also check if the sata controler is set for ide or achi mode. if it set to ide you need to switch it to the other mode for an ssd to be seen.
Thank you for replying! I don't know how I can set that option. My BIOS has VERY limited options. All I can do is set the date/time, set a password, change the boot order, enable/disable booting from certain types of devices, and set a few other miscellaneous options.
