GRUB is the boot loader available on GNU project under the Linux operating system. GRUB provides users with the flexibility to choose which OS to boot from a list of OS on a system as well as to select the relevant kernel configuration for that particular OS.

All the manipulations have to be done as root by accessing the menu.lst file. Once the configuration file is open, one can edit the entries using the insert mode. After that it is easy to remove these unwanted commands from the GRUBMenu.
