Start with those two. The simple answer to that is you don't have
multiboot grub module correctly installed. Lots of things can cause
that, but my guess is your installer (Wubi?) does not correctly setup
the boot directory. It only copy the files it seems necessary, while
it should copy all.
The "normal" way to fix this is don't use Wubi. Don't boot from a
loopback in ntfs. It's a somewhat advanced setup, while you don't have
enough experience/knowledge to troubleshoot ntfs-loop-xen combination.
Stick with normal installation methods, using partitions. Or use
virtualbox if you just want to do some tests.

Here's a basic question. Where is your /boot directory located?
If it's on your ntfs partition, does it have /boot/grub? Does it have
/boot/grub/multiboot.mod? It needs it to be able to boot Xen
correctly.

It looks like your grub setup has just enough modules to use loopback
file on ntfs, but the ACTUAL /boot directory is on the loopback NOT
ntfs (hd0,2). Therefore any attempt to read any files from (hd0,2)
simply wont work, cause there's no file there.

Don't use Wubi. Don't boot from a loopback in ntfs. It's a somewhat

Since this is not Xen-specific, but rather wubi - grub - multiboot
issue, you should ask their maintainer/list/forum.
