    UEFI


    I am told that UEFI is a huge preventive mitigation against root kits as well, seems worth the extra key strokes to me...

    That only goes for PCs designed for Windows 8 and above that have Safe Boot in the BIOS.

    Windows 7 PCs do not have this and the only advantage UEFI can offer a PC designed for Windows 7 is that by default on a basic MBR disk, you can create a maximum of 4 Primary partitions, or3 Primary partitions and 1 Extended partition with up to 128 logical volumes in the extended partition on a single hard disk, and GPT can have 128 partitions.

    So if the PC is older the only advantage would be if the OP has a NAS or a HDD larger than 2TB and also wants to create special partitions for DATA or games...etc. without Safe boot or fast boot it's not worth the headache. Also it's better to do a fresh install and then any other secondary disk should be formatted to GPT then also.

    This is good to know, thank you! Is there a way to quantize the effectiveness of safe boot? I'd be very interested in stats if they exist somewhere...

    For more on Fast boot.
    For more on Safe Boot(actually called Secure Boot).
    Both at MSDN Blogs.
