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

[Colin Watson]

Yeesh.  I hate UEFI - this should clearly be impossible with correctly-
written firmware.

How did you go about creating the live USB image?  The 12.04.x images
don't have the right bits to make this work by just dding the image to a
USB stick, but the usual failure mode is simply that the image is only
bootable in legacy mode, not that it is available for UEFI booting but
bricks the machine.  Did you dd or otherwise raw-write the image to a
USB stick, or did you use some program I don't know about to convert it?

If somebody has an unbricked but otherwise appropriate laptop and is
willing to risk it, it would be worth trying out a recent 12.10 daily,
because this is built in a somewhat different way which should allow for
proper hybrid UEFI CD/USB booting.  If this works, we could backport
that to 12.04 without too much trouble.

Title:
  UEFI boot live-usb bricks SAMSUNG 530U3C laptop

Status in Ubuntu CD image build software:
  Confirmed

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.
