I am dual booting Ubuntu 16.04 and Windows 10 but am having a sporadic issue.

GRUB will show up, and if I boot into Ubuntu, it works fine. If I shut down from Ubuntu and restart, everything works great.

However, after I boot into Windows 10, shut down, and reboot, the GRUB menu does NOT appear. Instead I am greeted with the Minimal BASH-like line editing is supported message:

Minimal BASH-like line editing is supported. For the first word, TAB
lists possible command completions. Anywhere else TAB lists the possible
completions of a device/filename.

The only way for me to temporarily fix this issue is if I boot Ubuntu from my USB stick and run the boot repair. It claims it has fixed the boot menu/GRUB, but the process above continuously repeats. Booting into either OS works, but specifically after shutting down from Windows 10, the Minimal Bash message appears.

I tried this command from Windows 10 but it does not appear to have changed anything:

bcdedit /set {bootmgr} path \EFI\ubuntu\grubx64.efi

I am booting in UEFI mode with SecureBoot mode disabled and have an Acer Aspire V7-582P-6673 if that helps.

  • Have you set "trust" in UEFI for /efi/ubuntu .efi boot files? All Acers seem to need that. Acer Aspire E15 will not dual boot, many details Trust settings in step 35 askubuntu.com/questions/627416/… Some older threads mention downgrading UEFI, others says newest from Acer works. So make sure you have newest UEFI from Acer.

Try with the live session, on the USB or cd, to reinstall grub-efi. Open a terminal and enter the following commands:

sudo mount /dev/sda# /mnt

Replace the hashtag in /dev/sda# with the number representing the partition where you had Ubuntu 16.04 installed. You can use gparted to do it.
sudo mount /dev/sda# /mnt/boot/efi

Replace the hashtag in /dev/sda# with the number representing the efi partition. It's usually /dev/sda2.
sudo mount -o bind /dev /mnt/dev

sudo mount -o bind /proc /mnt/proc

sudo mount -o bind /sys /mnt/sys

sudo mount -o bind /run /mnt/run

sudo chroot /mnt/

sudo apt-get install --reinstall grub-efi

sudo update-grub

reboot, to realize if it works.
