Win 7 install stops /nothing boots

I have two drives, !st with XP PRO SP3 installed. I'm going to do a clean install on it.
A second drive with a partition for Win 7-7048. I've attempted two installs [dual boot, once with XP and one with Vista.
Each install has stopped at the same spot. When Win 7 is finished copying files and does it's 1st boot, at the point it gets to boot from CD.....It stops, just a cursor. It will let you boot a CD but it will go no further. I can't access either drive.
I.I've tried a lot of things to get either to load. Install repair on Win 7. MBR repairs, boot loaders, every utility known to man that doesn't wipe out XP-I'm stubborn.
I'm going to wipe out xp on this rig, but I want to know what I'm doing wrong.

I don't recall that option and you can bet I will look for it the next time I go in. I need this rig up until I get a laptop repaired! :) I don't think I could work on a computer w/o access to the web!

Cellphone? What's that?
Don't know-don't care-won't have one! What ever it is.

I've seen somewhere, that if your BIOS has an AHCI/RAID feature for IDE/SATA drivers, you must set it to AHCI or Windows 7 will give you this error at first boot...Not sure if it applies here but you could give it a try.

I had to go take a look and in bios, sata is either enable/disable so is raid. Maybe there is a choice during install but I don't recall it.
