I have a new and updated Ubuntu 10.10 system. If I purposely force a restart by using the computer's reset button, or hold the power button down to simulate a power outage, when I turn it back on, it will stay on the GRUB2 boot screen and not continue.

Can I force it to resume to the default boot entry without waiting for me to press enter on it?

This is for an unattended home server so if it does restart and I wake it on LAN, I want it to continue booting as normal, not hang at the boot screen.
