Here are steps on how you can install xp on pre installed win 7.
On the Setup of your bios.
Choose the ATA instead of AHCI on the SATA configuration..
then now apply the changes. then insert your cd on the cd rom. make sure you have chosen the cd as your first boot device.

What you have to do is power on the Laptop and then press F2 to get into the BIOS menu. Then scroll down to the SATA option and change it from ACHI to Compatibility then exit saving your changes (F10) and then reboot your Laptop from the XP Operating System disk.

It will now let you install Windows XP or any other Operating System.

I too have been searching for answers on various sites and forums and none of the suggestions (including downloading XP drivers) worked.

This definitely works (at least for the Toshiba L300 Laptop anway).

Good luck
Thanks so much!
