I'm trying to boot from a new ssd. My laptop is an acer aspire with a 5200u and a 940m. I bought an 850 evo ssd and a 9.5mm to 2.5" adapter to add it to my machine. After installing the drive, it is recognized by windows. I used cloning software to clone my existing drive to the ssd, however when I try to change boot order within the uefi bios the ssd does not appear. When messing around and trying to force a boot from a CD-ROM option (through windows advanced startup), it threw a message saying that it was unable to boot from that, however I was given two identical boot drive options (same drive names). I chose the second one and booted into windows to discover that I was on the ssd. All reboots afterwards resulted in booting off of the hard drive, even if I put it last in boot priority.
