Open IE (desktop) > open 'Google' search page > select 'Tools'' > select "Add site to Start Page'
(You will need to have the 'Menu Bar' displayed.)
You can also access to 'Tools' by pressing 'Alt+T'
My first suggestion required to have "Favourites Bar' displayed
If you open the Google search page in IE Metro, you should remain in the Metro UI and carryout actions as I described.
