I just learned today while installing Windows XP SP2 in Compaq/HP laptop that when trying to install a fresh copy of Windows XP to this machine, it will cause you an error like this:
Unknown Device:
There is no disk in this drive …
This is because SATA drivers for this laptop are not yet loaded upon installation. To fix this, just go to your BIOS setup\System Configuration\SATA Native Support. Change the status from ENABLED to DISABLED.
From here, try loading the bootable Windows XP SP2 and it will work just fine.
