    Currently, I am using Wiindows 7 Home Premium x86 with the drive in MBR partition style.

    I tried to make a bootable USB of latest Windows 10 x86 ISO with Rufus in this configuration:
    GPT partition Scheme for UEFI
    FAT32
    4096 bytes
    Quick Format
    Create extended label and icon files

    When I try to boot from the flash drive, it just goes into a black screen, then returns to the boot menu.

    I enabled both capabilities for UEFI and Legacy boot, UEFI is prioritized.

    What is the problem? Do I have to reformat the drive first to GPT, or it's not supported? Thank you.

    Thanks for the reply. UEFI Secure boot is already off.

    Update:

    I tried making a bootable USB with the same configuration in Rufus, except I made it compatible for Legacy BIOS.
    I successfully booted the USB. But I want to install Windows 10 in UEFI, any solution?

    In the BIOS Settings, booting to both UEFI and Legacy BIOS mode is supported.

    I would leave Rufus alone and manually format the USB drive, extract the files from the .iso image and simply copy and paste the files onto the formatted USB drive.

    open command prompt as admin and run DISKPART


    Code:
    diskpart
    
     list disk
    
     select disk 1 (be sure the disk you select is your usb stick!)
    
     clean
    
     create partition primary
    
     select partition 1
    
     active
    
     format quick fs=fat32     
    
     assign
    
     exit
    This has worked every time for me.

    Maybe your system is not capable to boot win 10 at all, or secure boot is enabled (this prevents you from installing another windows than the original one).

    Why would you want to go to UEFI mode when windows runs just fine on legacy bios mode?

    For every boot it's easiest to just format the USB in FAT32 format and extract the iso to the USB drive, it will boot Bios Legacy AND UEFI both. It can easily be done by explorer.

    Solved:
    While the PC is in UEFI mode, the Windows PE version must match the PC architecture. A PC in 64-bit UEFI firmware mode can only boot 64-bit versions of Windows PE. A PC in 32-bit UEFI firmware mode can only boot 32-bit versions of Windows PE. On PCs that support both UEFI mode and legacy BIOS mode, you may be able to run 32-bit Windows PE on a 64-bit PC by changing BIOS menu settings from “UEFI mode” to “BIOS mode”, assuming the manufacturer supports legacy BIOS mode.

    On my 64-bit UEFI system, I can just either install a Windows x64 in UEFI or a Windows x86 in Legacy BIOS Mode.

    For anyone else. It's not the PC architecture, as the system can run 32 and 64bit due to the CPU. The reason here is the UEFI version.
    Should add windows 32bit can't support 64 UEFI.

    My x86 ASUS Tablet is UEFI bootable, due to its x86 CPU/hardware. But my first answer was just like yours but i edited it because i thought he meant UEFI boot using Win 7 x86 UEFI and AFAIK it's not possible.

    But knowing the pro's for UEFI i still can't think of a reason (when given a choice) to use UEFI/GPT (only if you want to use more than 4 partitions on one hdd or want to install windows on/use hdd's which are 2TB+).

    Well my little buttercup, are you sure you're not running in EFI and are in a pure UEFI state ?.

    You probably have a - 32Mb AMI UEFI Legal BIOS with GUI support.

    There's one other reason, when you have a motherboard with UEFI Ultra Boot, and have a IGPU or GPU with GOP support and have installed in UEFI, you can run Ultra fast boot which bypasses the UEFI postings, and goes directly into windows.

    hands down this is the best solution for creating bootable USB for Windows installations (from Windows 7 and up). Beat Rufus and any other utility. I have been using this method since Windows 7 days, on either UEFI with secure boot or old BIOS systems. It simply works.

    It also simply can be done by using "explorer", just rightclick the usb drive and select format, select FAT32 and give it a name, hit start and you're done ;):)

    Addition to (UEFI) bootable USB and FAT32 format: The biggest file inside the iso (to extract to USB), normally the install.wim file, may not be larger than 4GB (-4kb) to fit the FAT32 format. If wim is bigger then you should split the wim into .swm files (<4GB) or compress it to .esd format.

    Yes, it simply works. Plus you do it yourself, and are not relying on other's software. I use it all the time. It never fails.
