. If you are going to dual (and especially tri) boot, then you need to give careful consideration to your partitioning scheme. . I like to use at least 20GB (8GB is the absolute minimum, IMNSHO) for WinXP with a large partition for data files. If you install a lot of big apps, you may want to go to 30GB or more. I change My Documents, and all apps that allow me to, to point to the data partition. That way, if WinXP has to be re-installed, my data is still there. . Most of the newer versions of Linux will handle NTFS out-of-the-box (or an easy tweak), so you can use the same data partition - just mount it. That way you can make the Linux OS partitions smaller. . Unless you have an app to repartition w/o losing data, you'll probably be better off wiping the HDD, partition, install WinXP first (as per LinuxH4x0r; I've heard the same thing about XP "losing" previously installed OSs) and then your Linux(es). . . In addition to that, your BIOS must be capable of booting from USB. Poke around in your BIOS setup and look for something like "boot devices" where you can set it to boot from USB.
Ok, 10g for m$ xp, another 10 for each linux, and whatever is left divided into M$ programs and documents
Also, if you're going for a lot of installs, make sure to plan your extended partitions ahead of time! I've run into some probelms where I ran out of possible partitions, and had to wipe 1. (Then I created an ext. and copied others in)

and can I just use the partioning tool in windows xp?
. What I would do is: . Use XP to make four partitions; one for WinXP (~20-30GB), one for Linux#1 (~20-30GB), one for Linux#2 (~20-30GB), and the remainder of the disk for data. Install XP and format the data partition as NTFS. Install Linuxes. Linux should be able to repartition Linux#1 and Linux#2 during the install. . I've never actually done this, so verify before proceeding.

... I got enough computers to screw around on .... LOL
. IIRC, Linux installs the GRUB boot-loader, which allows you to choose which OS you boot into.

You need to partition it first. After that it should be easy, just do xp first (it has a habit of erasing other OSes
