How to know the partition where grub is installed

  • 772

I am Dual Booting Maverick with Natty. I want to know which partition has Grub installed.

I want to make sure that grub is installed in the maverick partition not in natty, so that when I remove the natty partition, I don't have booting problem in the absence of grub.

On maverick there is no menu.list file in /boot/grub but natty has one.

Here is the output of fdisk -l

gaurav@gaurav-desktop:~/Desktop$ sudo fdisk -l

  1. One way is to run Boot Info Script. It will return the file RESULTS.txt which will include a line similar to:

    => Grub 2 is installed in the MBR of /dev/sda and looks on the same drive in partition #7 for /boot/grub.
