CluelessPerson: you should locate your iso first by doing this

ls

ls (hdX,Y)

for example :

ls (hd0,1)

 

now to the main linux partition..

assuming it is: hd0,1

 

assuming your installed linux partition is hd0,1

assuming your iso lives in hd1,1

type this :

 

set prefix=(hd0,1)/boot/grub

 

insmod linux

insmod loopback

insmod iso9660

insmod fat

insmod ntfs

insmod nftscomp

 

 

loopback loop (hd1,1)/<path to ISO>/<ISO-name.iso>

 

set root=(loop)

linux /casper/vmlinuz boot=casper iso-scan/filename=/<ISO-name.iso> noprompt noeject

initrd /casper/initrd.lz

 

boot

 

---------

 

if it boots,

 

sudo blkid

 

assuming it is /dev/sda:

 

sudo grub-install --boot-directory=/mnt/boot /dev/sda

 

sudo update-grub
