I have a Dell 14z (Inspiron 5323), and it has a mSATA slot under a bottom cover. I installed a Crucial 64 GB mSATA in it, and it shows up in BIOS and Windows 8 as another drive (the "D" drive). However, in the BIOS, it does not show up as a selection when choosing a boot drive. I've already cloned by "C" drive to the mSATA drive using Acronis True Image, but I cannot figure out how to tell BIOS to boot from it. I realize it was meant as a caching drive, but I thought I could use it as a boot drive. Am I out of luck? Any guidance would be greatly appreciated.
