Some hints:
(I'm speaking in general and on a Mactel, on older computers, on a PC, it may be different, especially for the memory/disk handling)
- Dual boot OS X/linux is not difficult to make, as long as you use rEFIt (I have not tried on one of my PPC mac)
- Don't try a triple boot (OS X and 2 linux flavour) at first, it's not as smooth, I'm still working on this one.
- there's plenty of How-to for triple boot OS X/Windows/linux, read them.
- back up ! I have never had an issue playing around between linux and OS X. but it can happen. It's playing with partition maps, bootloaders and the like.
Choosing a Linux :
- there's a lot of distributions around, some are heavier, lighter, simpler… I've only tried Fedora (under GNOME and KDE) and Ubuntu Studio. Fedora because it's elegant (especially for install) and it works perfectly with the CCRMA packages. Ubuntu Studio as it is dedicated to creation though the installation is more "east german", you should RTFM a little before trying to install Ubuntu IMHO.
On the partitions for linux :
- Your disk for OS X to boot has 2 partitions you'll see in partitioning tools under linux. DON'T TOUCH THEM (or resize the main OS X partition with the boot camp utility, nothing else, and back up beforehand).
- Whatever linux flavour you'll try, it can go on one partition, but a better practice is to separate a few things just in case.
- the minimum partitions you should make are :
- /boot (the bootloading zone) The size depends of the distribution. Fedora needs 500 MB or more, which is a lot.
- / (where the system and apps will be installed, you can pile some GB, 10 is a minimum (you can use less but it stupid to lack estate…)
- /home (where are the users, it makes switching of "flavor", reinstallling linux way easier, pile some GB)
- swap (well, for virtual memory, it's very efficient so you don't need a lot of GB that usually you won't use, but to save RAM to disk you must have at least the size of the your RAM… If you don't need this feature, you can be less generous.
There's over repertories that can be "separated" into partitions, but it needs special uses (like at least 2 linux flavours around, or that you know exactly the estate you need for the software only).
During Installation :
- For the keyboard, select your country, and a layout, don't waste your time searching as the mac layouts are not available (during the install)
- once it's over, you'll be able to switch to Apple/laptop (my case) or the relevant for you.
- Hence, keep to Latin1 or Latin9 for installation, and don't try to use exotic types, keep to basic letters and punctuation.
- Have some ethernet connection to the Net, you'll need it.
Once done with the installation, eject the CD or DVD (it should do so by itself). When rEFIt shows up on start up, select the partition utility and say "yes", and start up in OX S. Once booted in OS X, shut down, and choose your linux this time, it'll boot.
Right after :
- update !
