Why would it not boot?
Because many distributions have trouble booting via UEFI and more and more systems are shipping without legacy/MBR boot support and can only boot via UEFI.
UEFI brings some nice improvements but motherboard manufactures typically only test with Windows and good UEFI support hasn't been a high priority until very recently for many Linux distributions.
Also, Microsoft requires you to successfully install every current update in order to be allowed to upgrade
That is not true at all. If you want to use the option to automatically upgrade to Windows 10 then you do need quite a few updates installed but if you download and use the you can upgrade an existing Windows 7 or Windows 8 install regardless of what updates have or have not been installed.
Indeed, Microsoft recommends that you use the Media Creation Tool on systems that are having problems installing updates or for systems that don't have reliable Internet connectivity. As long as you choose the "Upgrade" option in the installer and the existing Windows 7 or 8 install is activated you won't have to enter a product key.
The more expensive and better quality the camera the less IR is normally let through. Don't confuse looking into the IR spectrum and recording the IR spectrum. They are not done by the same sensor.
Actually IR recordings are typically done with the same image sensor as visible light recordings. What high-quality cameras do is have an IR filter in front of the image sensor that is automatically moved out of the imaging path when the camera is switched into a low-light or nightvision mode (In many cameras this results in an barely audible click when switching modes as the filter is moved).
Such cameras also typically have a collection of ND filters as well that can be switched in and out as needed for filming in very bright light to avoid having to use ridiculously high shutter speeds with a sensitive image sensor.
