No main boot device recognised, but can boot with an Unbuntu USB, but not Windows. argh.

Fellow Acerians.

I have a Acer Spin 15, v1.1 BIOS.

A few days ago it it didn't recognise any boot device - normally Windows 10 on an M.2 SSD

I swapped the disk but same message - Blue dialog with "Default Boot device Missing or Not failed, insert recovery media, then drive boot Manager.

I tried switching between secure boot, resetting to factory bios settings, removing  motherboard battery - all no difference

They peculiar thing is this...
An Ubuntu 18 USB boot is recognised (FAT32) - I can boot live and install Ubuntu to M2 SSD but on reboot I get the same as above.

A Windows USB boot disk (NTFS) is not recognised.

It's like BIOS is no longer recognising anything except FAT disks.
Has anyone encountered this? I'd like to try a bios update, but I read that it needs Windows.

Any suggestions are much appreciated, I'm stumped.

Thanks
