[ale] grub rescue

[Michael Trausch]

I will take a look at this more when I get home... but, do you have the
partition table as it was beforehand? If so, you can use sfdisk to
re-create. Otherwise, we need to look at the EBRs in the extended area.

This is why I hate MBR partition tables, by the way.

You should try running a utility to detect the partition, but don't count
on it working; assume all is lost and hope for the best.  Since it is
encrypted it will be hard if not impossible to detect.
