    I tried creating an MBR partition table with GParted, then I followed your instructions in Diskpart to create the FAT32 partition, and copied the contents of the .iso onto the USB drive.

    I'm still not seeing the device in the Boot Manager menu.

    I can run the 64-bit version of GParted, so I'm assuming it does support 64-bit OSes.
    I have a tablet with somewhat newer Intel Atom CPU than your tablet, based on if I read the model correctly in your screenshot in post #2. Although these tablet Atom CPUs are x64 based, they can only run 32 bit Windows. I have experienced exactly the same than you, not being able to boot the device from 64 bit Windows install USB, having no issues with 32 Windows install media.

    I am quite convinced that your issue would be resolved simply by creating a 32 bit USB media and booting from it.

    I ran the CLEAN command, as seen below:
    That's odd, I used the commands for real to generate my earlier post. I repeated them having first converted the usb to gpt. They were sufficient to wipe all info and return the usb to an mbr layout.

    Try adding the command CONVERT MBR immediately after CLEAN.

    edit: I've managed to make my usb behave like yours. This time I used diskpart (instead of MiniTools Partition Wizard)to convert it to gtp before testing my commands. Repeating them with the CONVERT MBR command added successfully set the partition as Active at the end.

    PolarNettles, my iso does not have the \EFI\boot\bootia32.efi file.
    I meant on the GParted USB.

    There's 2 steps to boot the OS:
    1. UEFI->bootloader (bootia32.efi/bootx64.efi)
    2. bootloader->kernel

    For some Atom-based systems, the UEFI only supported 32-bit bootloaders (step 1).

    For Linux, the 32-bit GRUB bootloader can still load a 64-bit kernel (step 2).

    Windows does not support this. A 64-bit installation ISO only has the 64-bit bootloader. As Kari said, at this point you might as well just try the 32-bit Windows ISO.

    First, try to use newer Rufus. In Rufus, change Partition Scheme and File System according to the picture. If all else fails, disable Secure Boot and add BIOS Boot (in BIOS/UEFI settings) if possible.

    Using a 32-bit version of the Windows 10 installer ISO seems to have fixed my boot issues! I am using both Rufus as muchomurka suggested, and Bree's Diskpart method, to boot into the Installer.

    Why did I test both methods? Well, that's where the new problem I'm having comes in. When I try to actually perform the install of Windows 10, I get this error:

    Windows cannot install required files. The file may be corrupt or missing. Make sure all files required for installation are available, and restart the installation. Error code: 0x80070570.
    I get this error with both methods of USB creation (Rufus and Diskpart).

    The name of the 32-bit ISO is:

    en_windows_10_education_version_1703_updated_march_2017_x86_dvd_10188968.iso
    Should I create a new thread for this new problem?

    EDIT: Here's the hash of the ISO:

    fciv en_windows_10_education_version_1703_updated_march_2017_x86_dvd_10188968.iso
    //
    // File Checksum Integrity Verifier version 2.05.
    //
    b17a423fe652ca2156922884c2fedade en_windows_10_education_version_1703_updated_march_2017_x86_dvd_10188968.iso

    I'm not sure of the reliability of this particular source, but this page has the same hash listed above for the version I'm using.

    There are a number of possible causes for 0x80070570, looks like you've eliminated the corrupt install media one with all the making and re-making you've done :) but if you want to be really sure, you could try using a completely different route to make the install usb (one last time). Try using the Media Creation Tool to 'make media for another PC' and make another usb. Warning: the MCT fails if the usb you give it has a gpt partition, the MCT requires an mbr usb. See post #30 here.

    Will MCT work for the Education version of Windows 10, which is the only version I have a valid key for?

    Yes, the install media it makes includes Education, and many other editions too (10 S, Home, Pro, Home Single language, and their 'N' editions).

    It's an 'all purpose' install media, you choose which of its many editions to use at install time.
