GRUB is a boot loader designed to boot a wide range of operating systems from a wide range of filesystems. GRUB is becoming popular due to the increasing number of possible root filesystems on which Linux can reside upon.

[root@sunny ~]# vi /etc/grub.conf  Your file should show something like this: # grub.conf generated by anaconda # # Note that you do not have to rerun grub after making changes to this file # NOTICE:  You have a /boot partition.  This means that #          all kernel and initrd paths are relative to /boot/, eg. #          root (hd0,0) #          kernel /vmlinuz-version ro root=/dev/sda2 #          initrd /initrd-[gen
