I have the same problem. Since upgrade from 13.10 to 14.04, I've run Boot Repair which failed. I do recall some issues getting grub working when I originally installed 13.04 but don't have a record of how I got it working. Upgrade from 13.04 to 13.10 went OK.
I've spent the last five hours searching so any suggestions would be greatly appreciated. When I try to dpkg-reconfigure grub-pc, I get: chris:~$ sudo dpkg-reconfigure grub-pc dpkg-query: package 'grub-pc' is not installed and no information is available Use dpkg --info (= dpkg-deb --info) to examine archive files, and dpkg --contents (= dpkg-deb --contents) to list their contents. /usr/sbin/dpkg-reconfigure: grub-pc is not installed. sudo grub-install runs and does not report any errors. I've got no installed_devices listed. chris:~$ sudo debconf-show grub-pc grub-pc/partition_description: grub2/device_map_regenerated: grub-pc/timeout: 10 grub-pc/disk_description: grub-pc/install_devices_failed: false grub-pc/install_devices_empty: false grub-pc/install_devices: grub-pc/postrm_purge_boot_grub: false * grub2/linux_cmdline_default: quiet splash grub-pc/mixed_legacy_and_grub2: true grub-pc/kopt_extracted: false grub-pc/install_devices_failed_upgrade: true grub-pc/hidden_timeout: true grub-pc/chainload_from_menu.lst: true grub2/kfreebsd_cmdline: * grub2/linux_cmdline: grub2/kfreebsd_cmdline_default: quiet splash grub-pc/install_devices_disks_changed: chris:~$ sudo parted -l Model: ATA TOSHIBA MQ01ABD1 (scsi) Disk /dev/sda: 1000GB Sector size (logical/physical): 512B/4096B Partition Table: gpt Number Start End Size File system Name Flags 1 1049kB 420MB 419MB ntfs Basic data partition hidden, diag 2 420MB 735MB 315MB fat32 EFI system partition boot 3 735MB 869MB 134MB Microsoft reserved partition msftres 4 869MB 248GB 247GB ntfs Basic data partition msftdata 7 248GB 458GB 210GB ext4 msftdata 8 458GB 966GB 508GB ntfs msftdata 6 966GB 982GB 16.0GB linux-swap(v1) 5 982GB 1000GB 18.3GB ntfs Basic data partition hidden, diag chris:~$ dpkg-query -l 'grub*' Desired=Unknown/Install/Remove/Purge/Hold | Status=Not/Inst/Conf-files/Unpacked/halF-conf/Half-inst/trig-aWait/Trig-pend |/ Err?=(none)/Reinst-required (Status,Err: uppercase=bad) ||/ Name Version Architecture Description +++-==================-==============-==============-========================================== un grub <none> <none> (no description available) ii grub-common 2.02~beta2-9 amd64 GRand Unified Bootloader (common files) un grub-coreboot <none> <none> (no description available) un grub-doc <none> <none> (no description available) un grub-efi <none> <none> (no description available) ii grub-efi-amd64 2.02~beta2-9 amd64 GRand Unified Bootloader, version 2 (EFI-A ii grub-efi-amd64-bin 2.02~beta2-9 amd64 GRand Unified Bootloader, version 2 (EFI-A ii grub-efi-amd64-sig 1.34+2.02~beta amd64 GRand Unified Bootloader, version 2 (EFI-A un grub-efi-ia32 <none> <none> (no description available) un grub-efi-ia64 <none> <none> (no description available) un grub-emu <none> <none> (no description available) un grub-ieee1275 <none> <none> (no description available) un grub-legacy <none> <none> (no description available) un grub-legacy-doc <none> <none> (no description available) un grub-linuxbios <none> <none> (no description available) un grub-pc <none> <none> (no description available) un grub-xen <none> <none> (no description available) un grub-yeeloong <none> <none> (no description available) un grub2 <none> <none> (no description available) ii grub2-common 2.02~beta2-9 amd64 GRand Unified Bootloader (common files for -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1289977 Title: Ubuntu 14.04 Update breaks grub, resulting in "error: symbol 'grub_term_highlight_color' not found" To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/1289977/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
