Recently, I got the Ubuntu 17.10 upgrade from this link through command line. I remember getting a ton of
y/n questions in terminal so after a while I just stopped reading the options so carefully and answered
y to all of them. However, I do remember seeing something to do with
efi and I selected yes anyway. The update works fine!
The troubles begin in trying to change BIOS settings. I can get into the BIOS configuration menu by hitting
F2 continuously at startup. I can still change all of the options. It even asks me if I want to save my changes, to which I select
yes, but at the next reboot, no changes are saved. I can't boot from USB drives either. Furthermore, when trying to go into
system setup from the Ubuntu grub menu, it gives me
Error: unable to set EFI variable 'OsIndications'
I use an Acer Aspire ES1-511 running a Dual boot of Windows 8 and Ubuntu 17.10. Both operating systems still load perfectly, but as stated above, USB devices can't boot after the upgrade took place.
I suspect that either the EFI partition is mounted as read-only, there are insufficient permissions, or the drive is in the wrong location.
This is the only forum I could find this problem on, but there is currently no solution, so still I cannot change BIOS settings. What went wrong during the update that would make BIOS settings unchangeable? Are there any commands I can try before just waiting for the next Ubuntu release? I'm running a Dual boot, so maybe I can do something from Windows 8? Any help is appreciated!
