Comment 12 for bug 1363719

This is a really serious issue for anybody running/upgrading/installing Utopic under UEFI.

Another way of working around this limitation is to install the package from Vivid.

Boot the system from a live CD and use wget to get ahold of the packages from Vivid:

# Needed for the newer version to work correctly
wget http://mirrors.kernel.org/ubuntu/pool/main/e/efivar/libefivar0_0.15-2_amd64.deb

wget http://mirrors.kernel.org/ubuntu/pool/main/e/efibootmgr/efibootmgr_0.11.0-1_amd64.deb

dpkg -i libefivar0_0.15-2_amd64.deb efibootmgr_0.11.0-1_amd64.deb

Then run 'grub-update' (to make sure we have all the kernels accounted for) and then 'grub-install /dev/sdX' (replace X with the number of the harddrive you're using).

After that booting in UEFI mode should be working again.

PLEASE FIX THIS ASAP!
