UEFI and dual-boot?

What's the current state of dual booting (particularly Debian (Wheezy) and Win8) on UEFI ("Secure" boot) PCs? In particular, with say a Toshi L850/046 with Win8, can I reasonably expect success shrinking the existing partition and installing Debian in a separate partition and ending up with a workable dual-boot system? Pointers to HOWTOs etc gratefully accepted (I've searched, but didn't come up with much yet, apart from the discussion here in early Jan and an article on Matthew Garrett's Shim[1]). Thanks, Neale.
