What are you using for a bootloader? Grub2? isolinux? Whichever, you forgot to post the menu entry which you are using to try to boot it. We can't tell you what is wrong if we don't know what you've done.

The following entry is one I use to boot SystemRescueCD from a DVD with Grub2:

Code:

menuentry "SystemRescueCD" {
    linux /isolinux/rescuecd
    initrd /isolinux/initram.igz
}

For that to work, you would have to loop mount the SystemRescueCD to another folder, then copy its files to the root of the filesystem. If you have it on a flash drive, you will probably need a drive/partition entry on the loopback loop line as is shown in the Linux Mint entry in the link you posted.

Post your grub.cfg or isolinux.cfg file or whatever you are using.

after posting here i did some search and burn systemrescuecd.iso to cd and found that it was using "rescue64" naming and default entry was this

Quote:

menuentry "SystemRescueCd" {
loopback loop /systemrescuecd.iso
linux (loop)/isolinux/rescuecd isoloop=/systemrescuecd.iso setkmap=us docache dostartx
initrd (loop)/isolinux/initram.igz
}

so i changed to this and now its working..

Quote:

menuentry "SystemRescue CD ISO" {
set isofile="/systemrescuecd.iso"
loopback loop (hd0,1)$isofile
linux (loop)/isolinux/rescue64 setkmap=us isoloop=/systemrescuecd.iso
initrd (loop)/isolinux/initram.igz
}

if possible can you explain me above entry. if i am not wrong rescue64 is kernel which 1st gets load and then initram.igz but i have not understood about loopback working(what i know is it is use for mounting iso's). It would be great if you can add some more light on working of grub2.

sorry for late reply.
