Ruined grub on Samsung NP300U1A, is it possible to brick using UEFI on a live usb?

http://ubuntuforums.org – First of all, I am not using Wubi and I obviously have installed Ubuntu on my system before. For those who may not know, there has been a problem with some Samsung laptop models hardbricking, resulting in an unusable motherboard after an attempt to install a new OS or run a live cd/usb through the BIOS using UEFI. My model is from July 2011, and runs (or did) Windows 7, not Windows 8. I did find one person who claimed to have had it happen to his new laptop which did run Windows 7, however. So essentially, I am asking, can this still happen to my system even though I've already installed Ubunt (Hardware)
