Hello,

I'm having some trouble UEFI booting with my mobo. In boot menu and in UEFI boot option priorities, only usb-sticks list UEFI as a boot option. UEFI booting from usb-stick works very well. But from SSD-disk not so much. It only lists AHCI as option (should it list/say UEFI?) and booting that wont work.

If I disable CSM it only boots/lists UEFI usb-sticks, not the hard drives.

Hard drive mode is set to AHCI. Aggressive link power management, dynamic storage accelerator and S.M.A.R.T. is disabled. Hot Plug disabled, SATA Device type is set to Solid State Drive.

I have read many documents of how to partition for UEFI boot and what filesystem to use. And tried different things.

I have exactly same (gpt, tried dos/mbr also) partitioning on stick and 2,5" ssd. Partitions have same filesystems (fat16, tried fat32 also) with exactly same contents.

It works from stick but not from SSD.

As a last resort i tried just dd'ing stick contents to ssd, to no avail.

My UEFI version is P2.10 and SSD is Kingston SH103S3120G
