boot direct from an iso

[ago]

Hi all,

The feature was "removed" in hardy in order to simplify options, and
because a few users were confused by the read only environment.

I used quotes since that only ivolves a change of boot parameters. If
you install wubi normally, before rebooting look at the last option in
/ubuntu/install/boot/grub/menu.lst

Please let me know if you need further help.
