For the first time I'm attempting to dual boot Windows 7 and XP. Following the instructions on TechSpot I was able to create a partition without any problems. However when attempting to install XP it tells me that it can't find any drivers and when I press anything blue screen shows up saying the problem seems to be caused by the following file: setupdd.sys
I guess you are trying to install XP on a SATA drive. That requires you to have the sata drivers on a floppy disk or slipstreamed onto the XP disk, in addition the XP disk needs to contain at least SP1 to install on a sata drive.
