This may be the bug that is affecting me. I have a Lenovo Carbon 2. During about half the kernel updates in Utopic, the computer subsequently refused to boot. AT ALL. I had the bios setting set to dual, with UEFI first and legacy second. But changing bios setting to "legacy" did not work. My only solution was to re-install with a different kernel. (I went back to Trusty, which worked.) I have another Lenovo computer that did not have this problem at all, runs Utopic like a champ, with every update. I have been unable to file a bug report because I seem to have no useful information.
I am worried because today, 10/29 Trusty installed kernel 39 during my morning updates. So I ran update-grub immediately to ascertain which kernel I was currently running, and which I would next boot into. My currently working kernel is 37. (You will note that I have lowlatency installed too. I have tested. There is no difference in boot behavior between low-latency and generic. ) Found linux image: /boot/vmlinuz-3.13.0-39-lowlatency Found initrd image: /boot/initrd.img-3.13.0-39-lowlatency Found linux image: /boot/vmlinuz-3.13.0-39-generic Found initrd image: /boot/initrd.img-3.13.0-39-generic Found linux image: /boot/vmlinuz-3.13.0-37-lowlatency Found initrd image: /boot/initrd.img-3.13.0-37-lowlatency Found linux image: /boot/vmlinuz-3.13.0-37-generic Found initrd image: /boot/initrd.img-3.13.0-37-generic Adding boot menu entry for EFI firmware configuration done If I shut my computer down and then re-boot and I cannot boot, which is what I expect will happen, I will update this comment. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1366546 Title: Ubuntu doesn't provide \EFI\BOOT\BOOTX64.EFI for UEFI systems To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/1366546/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
