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

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

This worked for me, except I have a separate boot partition, so the format wasset prefix=(hd0)/grub, since you need to reference thegrubdirectory 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 bootsda2 linux swapsda3 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
sda1partition and createdsda4ext4 boot partition at the front of the drive and set mount point to/bootafter 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
sda1ext4 partition, it was reported asDOSand had a short 8 character UUID instead of the UUID reported by blkid.grub-probereported the file system as vfat.After many other trials I cleared the first 440 bytes of
sda1partition record.Grub-probenow reports file system as ext2. Ranupdate-gruband the correct UUID for thesda1partition 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.

I found a more comprehensive manual on grub rescue:
https://help.ubuntu.com/community/Grub2/Troubleshooting#grub_rescue.3E-1
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
