Does anyone know of an Easy solution to dual boot Window and Ubuntu with UEFI after you have already installed Ubuntu or for that matter from the get-go? I have tried enabling CSM in my BIOS and using it for Windows but Windows runs really slow cause I guess it requires UEFI for 64 bit applications. All the posts and tutorials on this are real confusing so if you can't make this for a laymen to understand, I guess Windows has just won this battle.
