I found out about this bugreport _after_ installing Ubuntu 12.10 64-bit on my Samsung Ultrabook Series 5 530U3C-A09NL.
I installed Ubuntu via usb (created via unetbootin on another 12.10 machine), with secureboot off but UEFI on (exclusively UEFI). Immediately after installation, I transferred an apt-clone file from my old machine to my Samsung and installed all {packages,sources,debs}. I also updated apt further, and it told me to autoremove packages like grub-efi-amd64-bin, efibootmgr and so on. I am now on kernel 3.5.0-25, and it seems OK. There's also Windows 8 in the grub boot menu, but after reading these reports I am a bit reluctant to boot it. Ubuntu boots fine, though. There's no sign of any samsung-laptop module in /etc/modprobe.d, nor in lsmod. I tried to change UEFI to CMS in bios, but that leaves me basically without any bootable OS. My question is, why is my machine not bricked? It is bound to happen after some powercycles, should I reinstall everything to be sure or is this issue fixed? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1040557 Title: UEFI boot live-usb bricks SAMSUNG 530U3C,np700z5c laptop To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-cdimage/+bug/1040557/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
