I am trying to install Ubuntu 17.10 on a Acer desktop with BIOS Version 2.14.1219 (
dmesg | grep Acer reports
Acer Veriton M6620G/Veriton M6620G, BIOS P01-A1L).
As far as I can tell, the Ubuntu installer books via EFI and then assumes EFI for its installation (
fdisk /dev/sda reports
sda1 afterwards). It does not allow me choosing otherwise.
But when I try to boot the installation I get this error:
ERROR: No boot disk has been detected or the disk has failed.
When I enter a shell by selecting
Try Ubuntu without installing after booting the install disk again, I can see that
efibootmgr does not recognize the hard disk that received the installation as a boot entry. When I try to add it with
efibootmgr -c, this setting does not persist and the firmware apparently ignores it.
dmidecode -t0 indicates that the firmware supports both UEFI (
UEFI is supported) and BIOS compatibility mode (
BIOS boot specification is supported). As far as I can tell, it (the BIOS) does not allow me to influence which boot mode it actually chooses.
Overall, the issue seems to consist of Ubuntu installing for EFI but the Acer firmware not being able to boot from this installation. The same happens when I attempt installing Ubuntu 16.04 (instead of 17.10).
So how can I install Ubuntu on this Acer desktop?
