You can re-install grub as follows: from a live CD
- Code: Select all
sudo mount /dev/sdXY /mnt
replace X and Y with the appropriate drive and partition for Mint boot partition.
- Code: Select all
sudo grub-install --root-directory=/mnt /dev/sdX
note - there's a gap between =/mnt and /dev, and no partition number after sdX
re-boot into Mint then
- Code: Select all
sudo update-grub
Next time you turn on your PC you should see a grub screen giving the option of booting to Windows or Mint.
