GRUB (GRand Unified Boot) loader is a boot loader for multiple operating system. It is one of the most popular bootloader for GNU/Linux operating system (the other is LILO). GRUB flexibility and easy-to-configure boot parameter has made it the default choice for most of GNU/Linux distros.
This article highlights yet another GNU GRUB usefulness in booting GNU/Linux inside a portable USB Flash drive : Installing GRUB on a USB flash memory key
Installing grub in a flash drive:
Execute the commands that follow as ROOT
user@user-pc $sudo -s
[sudo] password for user:*******
(*****) is your password,
then,
1)Use fdisk -l to find the mount point of the drive
2)On my computer the flash drive is mounted on /dev/sdb1
3)root@user-pc:# mount /dev/sdb1
4)mount –bind /proc /mnt/proc
5)mount –bind /dev /mnt/dev
6)mount –bind /sys /mnt/sys
7)chroot /mnt
8)update-grub2
9)grub-install /dev/sdb
hope that helps
