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:

  • You should look for an option concerning legacy usb support in your cmos (bios) settings and activate it. I used to have the same problem and took me a while to figure it out. – kicsyromy Aug 31 '11 at 7:59
  • Yes, I google that out, thanks. But I want to configure GRUB to pick and run Ubunutu by default, without me touching the keyboard. – umpirsky Aug 31 '11 at 8:17
  • as it shows in your /etc/default/grub the default is 0 (i.e. the first option which i'm guessing is ubuntu) now all you need to change is the grub timeout value to 0 and run a sudo update-grub – kicsyromy Aug 31 '11 at 8:50
  • But if now GRUB_TIMEOUT=10, that means it should wait for 10 seconds, and boot first option (Ubuntu). But it doen't, it waits forever. Why? – umpirsky Aug 31 '11 at 9:13

    I turned USB keyboard support in my BIOS and now keyboard works in GRUB. – umpirsky Sep 1 '11 at 5:59
