My wireless USB keyboard is not recognised by GRUB loader, but I use to wait for 10 seconds and Ubuntu was started since it is default in the boot menu.
This morning, no 10 seconds countdown was performed and I was unable to boot, I just stuck in the GRUB menu.
I took PS2 keyboard, connected it and booted.
Any idea how this happened? Some update?
Now I want to configure GRUB to automatically, with no countdown, boot first menu option.
Part of my current /etc/default/grub:
GRUB_DEFAULT=0 #GRUB_HIDDEN_TIMEOUT=0 GRUB_HIDDEN_TIMEOUT_QUIET=true GRUB_TIMEOUT=10
