Andrew, as per http://us.acer.com/ac/en/US/content/drivers an update is
available for your BIOS (2.17). If you update to this following

I've confirmed that the 64-bit saucy daily build from 2013-09-20 fails
to boot with this message:

[Ok]
Retrying with secure boot disabled allows it to boot without error.

Given the number of bugs that the Kernel Team receives during any
development cycle it is impossible for us to review them all. Therefore,
we occasionally resort to using automated bots to request further
testing. This is such a request.

I have an Asus 1015e but my UEFI settings look slightly different than
that and I still can't get it to boot a live USB stick using the 9-2
daily image. It still hangs at a blank screen even with secure boot
disabled as described in #1200986

I just tested a recent nightly build from
http://cdimage.ubuntu.com/daily-live/current/ on a Asus EeePC 1015e with
Windows 8 pre-installed.
I had to disable Secure Boot from UEFI (as shows here

There have been some recent secure boot changes. Can you test today's
image and post back if this bug is fixed or not?

Hi, I have the same problem with my Asus R500V (K55VD).
The 20130305 daily live for raring doesn’t boot either.
There was no need to swich to legacy bios for me, just switching secure
boot on and off makes the live fail or boot.

For the sake of completeness I've tested the last upstream kernel (currently

The secure boot blocks with the Invalid signature detected message while
loading grub AFAICT, so before loading any particular kernel.
With secure boot disabled both the

Thank you for taking the time to report this bug and helping to make
Ubuntu better. It seems that your bug report is not filed about a
specific source package though, rather it is just filed against Ubuntu
in general. It is important that bug reports be filed about source
packages so that people
If you encounter the bug when booting the Live CD (or alternative
installer), file the bug against the kernel.

Would it be possible for you to test the latest upstream kernel? Refer
to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest
v3.8 kernel[0] (Not a kernel in the daily directory) and install both
the linux-image and linux-image-extra .deb packages.
If this bug is fixed in the
I'm not quite sure how to test that. Should I modify the Ubuntu 12.10
installation media to use the v3.8 kernel? If so, do I need to do
anything special to generate /casper/vmlinuz.efi.signed?
