grub
how do i reinstall grub? i finished installing everything on my hard drive and i would like to redo the grub installer to make sure that i have everything that i should on it
I am not sure to understand your problem. However, it does not seem you actually need to reinstall GRUB. To reconfigure it, you can execute:
$ sudo dpkg-reconfigure grub-pc
I think magic banana is right. Do you actually find some item missing in Grub? If after installing Trisquel it has recognized all your operating systems -provided you have more than one on different partitions- you only have to run "sudo update-grub" (without quotation marks) to make sure that your "running" Grub includes new kernels after eventual updates of the other OS's.
