Disc Read Error Occurred?

Hello,

I have seen multiple questions on this site for this problem but none that apply to my particular situation.

I have a two year old HP desktop that came with Windows 7 installed on it. I recently purchased a DELL OEM version of Windows XP with service pack 2 to install on the HP computer. To make sure it worked, I first installed it on my old Toshiba laptop from 2006. It came with XP on it but I had recently upgraded it to Windows 7. The installation of Windows XP on the Toshiba laptop went smoothly. When I went to install Win 7 on the HP desktop, it copied the files and my computer went to go reboot to continue the setup. When the computer restarted, a black screen came up with "press any key to begin setup boot..." or something like that (as if to start the installation process?) but then 3 seconds later a message right under it that read "disc read error, press crtl, atl, delete to restart"

No matter how many times I try to go through the setup, it keeps repeating this. At first I didn't delete the partition to reformat it but after I did that, still no resolution. I can't understand what the issue it. I see people talking about changing BIOS but I can't figure out what people are talking about by changing the settings. Why did the installation go so smooth on a really old computer?

I would really appreciate someone's help with this. I can't imagine I need to purchase anything additional to make this work. There has to be some setting I need to change or some step I am missing. Please advise.

Thank you,
