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.

The F12 menu is a BIOS-level menu that allows you to select the boot DEVICE => NOT a specific partition on that device.

Most likely you need to change the active partition on your system to the partition where you've installed Grub.

Boot to a utility that lets you view and modify the MBR on your disk, and see which partition is currently active.    Note that if you change the active partition incorrectly, the system won't boot ... so be sure to pay attention to which one is CURRENTLY active so you can change it back if you make a mistake.

If you don't have a good disk utility that you can do that with, use Boot-It BM.    Just create a bootable CD; boot to it; click CANCEL at the first prompt (don't install it on the disk); then OK to go to Maintenance mode.    Then click on Partition Work, and you can then click on "View MBR" to see the MBR and change the active partition.

Incidentally, Boot-It is an EXCELLENT boot manager and partition manager => you may want to consider buying it and using it to manage your multi-boot setup.

Hi,

I will try to answer your question if i am correct in understanding the issue you are facing.

The best option to make your system Dual-Bootable like yours is to install Ubuntu first and assign some free space ( Not Formatted ) for your windows OS.

Once you are done with Ubuntu installation, boot the system with windows media and windows will be able to discover free space for the installation. (Windows does not recognize any ext3 / ext4 file system partitions). Once you are done with both the installations you should be able to choose the OSes while booting.

You can also use any third party boot managers as suggested by garycase.

Hope this helps.

Best Regards
Raghav.

Thank you, Experts.

"...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: 0000,0001,0002,2001,2002,2003
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
BootOrder: 0001,0002,2001,2002,2003
Boot0000* ubuntu      HD(1,GPT,1ff15ea8-2515-4c5c-a793-921644dc83cb,0x800,0x32000)/File(\EFI\ubuntu\shimx64.efi)
Boot0001* Windows Boot Manager      HD(1,GPT,1ff15ea8-2515-4c5c-a793-921644dc83cb,0x800,0x32000)/File(\EFI\Microsoft\Boot\bootmgfw.efi)RC
Boot0002* Linpus lite      HD(1,MBR,0x4294967271,0x2caa70,0x1280)/File(\EFI\Boot\grubx64.efi)RC
Boot0003* Unknown Device:       HD(1,GPT,1ff15ea8-2515-4c5c-a793-921644dc83cb,0x800,0x32000)/File(\EFI\ubuntu\shimx64.efi)RC
Boot0004* Unknown Device:       HD(1,GPT,1ff15ea8-2515-4c5c-a793-921644dc83cb,0x800,0x32000)/File(\EFI\ubuntu\shimx64.efi)RC

Boot0007* Unknown Device:       HD(1,GPT,1ff15ea8-2515-4c5c-a793-921644dc83cb,0x800,0x32000)/File(\EFI\ubuntu\shimx64.efi)RC
Boot2001* EFI USB Device      RC
Boot2002* EFI DVD/CDROM      RC
Boot2003* EFI Network      RC
ubuntu@ubuntu:~$

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.

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