Gigabyte GA-H110M-S2H with Toshiba 500gb HDD and Samsung 860 Evo 500gb SSD, BIOS version F25.
Did a fresh install of Windows 10 Home on the SSD because I couldn't clone it from the HDD (different sector sizes). Used MS Media Creation Tool to do that. With both drives connected and BIOS settings of "Other OS" in Windows 8/10 Features and Legacy enabled in Storage Boot Options Control, the thing goes ok to a screen asking me which Windows installation to boot from and then continues to boot correctly according to which ever of the two drives I select. I've done that multiple times as I installed programs on the SSD, installed the 1809 update + copied data over etc from the HDD.
But if I remove the HDD, the system complains that there is no bootable device. I've searched all over and am getting nowhere resolving this, even after changing some of the BIOS settings so that it doesn't use "Other OS". Any ideas? The SSD is definitely still connected.
