I have a Sabertooth 990FX/Gen3 R2.0. On initial boot, can I use the boot menu function to select to boot from a WD Raptor or from a Samsung 840 Pro series SSD? I have Windows 7 Pro x64 on the 300 Gig Raptor, and Windows 8.1 Pro x64 on the 128Gig Samsung 840 Pro series ssd. Any ideas or suggestions???
