to run on an IBM PC architecture even though it's Intel x86-compatible, which means you have to do some weirdo hackwork in order to get it to work on a non-Mac machine.
