When I installed ubuntu 14.04, several months ago, I enabled hard disk
encryption. The computer is an old one, and there were some things I
didn't like about the way the LTS version worked, so I decided to update
The install was stopped by a request to enable Microsoft TTFs. This
window could not be closed, authorized or bypassed, and after several
hours of waiting for something to happen, I switched off the machine.
I downloaded a copy of 14.10 and burned it to a DVD on another computer,
and attempted to install from the DVD.
The BIOS needed changing to permit the boot, but I found that it
could not be changed. The message on the BIOS screen said that drives
noted in brackets could not be made bootable. They were all
bracketed. I assume the HD encryption system has set the BIOS so that
the DH cannot be violated by an unauthorised user.
When I try to restart the faulty machine, I am asked for my Disk
Encryption Password. That part works, however, I then get a small blank
window asking me what I want to do. There is a flashing cursor, but it
goes away with any action of the keyboard or mouse, and the computer
I have backup of my home directory, so I am not stuck, but I am stuck
trying to recover the usefulness of the old computer. Does anyone have
a suggestion, or better still, a solution?
