Install Ubuntu 13.10 via Grub Legacy

I need to install Ubuntu 13.10 into an old Linux machine. The BIOS has been locked such that I cannot boot from CD or USB drives.

The machine has grub 0.97 and a pretty old CentOS installed on it, which I've got the root access, so I decided to try to load the ubuntu iso file with it.

I tried to enter the grub commands there, but then it failed with error like this:

stdin: error 0
/init: line 7: can't open /dev/sr0: No medium found
After spending hours in searching and trying, I found this url: http://askubuntu.com/questions/47076/usb-boot-problems
which solved the problem for me.

The full commands I used are:

root (hd1,0)
kernel /casper/vmlinuz.efi boot=casper live-media-path=/casper/ ignore_uuid
initrd /casper/initrd.lz

This link http://manpages.ubuntu.com/manpages/karmic/man7/casper.7.html
describes the parameters for casper
