wubi missing module multiboot to boot with Xen

[Abhishek Dixit]

Continuing in same thread where we are trying to debug a grub problem
on a machine where Ubuntu
 was installed using Wubi in C driver of Windows 7 C:\ubuntu
following are the grub entries we need to boot

menuentry "Xen Linux 2.6.32.27" {
     insmod ntfs
     set root='(hd0,2)'
     loopback loop0 /ubuntu/disks/root.disk
     set root=(loop0)
     multiboot /boot/xen.gz
     module    /boot/vmlinuz-2.6.32.27 dummy=dummy root=/dev/sda2
loop=/ubuntu/disks/root.disk ro console=tty0
     module    /boot/initrd.img-2.6.32.27
}

with above entries I was getting

error:file not found.
when booting and command multiboot ,module are not present.


Now to dig this issue further I reboot the machine and go to grub command prompt

and manually pass on each of the above parameters which you see in the
grub entry
when I reached
grub> insmod multiboot
then I got following message on screen
error:file not found.

As Phillip suggested
set prefix=(loop0)/boot/grub

I tried putting above line at many different places which included
before I gave command
insmod multiboot
and I am getting the same file not found error.

Any further things that I may look into?
