After I updated BIOS/UEFI version to 1101 on an Asus P8Z68-V PRO motherboard Ubuntu (11.10) did not boot. After POST all I saw was a black screen with a blinking cursor in the top left corner.

I booted an Ubuntu 11.10 live-CD and set the flag for the 20 MB partition before my boot partition to "bios_grub". Then I was able to boot and login. But now every time I boot and Ubuntu loads I get the following message:

Disk drive for /boot/efi is not ready or not present.
Continue waiting or press s to skip or m for manual recovery.

I am able to login if I choose to ignore it by pressing s, but what does this message mean?
How can I fix what the message warns about?

After logging in I have noticed that /boot/efi is empty.

The following forum post speaks of the same issue ubuntuforums.org/showthread.php?t=1893030.

Updating to the latest BIOS/UEFI - version 3203, did not have any effect on this issue.

as seen on Ask Ubuntu - Search for 'Ask Ubuntu'
I just updated from 11.10 to 12.04, with no major problems (it took a while to get past a request to restart ssh, mysql and some other services, but I did no fiddling by myself, everything was done by the installer). However, after restarting, grub can't do anything. Picking the new linux installation… >>> More
