Whether or not you want it to install over Windows XP, is up to you.
Xandros defaults are as follows.
1. Detect existing Windows installation.
2. If Windows installation exists, then resize the Windows partition (C:\). To allow room for Xandros.
3. Install Xandros along-side of Windows
4. Install a boot loader to the disk, so you do not need a disk to boot to Xandros.
As for the installation problem. There could be a few different issues. Assuming that it just loads the installation screen, then jumps to the "Press Enter to Reboot" screen.
If you have any USB devices, such as cameras, scanners, or printers, etc... You may want to unplug them, before trying to install Xandros.
Xandros does not fully support all DMA controllers, or Power Management interfaces. So either of those could be causing a problem. You may need to press the "Space bar" when you boot from the CD, and try a couple of the troubleshooting options.
There is also some command, "ide=nodma" or similar, which could be used, if the Troubleshooting options do not work.
Also, Xandros has a very good support forum, located at 'http://forums.xandros.com'
