unsigned images installed
I've installed Ubuntu 12.04.2 on a Medion Akoya laptop with Windows 8 preinstalled. Afterwards, Windows wouldn't boot, so I've run boot-repair from ppa:yannubuntu/
On the other hand, I could only get Ubuntu to run by selecting an older version of the kernel (3.5.0-17) manually in grub under "Advanced Options" (It took me a few days to find this out). The reason is that boot-repair left two newer unsigned kernel versions behind (3.5.0-23 and 3.5.0-25). I have now installed the corresponding EFI signature packages manually, but maybe a future version of boot repair could do this automatically.
Also, I wonder if future automated updates will load the signature packages correctly.

Hi Sebastian, thanks for your feedback.
Boot-Repair should handle correctly EFI signatures, so you should transform this question into a bug report.
According to the log, Boot-Repair should have installed a signed version of the newest kernel (3.5.0-25), and left the other kernels unsigned (3.5.0-17 and 3.5.0-23).
How did you check that 3.5.0-25 was unsigned ?
Which signature packages did you install manually ?
Dear YannUbuntu,
thanks for the quick response. I thought about a bug report, but maybe it is a "linux-
Here are the commands that boot-repair asked me to type in (copied from .bash_history)
sudo dpkg --configure -a
sudo apt-get install -fy
sudo apt-get purge -y --force-yes grub*-common shim-signed linux-signed*
sudo apt-get install -y --force-yes grub-efi-
The purge command told me that one could remove the 3.5.0-23 version, but it seems to have stayed installed.
The install command then loaded a bunch of 3.5.0-17 packages (if apt keeps a log and you tell me where it is, I will mail it to you). I noticed that because of the lower version number.
When booting the standard option (3.5.0-25), the screen simply stayed pink. After I found out that I could boot the 3.5.0-17 kernel, I installed "synaptics" and had a look at the installed packages. The 3.5.0-17 version had two extra package named "linux-
Another point: linux-signed-
If you still think that I should file a bug report, I will do that. But for boot-repair, or for some of the kernel
packages?
Best wishes, Sebastian

strange, I can't find linux-signed-
How many weeks ago did you use Boot-Repair ?
Dear YannUbuntu,
according to the log file, it was last tuesday, and I donwloaded it from
your ppa immediately before use.
When I tried to install the most recent signed image, I also noticed that
in synaptic, the package "linux-
However, it was definitely downloaded by bott-repair.
I am including the relevant parts of /var/log/

If there are other logs that you would like to see, please tell me
quickly, because my son will take the computer starting from monday
morning.
Best wishes,

PS: I could file a bug report, but at which place? It is not clear to me
that this is a bug in boot-repair.

Dear YannUbuntu,

Anyway, thanks for your help,
