Thanks in advance for any help.
I'm running Ubuntu and Windows 7 on separate partitions with a large storage drive to share files between them.
fdisk -l shows:
Device Boot Start End Blocks Id System /dev/sda1 * 2048 209717247 104857600 7 HPFS/NTFS/exFAT /dev/sda2 209717248 419432447 104857600 83 Linux /dev/sda3 419432448 3907028991 1743798272 b W95 FAT32
There's a second GPT backup disk, but it shouldn't be a problem.
Device Boot Start End Blocks Id System /dev/sdb1 1 4294967295 2147483647+ ee GPT
I've just upgraded my 11.10 Ubuntu to 12.04, during the upgrade I got an error about grub being installed on a partition, which I recognised from installing 11.10 and ignored.
However, having completed the upgrade all the Ubuntu entries have disappeared from grub. There are a few linux 3 entries, which don't work and my Windows 7 entry, which I didn't try but I presume still works.
I've booted up the 11.10 live cd and i've tried following this:
however when I get to the part where I run
/etc/grub.d/00_header: 28: .: Can't open /usr/share/grub/grub-mkconfig_lib
I had similar problems when I installed 11.10 but I can't remember how I fixed them >_<
Any advice on what to try next?
