Welcome to LQ then.
I guess you want to setup a dual boot.
Have you got spare space not formated? or are you going to need to resize
partitions. From what you say I understand you have spare space already.
there is plenty of dual boot tutorial out there. Here is one
Personally, depending on your expertis, and how critical your XP data,
I advise you to 1) consider ad-hoc backups 2) consider adding a 2d HD.
It is much easier / less risky to add another OS to 2d HD.
But this really depends on your expertise.
I do not recommend slack 10 for 3 reasons
- maybe not the best choice for a newbie
- you mainboard look pretty recent, so there might be a sata support problem
- 10.1 and 10.2 are out there
Have you got a sata HD?
You may need to tweak BIOS sata options to have the HD recognised.
If I were you I would first try
Suse 9.3 or 10.0, Mandriva 2005 or 2006 LE, Kubuntu, PClinuxOS...
(look at distrowatch for some ideas and many threads in LQ)
Consider also Knoppix to do the resize or create the partitions in the
spare space. fdisk etc , good idea. You also have GUI (see the ntfs resize link)
and get a feel of Linux,
then just plounge and install whatever distros.
Be sure to make a /home partition
Leave a spare partition (~6 gb) so you can install other distros for trial
Let us know how it goes
