Ubuntu – How to manually install GRUB?


I was installing Ubuntu 11.10 and the bootloader install failed. I tried installing it again but it didn't work so I want to know how to install grub manually.

I think this technique will not work. Because you don't know in which position you installer crashed. Check your disk first.

If you want to install grub manually then: Login using livecd. Open terminal, login as root:

sudo -i

find out your linux disk :

fdisk -l

mount it:

mount /dev/sdaX /mnt


grub-install --root-directory=/mnt /dev/sda
