Hi Friends, I am trying to boot ubuntu 12.04 Live cd stored in my internal HDD(not a USB) at root of C partition. (C:\ubuntu.iso)

 

Also, C partition is an NTFS partition.

 

I tried it like this in my menu.lst as:

 

 

title Ubuntu Live
find --set-root /ubuntu.iso
map /ubuntu.iso (0xff) || map --mem /ubuntu.iso(0xff)
map --hook
root (0xff)
kernel /casper/vmlinuz file=/cdrom/preseed/ubuntu.seed boot=casper iso-scan/filename=/ubuntu.iso quiet splash --
initrd /casper/initrd.lz
boot
 
But Grub4Dos says the Device partition is not correct or something like that. 
 
Please Help.

Also Tried it like this:
*********************************************************************************************************************
title Ubuntu Live
map --unmap=0:0xff
map --unhook
root (hd0,0)
map /ubuntu.iso (0xff) || map --mem /ubuntu.iso (0xff)
map --hook
root (0xff)
kernel /casper/vmlinuz file=/cdrom/preseed/ubuntu.seed boot=casper iso-scan/filename=/ubuntu.iso quiet splash --
initrd /casper/initrd.lz
boot
****************************************************************************************************************************
But it just hangs after the line loading initrd. 
I also wanted to ask if we can somehow chainload the isolinux bootloader from the ubuntu iso.

Also, Tried this :

 

title Ubuntu Live
map --unmap=0:0xff
map --unhook
root (hd0,0)
map /ubuntu.iso (0xff) || map --mem /ubuntu.iso (0xff)
map --hook
chainloader (0xff)
 
Now the livecd boots but it shows error like this:
/dev/sr0 not found.
/dev/sdc not found. 
 
Please Help.
