When trying to boot into my Samsung 840 Evo 250Gb SSD, I get the message "Reboot and select proper boot device or insert boot media in selected boot device and press a key", the BIOS does however recognise the SSD, it is listed under Legacy Boot, and it is placed first in the boot order.
I have updated the BIOS to the latest version, and I have tried disabling UEFI Boot, but neither made a difference. Windows 10 is already installed on the SSD, I connected it to my PC to install W10 and prepare it for being a HTPC. I figured I could simply put the prepared SSD into the NUC and be ready to go. Could this have caused a problem? Any help is appreciated.
