Dual boot of Ubuntu 16 on Acer E-15 E5-575G
Dear Experts.
My laptop is Acer E-15 E5-575G-76YK
After setting up BOOT password, disabling secure BOOT,
installing Ubuntu 64 bit from USB,
the computer still does not show up
GRUB menu, but
only shows up Windows Boot Manager menu if to
click F12 at boot time.
There were no error warnings after Ubuntu installation.
After installation, I rebooted from USB again and ran
boot-repair. Boot-repair reported an error, but not clear which one.
My SSHD is /dev/sda.
Windows is on sda3
Ubuntu on sda5 and 6.
It was a state of hybernate, but I fixed it by "shutdown /s /t 0".
Boot-repair log is attached.
Thank you.

PS. Sorry for the typo. I meant "... install Ubuntu first ..." not "... Windows first ... "

Setting "trusted" entries in boot-firmware-utility is a final step which solves the problem.

"...Most likely you need to change the active partition on your system to the partition where you've installed Grub...." this advice seems irrelevant because all 2 partitions on sda are marked active with asterisk
The main problem is that when setting:
BootOrder: 0000,0001,0002,2001,2002,2
from live CD and after rebooting, something erases an entry "0000" like this:
BootOrder: 0001,0002,2001,2002,2003
See details of "erased" settings:
ubuntu@ubuntu:~$ sudo efibootmgr -v
BootCurrent: 0002
Timeout: 0 seconds

On top of this, efibootmgr does not work properly
ubuntu@ubuntu:~$ sudo efibootmgr -t 10
efibootmgr: Could not set Timeout: Invalid argument
It can be a vendor (Acer) problem or broken version of
ubuntu@ubuntu:~$ sudo efibootmgr --version
version 0.12
I recall that version 0.24 is good.
The advice to install Windows first? ... I am not in position to spend $150 for Windows media ... just to find out that unknown problem is not resolved ....
Thank you.
