I'm preparing to upgrade my desktop computer (in sig) from Win7 to Win8. When I check BIOS and/or Boot Menu the only drive that shows a UEFI option is my HDD (1GB Western Digital WD10EARS-00M). I can choose it for either UEFI or non-UEFI boot. Neither of the SSDs show a UEFI option. The old Kingston SSD, I'm not surprised, but why doesn't the 120GB Intel 520 SSD -- which is my boot drive -- show a UEFI option? The Intel SSD is plugged into a SATA3 (6Gbps) port and the HDD is plugged inot a SATA2 (3Gbps) port, if that's relevant?
