Would anyone like to have a try on below workaround? 1. boot with a live medium (the live mode of the installer is OK) 2. open a terminal or switch to a text console by pressing ctrl-alt-f1 3. execute below commands
cd /tmp mkdir efi target # suppose /dev/sda1 is the EFI partition sudo mount /dev/sda1 efi # suppose /dev/sda2 is the /root partition sudo mount /dev/sda2 target # check if there is efi/EFI/boot/bootx64.efi # if there is no such file, proceed # if there is already such file, then this workaround won't work for you, DO NOT PROCEED find efi/ # here is the workaround, I guess some BIOS requires EFI/boot/bootx64.efi to be found # to recognize the partition as a valid EFI partition, so we put a dummy placeholder there mkdir -p efi/EFI/boot cp efi/EFI/ubuntu/shimx64.efi efi/EFI/boot/bootx64.efi # now we reinstall grub to reinstall the efi boot entry sudo grub-install --efi-directory efi --boot-directory target/boot /dev/sda # now we can reboot to check if it works sudo reboot -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1302939 Title: Installing Ubuntu 14.04 on Lenovo H520 leads to unbootable system To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubiquity/+bug/1302939/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
