I am experiencing the same issue as @Damian_Edwards when trying to use a Samsung 990Pro’s OPAL2 hardware encryption. In my case the system is a FW13 13th Gen Intel CPU.
Following the guides completely, I got Windows 11 installed where it enabled hardware encrypted bitlocker. Upon next boot I am receiving the same Boot Manager message where the UEFI cannot see the drive to boot from. Doesn’t matter whether I have Secure Boot enable and enforced, optional or disabled, the very same issue occurs. I went a step further and tried to use DISKPART and BCDEDIT to repair the boot partition, to no success.
I have another system with an Asus motherboard and this system allowed me to use hardware encryption with my 990Pro and W11Pro 23H2. Something is wrong with the FW13 UEFI/BIOS. Can we get this fixed please? @Twistgibber @nrp @Kieran_Levin @ctl
