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.

i success this by copy all files from iso to harddisk and set 'kernel' and 'initrd' (i don't know why it only work from disk's 1nd partiton)
