So you should be able to do sudo mount /dev/sda2 /boot/efi to mount it (or /dev/sdb2, depending). Then once you have replaced that grubx64.efi with the one that allows booting unsigned kernels, you should run 'sudo umount /boot/efi' to make sure the disk is cleanly unmounted. After this, you should have a secureboot-enabled grub on the internal disk which allows you to boot to a different unsigned kernel on the flash drive in order to reset the firmware state. > Thanks again for any help! I'd really love to sort this out :) Sorry this is such a mess. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1734147 Title: corrupted BIOS due to Intel SPI bug in kernel To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/1734147/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
