Nice that they are supporting Linux.  A few suggestions in order of

1.  Sell them on a cross-platform development environment (Focus of
current Linux Journal - VMware (http:// under Linux, or better yet separate dedicated systems
for testing.  Don't install Windows XP dual-boot.  Dual-boot with M$ is
a seldom-necessary evil to be avoided if possible, except for situations
like accommodating the kid's games on a home system.  Hardware is cheap
compared to the administrative problems accompanying dual-boot.

2. Make advance preparations for XP clobbering the MBR by using
"mkbootdisk --iso --device boot.iso `uname -r`" to make a bootable CD
image that can then be burned to CD-ROM, boot to FC2, and run "grub-
install /dev/hda".

3.  Make advance preparations for XP clobbering the MBR by creating a
grub boot floppy :  "grub-install /dev/fd0", or use attached script to
make a GRUB boot floppy with a menu, boot to FC2, and run "grub-
install /dev/hda". 

4.  Boot FC2 CD in rescue mode, mount the installation under "/mnt/
sysimage", IIRC, following directions, and run "grub-install /dev/hda"
("\" is M$ notation for directory separators) after Bill Gates clobbers
your MBR.  Beats me why you say it is not there.
