I have a brand new Dell XPS 8700 with windows 7 pro installed. I am trying to install windows XP pro to be able to dual boot. I have already succesfuly set up new partition and am having trouble with the XP install. After a little while into the installation I get the following message "file acpi.sys is corrupted" and the installation ends and windows 7 reboots. I have done research online and haven't been able to find a specific solution to this error message. I have been given several links to dual booting instructions and none of them include this specific error message. Any help would be greatly appreciated, thanks.
