Hello,
I also tried to install HA OS on Fujitsu Esprimo Q920 without luck, there are some problems with UEFI at this devices: Service Facts UEFI-BIOS bug Affected and unaffected products
In order to use Q920, I found a workaround, I used an USB 3.0 adaptor for SSD/HDD 2.5. It works perfect!
After you plug the USB, you need to enter in Boot menu and select USB as first boot device.
