So I tried dual booting my desktop today which has windows 7 installed on hard disk one which only contains the windows partition. I tried to install Ubuntu 17.04 on hard disk 2, which is on a 1 tb partition (sdb4). I tried boot repair and it does not seem to have done anything of use. Now when I try to load disk 1 it gives me a error with grub rescue and when I try and load disk2 it goes in a loop where it just keeps rebooting until I stop it. I have no clue where to begin to fix this. Any help at all fixing this would be greatly appreciated. Thanks! Disk 2: Partition 1: 135 mb (Microsoft reserved) Partition 2: 3TB (Basic data partition) Partition 3: 1 mb (Bios Boot) Partition 4: 1 TB (Linux Filesystem)

You can fix your grub using your live CD.

  1. Boot with your Ubuntu live CD again and enter a live session.
  2. Press Ctrl + Alt + T to open the Terminal.
  3. Type sudo update-grub and wait.
  4. Reboot to see if your grub got fixed. If not, try typing sudo grub-install to reinstall the grub.

Edit:

Since you can't update your grub using update-grub, I am giving you a solution (refer to Cannot update grub with parameters on live USB):

After booting the live CD, Mount your Ubuntu partition to /mnt with:

sudo mount /dev/sd*# /mnt

where /dev/sd*# is updated to your Ubuntu partition.

If you have a separate /boot partition, mount it in /mnt/boot as well:

sudo mount /dev/sd*# /mnt/boot

where /dev/sd*# is updated to your /boot partition.

Update grub with the correct root and target:

sudo grub-install --root-directory=/mnt /dev/sdX

where /dev/sdX is the disk(not the partition) where grub is installed.
