Hello!
This is obvious, but the only limitation is that your Windows install must be set up to use UEFI first. Since you install a legacy LL and 'shim' the UEFI version of GRUB in later, UIAM, you shouldn't have any problems with doing it at any time after the legacy LL installation. Of course, you'll also have to select legacy boot when booting into the LL LiveUSB.
You'll also need a UEFI version of Ubuntu (14.04.2 will do). I mounted it in a virtual drive in Windows 8, copied all the files over to a flash drive, and set my BIOS boot manager to boot from the UEFI USB.
Go to the actual YouTube page for the video posted here and read my comments, to avoid a common pitfall involving a space at the end of a line that wraps around to the next line, since you can't cut-and-paste out of the video itself...

A gun in your hand is worth more than a whole police force on the phone.
