After successfully installed Windows 8.1 on a Plextor PX-G256M6e M.2 PCIe SSD, system halt on first reboot saying "Boot Device not Found Error Message".
The bios was updated to v02.13 Rev.A (Feb 2013).
The computer is a EliteDesk 800 G1 Mini - G5R49UT.
No option available in bios to set first boot device to "M.2 PCIe".
Did someone have any clue?
Thank you.
