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.
