totally had a similar problem once. try this.
boot into bios, go to the last screen and select "set user default".
hit save, reboot
enter into the bios again, do the same thing, go to the last page, select "set user default", save reboot.
on my G51 i had the same problem when trying to install a second hard drive. it would show up in bios, then not be present in the OS, go back to the bios and it'd be gone. heard it was just a bug in the bios. hope this helps.
do not set it to ide mode, leave it in ahci.
