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.
