I'm trying to go from Windows Vista to XP on a Toshiba Satellite A205-S5804. When I try to install Windows XP on the Toshiba Satellite A205-S5804, I get the message "There is no hard drive available". I tried to go in CMOS to change from SATA to IDE, but there was no option to do that on this particular model. Has anyone had this problem? If so, please shed some light on what to do. Thanks a million in advance.
