If the OP's laptop is Skylake then installing Windows 7 will be really tricky if your laptop manufacturer doesn't offer Windows 7 support. I did a little research on this when my brother-in-law built his custom Skylake gaming rig because he originally wanted Windows 7. It ended up being more trouble than it was worth and he opted to use Windows 10 instead. The problem is that Skylake chipsets treat all USB ports as XHCI (not just the USB 3.0 ports like on older chipsets). Since Windows 7 doesn't have native XHCI support, none of your USB ports will work during the install. This may not be an issue for your laptop if it's like mine and uses PS/2 for the integrated keyboard and touchpad but I'm not sure how Skylake chipsets treat that interface either (Mine is Haswell). Also, your laptop will definitely need to have an integrated SATA DVD drive for the install and you'll need at least the manufacturer's Windows 7 XHCI driver burned on an optical disk to load it and get your USB ports working after the install. If they don't offer Windows 7 drivers for your laptop, you might be out of luck.
