[Bug 1040557] Re: UEFI boot live-usb bricks SAMSUNG 530U3C, np700z5c laptop

Steve:

I did not expect this to happen in my wildest imagination and, hence,
did not pay too much attention to the exact steps I followed. But I will
try to answer your questions the best I can:

> Can you confirm that you had specifically configured your BIOS to boot
in UEFI mode?

Yes. I tried booting the computer using the 12.10 (64-bit) USB stick but
it would not recognize it as a bootable device. I tried changing several
obvious things in the BIOS such as the boot device order. But these
changes did not work. Eventually, I found an option that said something
to the effect that enabling it will allow both legacy and UEFI boot. I
remember that it was on an unexpected place in the BIOS (AFAIK). This
allowed me to boot from the USB stick.

> Can you tell us how you prepared the USB stick for booting?

I used Startup Disk Creator from another machine that was running Ubuntu
12.04.1 (64-bit).

> When you tried to boot the image, what happened? At what point did the
machine become unresponsive?

The machine booted up from the USB stick. During the initial stages of
the boot process the screen blinked and I saw a UEFI-related message on
the top-left corner of the screen. The message was only displayed for a
fraction of second so the only words that I remember were "UEFI" and
"secure". Also, the message consisted of only about four of five words.

After this I saw the familiar Ubuntu bootup screen with the image of a
keyboard and a person/stick-figure at the bottom of the screen. I
usually press space bar at this stage and select the option for
installing Ubuntu on the system instead of using it as a "live cd". This
is what I ended up doing. I figured that it will do its thing and take
me through the installation process next. At this point I went away to
do something else hoping to return to the installation screen in a
couple of minutes. However, I returned to a black screen containing
several error messages. These were not kernel oops messages as far as I
remember. The messages complained about something going wrong with the
CPU (sorry, I should have written these down but that is all I
remember).

I was using a really really really old 1GB USB stick that I had dug up
from a forgotten corner of a couch. So, I immediately blamed it, ignored
the error messages, recycled power, and started my quest for another USB
stick. After this the computer never booted up. :(

>  I hope you are able to get the machine recovered through the vendor.

Lets hope so.

Bug description:
  I cannot provide detailed log massages because laptop is bricked right
  now.

  If you have courage to try it select UEFI boot from bios and than try
  to boot laptop using liveusb (made form Precise Pangolin 12.04.1
  amd64).

  Laptop hangs up in black screen. If you force power-off, after it,
  laptop wont start. I mean it not event start bios, just black screen
  no sounds nothing.

  I filing this report, because i already bricked second laptop. At
  first i thought it was unrelated issue and laptop was fixed by
  warranty service (replaced motherboard), but after second time i quite
  sure.
