Got it. mSATA drive is perfectly fine, huh...

UEFI: 1.18 with added support for increased number of /multiple devices, see

Maybe not to the latest 1.46 but at least either 1.18 OR 1.19 may resolve your problem, and since we know the mSata itself is functional this may as well be a compatibility issue (hence we could not figure out your Msata brand in the first place, other than known brands) (I have seen this mentioned in lenovo support also,)
