X86 Hardware issues (Graphics, WiFi, Onboard Sound, external DACs, Disks, BIOS/UEFI Boot problems etc.)

Hello Helpful Forum,

I have some new hardware the Fujitsu Futro S740 Thin Client, its a Intel Celeron J4105 x64 machine.

The issue is the unit only boots pure UEFI and does not support legacy boot. I burn volumio to a USB then boot off that USB on the Futro, it boots and allows me to install to internal drive no problems however when I come to boot from the internal drive the computer doesn’t recognise the drive as a bootable drive.

I can temporarily fix the issue by booting a Linux live usb and using efibootmgr to add BOOTX64.EFI to the EFI boot list. The problem is that doesn’t seem to persist after power loss(Time and date are retained fine by CMOS battery).

Is there some way to modify volumio so it is recognised as a boot device please? Windows and Ubuntu installations are recognised fine as bootable and automatically added to efi boot list.

Thanks in advance,

Alex

Edit: I heard the Futro needs GPT partitions, i tried converting the ssd to GPT but still not recognised. one time I could get grub to be recognised with GPT but it then didn’t boot volumio.
