    Hi theog!

    When I read your question the first time, I was wondering why did you ask that. But after a little research, it seems that USB 3.0 ports need an OS to function properly. At least that was I understood from this post:

    Windows 7 on these hardware.


    Under Format Options, check Quick format.
    Is it better to uncheck these? thx

    If you are using a flash drive, no. All this does is fill all sectors of the drive with zeroes, which is a very slow operation that will also reduce the life of your drive, as flash memory (especially the one in cheap flash drives) has a much more limited number of write cycles before failure compared to regular HDDs.

    Unless you have a need to erase any trace of your old data (which isn't something that this method will guarantee as flash drives are known to reorganize sectors around, and could remap existing sectors as spares that won't be erased), unchecking the option is pointless, which is why it is selected in Rufus by default.

    I'm trying to install Windows 10 64bit on my UEFI motherboard.

    I created my Win 10 installation USB drive using Rufus and created the drive using the GPT partition scheme with 32bit file system.

    I configured my internal HDD with the GUID partition scheme.

    When I boot from the USB drive everything seems to be going fine until I get to the point of choosing the HDD to install to, then the installation stopw with the error message that the HDD has the MBR partition scheme even though I partitioned it with GUID.

    Why is the installation not seeing the correct partition scheme?

    Please realize that the GPT partition scheme you select in Rufus applies only to the USB you boot from, not the internal HDD you install Windows to.

    Whatever you select in Rufus becomes completely irrelevant once the Windows installer has booted (though it may help to ensure that Windows boots in UEFI mode and not in BIOS mode). Especially, it's not because you selected GPT in Rufus that the Windows installer will automatically use GPT for the partition scheme.

    You probably need to clear/repartition your HDD (which seems to be MBR - and Rufus cannot change that on its own) from the Windows installer so that it will be converted to GPT. But this is a Windows installer issue, not a Rufus issue.

    Your trying to use a 32 but OS in UEFI that's not going to work UEFI requires 64bit OS After making your 64bit install USB with Rufus or Windows tool use diskpart to clean your hard drive then let the Windows install create the needed partitions to run UEFI GPT

    I was installing the 64bit version.

    I had made the mistake of formatting and partitioning the drive to FAT/GPT before I started the Win 10 installation which in my case did not work.

    So, during the installation I started a command prompt and ran 'diskpart', identified my drive and used the 'clean' command to prepare the drive. This time the partition was recognised and the installation proceeded without a hitch.

    I still don't know how a previously prepared drive created with the GPT partition scheme was recognised by the Win 10 installer as MBR?

    The problem when you talk about "drive" is we don't know if you're talking about your USB drive or the internal HDD drive that you are installing Windows onto. These are 2 completely separate disks, and the only one that matters for Windows, in terms of partition scheme, is the HDD.

    So when you say "a previously prepared drive created with the GPT partition scheme" I have to assume that you are talking about the USB drive, which, as far as Windows is concerned, and as I previously explained, is completely irrelevant to the Windows installer process, since it is NOT the disk you're installing Windows onto. It could be using a wild file system and your own custom partition scheme, and the Windows installer would be just fine as long as it can boot and read the installation files from it. So the fact that that drive is GPT is completely irrelevant to the whole installation process.

    The only thing that matters to Windows is the target drive, i.e. the internal HDD. When Windows complains that it's unhappy with that drive because it's using the MBR partition scheme, I believe it, because if the only thing you did was create an USB installation drive in Rufus, you certainly did not change the partition scheme from that drive, which was probably MBR. And this is further corroborated by the fact that after you applied the 'clean' command to your installation HDD (which does remove the partition scheme), the installer was fine, since it could now create the partition scheme it wanted on that drive.

    So really, everything you are stating above makes sense, unless you are indicating that you did attempt to manually change your target HDD to GPT partition scheme. But if that's the case, then you clearly did something wrong, since that's not what the Windows installer saw as being used by your target drive until you used diskpart.

    32 bit and GPT are incompatible Your USB should have been formatted Fat 32 your Target hard drive should have been cleaned and converted GPT or just left clean.

    I configured my internal HDD with the GUID partition scheme.

    Again Target HD should be Clean or Clean and converted to GPT

    When I boot from the USB drive everything seems to be going fine until I get to the point of choosing the HDD to install to, then the installation stopw with the error message that the HDD has the MBR partition scheme even though I partitioned it with GUID.

    Yes FAT is for BIOS and GPT is for UEFI, both Systems you either have one or the other for OS HD/SSD . In you case your HD remained FAT

    So, during the installation I started a command prompt and ran 'diskpart', identified my drive and used the 'clean' command to prepare the drive. This time the partition was recognised and the installation proceeded without a hitch.

    You solved the problem By entering Diskpart and Cleaning your HD which allowed the windows install to create the UEFI needed partitions

    I still don't know how a previously prepared drive created with the GPT partition scheme was recognised by the Win 10 installer as MBR?
    Yes were all either just learned or are learning this new UEFI system it is a much better system than BIOS/MBR but a little tricky to install to until you understand the way of it. https://en.wikipedia.org/wiki/Unifie...ware_Interface explains the system technically.

    Hi

    Thanks for the reply.

    My system is UEFI. When I created the USB Win 10 installer (drive, stick, device ,medium I never know what to call it) I created it on a Windows machine using Rufus, this creates a (I'll call it a USB stick) with the GPT partition scheme and the FAT filing system. This is fully recognised by the machine and installation proceeds as normal.

    When I choose a HDD for the installation of Win 10 I first installed the drive in a Hackintosh machine and used OS X El Capitan 'disk utility' to partition the new HDD with the GUID (GPT) partition scheme with the FAT file system The same as the USB stick, I then removed the newly created HDD and installed it in the new machine and ran the Win 10 installer which told me the HDD had a MBR partition scheme.

    When I re-installed the HDD in the Hackintosh disk utility reports the HDD as having the GUID partition scheme??

    Next time I will leave the target HDD alone and let the Windows 10 installer sort the drive out.
