After update, get “error: file not found.” followed by “grub rescue> _”
I just installed quite a lot of 12.10 updates, was prompted to reboot, and then found that I couldn't boot.

Since I'm not yet allowed to add comments since my low reputation I add the comment this way... I used 8128s Answer wit Boot-repair but I had to add this line before the apt-get update sudo sed 's/trusty/saucy/g' -i /etc/apt/sources.list.d/yannubuntu-boot-repair-trusty.list like you see in the link he added to the answer

Use Boot Repair to fix your bootloader.
- Boot Ubuntu from a LiveCD or Live USB
- Connect to the internet
Open a terminal, and add the Boot Repair PPA
sudo add-apt-repository ppa:yannubuntu/boot-repair && sudo apt-get update
Install Boot Repair
sudo apt-get install -y boot-repair && boot-repair
Launch and use, see https://help.ubuntu.com/community/Boot-Repair#Using_Boot-Repair for more details
I had to run 3. as root (sudo su) instead of just sudoing

- Type
ls
to get a list of partitions - Enter
set prefix=(hd0,msdos6)/boot/grub
[you will almost certainly have to enter a different drive/partition in the brackets, you may just have to try all of those listed byls
until you find the one that works. - Type
insmod normal
- Type
normal
and you will get your boot prompt back!
See also: The helpful place where I found this. I doubt this will work for everyone encountering this error, but I've put it here in the hope it helps someone.
Once you've loaded Ubuntu, run sudo grub-install /dev/sda
and sudo update-grub
as soon as possible. This means you won't have to do that tedious process above every time you boot your machine.

You can also use the commandls (hd0,msdos1)/
to check the contents of the partition, which would be faster if you have many partitions.
– Jonathan

This worked for me, except I have a separate boot partition, so the format wasset prefix=(hd0)/grub
, since you need to reference thegrub
directory relative to the partition on the drive, not relative to its mount point during normal operation.

I had the exact same issue - normal.mod not found
, ls
of the boot partition would produce a blank line. After a week of troubleshooting to get the system to boot properly here are the steps I went through.
Got a copy of SuperGrub and created a boot cd. I could now get logged back on to my system. Got a copy of BootRepair and had not luck getting the system to boot directly from the hard disk and had to keep using the CD. BootRepair did act a little strange since the Grub location and Grub options were grayed out. It did report a successful install.
Hard drive was originally set up:
sda1 ext4 root with boot
sda2 linux swap
sda3 ext4 used as a spare drive
(holds VMs for Virtual box).Used a copy of Ubuntu 10.10 live cd. Ran gparted to shrink the
sda1
partition and createdsda4
ext4 boot partition at the front of the drive and set mount point to/boot
after deleting the boot directory from/
. BootRepair now has options available. Installed on boot partition and can now boot from hard drive.Being curious I decided to investigate further. The boot repair log had a peculiar entry for my
sda1
ext4 partition, it was reported asDOS
and had a short 8 character UUID instead of the UUID reported by blkid.grub-probe
reported the file system as vfat.After many other trials I cleared the first 440 bytes of
sda1
partition record.Grub-probe
now reports file system as ext2. Ranupdate-grub
and the correct UUID for thesda1
partition appears.
The issue seems to be two-fold:
1. It seem to affect installations where the partition record has references to msdos.
2. grub-probe
does not try to resolve mismatch issues between fs type and contents in the partition record.

Got a copy of SuperGrub and created a boot cd. I could now get logged back on to my system. Got a copy of BootRepair and had not luck getting the system to boot directly from the hard disk and had to keep using the CD. BootRepair did act a little strange since the Grub location and Grub options were grayed out. It did report a successful install.

In my case, I had downgraded to GRUBv1 and after the upgrade to 12.10 grub2 couldn't find his files (*.mod, etc...), although the grub.cfg was there.
I found a more comprehensive manual on grub rescue:

See also the command list at the begining of the page.
Thx flute flute.

Thank you for your interest in this question.
Because it has attracted low-quality or spam answers that had to be removed, posting an answer now requires 10 reputation on this site (the association bonus does not count).
Would you like to answer one of these unanswered questions instead?
Since I'm not yet allowed to add comments since my low reputation I add the comment this way... I used 8128s Answer wit Boot-repair but I had to add this line before the apt-get update sudo sed 's/trusty/saucy/g' -i /etc/apt/sources.list.d/yannubuntu-boot-repair-trusty.list like you see in the link he added to the answer
