Installing Windows XP on a Pre-installed Windows Vista Computer

A friend approached me with an HP 530 laptop which had Windows Vista pre-installed on it. Because currently there are so many softwares out there that are not compatible with Vista, he wanted to switch to Windows XP. Unfortunately, the Windows XP setup could not see the hard disk. This was the error that was cropping up: "No Disks found on the computer..."

This friend told me that he had to tried to get through the problem for over a week and it was giving him sleepless nights. We tried to google together and the very first result page returned, had the solution! The solution was simple: Simply turning off support for SATA drives in the BIOS settings played the trick.
