Testing the 14.04 daily server images, I noticed a minor error popping up at boot time. See attached photo.

I call this 'minor' because the system will still boot by itself within 10 seconds or so of the error popping up.

This only seems to happen so far with Advanced Format disks when installed in EFI mode. I tried two different hard drives and got the same result.

Systems that are not equipped with Advanced Format disks but installed in EFI mode do not show this error.

Steps to reproduce:

1) Install 14.04 amd64 daily server build.
2) System needs to have an Advanced Format disk installed and needs to be booted in EFI mode.

Actual Results:
Installation finshes fine but upon reboot the "failure writing to sector" error pops up after the grub menu. System will boot on its own after about 10 seconds.

Expected Results:
Boot without the error message

The disk layout on this drive according to Parted:

Model: SEAGATE ST91000640SS (scsi)
Disk /dev/sda: 1000GB
Partition Table: gpt
