I installed GalliumOs on my C720P dual boot (chrx) and I am very satisfied.
But I have a problem.
After the last update, I turned off my computer.
Now when I want to access GalliumOs with CTRL + L, the hard disk boot does not work.
I tried the procedure described here but it does not work. Https://www.reddit.com/r/GalliumOS/comments/5mhjd3/acer_14_wont_boot_after_grub_update/
mount $GALLIUMOS_ROOT /tmp/a
mount -o bind /proc /tmp/a/proc
mount -o bind /dev /tmp/a/dev
mount -o bind /dev/pts /tmp/a/dev/pts
mount -o bind /sys /tmp/a/sys
mount -o bind /run /tmp/a/run
chroot /tmp/a /bin/bash
An idea ? Thank you for your help.
