Comment 1 for bug 289791

This is due to the fact that grub-installer sets the timeout to 10 seconds if other OSes are discovered. Of course in the Wubi case, menu.lst is used as second boot menu, so that a user has already a chance to change the OS in the first boot menu and hence the 10 seconds delay is not justified in this case. This was discussed briefly on IRC some time ago' but it was decided that special-casing that was probably not worth it.
