currently I'm downloading ubuntu 12.04.2 from official

http://www.ubuntu.com/download

I just read on m.h-online.com and on linux.com that Secure UEFI Boot version have been released.

So I wanted to know if I'm downloading that secure Boot UEFI version from (http://ubuntu.com/download) or I have to download that Secure boot UEFI edition from somewhere else?

Since I have a Samsung laptop and I don't want to take the risk of bricking it.

Listen recently some samsung laptops were bricked permanently while booting linux to them as i googled more i found that Ubuntu 12.04.2 has that UEFI fix present in it. Currntly Ubuntu 12.04.2 is on my downloading list which i downloaded from (ubuntu.com/download) so my question is where is that UEFI FIXED version of ubuntu 12.04.2? Is it seperate version (download) or is it already there in ubuntu.com/download which im downloading now? –  ANiK3T Mar 19 '13 at 14:10
    
If your Samsung Laptop has UEFI don't install any OS. Its a firmware bug which Samsung are aware of. This is not just a Linux issue Windows can Brick the Computer too. It's not an issue with older non UEFI laptops. If yours is UEFI I would return it to the supplier for a refund. I'm sure Samsung will fix this but its not fixed today and you risk bricking the machine. –  Warren Hill Mar 19 '13 at 16:50

My advice is to not run ANY OS in EFI mode on recent Samsung computers. As described by Matthew Garrett, this firmware can be bricked even from Windows. The initial Linux kernel fix just fixed the most common path to the underlying bug, but the bug remained. I've heard a vague report that there may be a second workaround in even more recent kernels, but I don't have details and I don't know if this really completely eliminates the risk.

Given all this, my advice is to do one of three things:

  • Return the computer to the store for a refund and buy something that's not defective.
  • Wipe the hard disk clean and re-install everything you want to use in BIOS mode rather than in EFI mode.
  • Put the computer back in its box until Samsung releases a fixed firmware.
