Boot into a Live CD/DVD/USB of ubuntu.
Then open up a terminal window. run these commands replace /dev/sda with your Drive name.
to find you drive name run this command
sudo fdisk -l
output of the command should look like this:
Disk /dev/sda: 232.9 GiB, 250058268160 bytes, 488395055 sectors
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disklabel type: dos
Disk identifier: 0x0009dcf3
Device Boot Start End Sectors Size Id Type
/dev/sda1 2048 382078219 382076172 182.2G 83 Linux
/dev/sda2 * 382078976 487346175 105267200 50.2G 83 Linux
/dev/sda3 487346176 488394751 1048576 512M 82 Linux swap / Solaris
Where is says Disk /dev/sda at the start of the command that is your disk name. my disk name is /dev/sda when you run the command below copy or type in your device name at the end of these commands
sudo grub-install
then run
sudo update-grub
and then reboot.
