fixing Acer c710 chromebook that always boots to grub #612

Just wanted to record this somewhere for the Acer C710 owners running MrChromebox 8/7/2018 and i refuse to use reddit

At various times apt-get upgrades under GalliumOS will bork the boot process and leave you at the grub prompt on boot. Thereotically this has been fixed, in reality it has happened to me several times over the years, even a brand new install of galliumos-3.1-sandyivy.iso from USB with all default settings did not help

There are dozens of complicated fixes on the web for this, but for Acer C710 running MrChromebox firmware the solution is rather simple, and basically still a modified version of what's listed on https://mrchromebox.tech/#faq

First test Boot from File, as follows: power-on the machine, hit 'f1' on startup, go to boot maintenance, boot from file, second partition option, /boot/grub/x86_64-efi/grub.efi

If that boots then the permanent solution is simple. The system is just looking in the wrong place for the EFI file. Fix that as follows

sudo su 
mkdir -p /boot/efi/EFI/BOOT
cp /boot/grub/x86_64-efi/grub.efi /boot/efi/EFI/BOOT/BOOTX64.efi

thanks
