    Partition confusion, MBR / GPT, Windows installation caused problem

    Hi, Windows 10 Home 64 bit Clean install, 2 Samsung 850 EVO's, one will be main drive the other for backup purposes. The screen shot below was taken from Macrium Reflect backup / restore software. Both SSD's seem to be functioning well, load very fast, no operation issues that I know of. My question is concerning how the Disk's are labeled / formatted / partitioned. Is this normal or did I do something go wrong? I have never formatted / partitioned a disc. I have installed new disc's, loaded the operating system and all was well. Windows 10 apparently has something new going on I an not familiar with. The Seagate FreeAgent will be replaced by one of the new SSD's. Please advise. While I am not "tech savvy" as most of you are I do "OK". Please communicate in laymens terms so I can better understand.

    Thank You

    As far as functionality once booted into Windows. They are both OK. It just depends on how you install Windows. In the installation Media, from the boot menu, there are two options to install Windows: 1- Install Windows with GPT disk partition scheme, 2 - Install Windows with legacy MBR Partition scheme. So if you left the disk unallocated at the time of install and pick one of the two, Windows will initalize the disk accordingly. In addtition, the BIOS must be set either to UEFI or MBR.

    BIOS set to UEFI then you must select # 1 in the screen shot
    BIOS Set to MBR then you must select # 2

    More info about the differences between the 2's:

    The two options are shown below with my MB Boot Menu. Yours might look different,

    In most cases, it will be fine with either MBR or GPT. It is only in situation where you need to install Windows on a Mac, or when you need to have a partition bigger than 2TB, that you need to use GPT, or convert MBR to GPT. Also, for the newer model of computer that uses UEFI, it will only support GPT.

    Thanks, When I installed I used an ISO file downloaded from Microsoft and burned to DVD. During the install process I was asked to choose where to install. There were several options but Windows said I could not install on any of the options. Never experiencing that, and not knowing what to do I deleted all of them and then only one choice was available and Windows accepted it. That happened on both SSD's. F12 is supposed to allow me to select my boot device but it does not work. Non of the F keys work during boot, only Delete to get me into the Bios which is where I select my boot order. I can I get a screen shot like you have?
