I've been following instructions on this website to get a bootable USB of Windows 10 so I can install it on another computer. This is essentially what I have done:

  1. Used GParted to create a brand new msdos partition table on the USB (filesystem FAT32)

  2. Used dd to copy over all the contents of the Windows 10 ISO to the USB

    Contents: boot/ , efi/ , sources/ , support/ , autorun.inf, bootmgr, bootmgr.efi, setup.exe

  3. Changed the boot order on the machine to boot from USB first

  4. Just a flashing cursor on a black screen appears, unable to boot

Any idea as to why this could be happening? All my systems are 64-bit, and many websites said to make sure there is a file called "efi/boot/bootx64.efi" because that is needed for booting up, and there is on the USB drive.

I believe the problem is with your step 2. You should not use dd to copy files because it will modify USB filesystem structure.

After you format USB drive to FAT32, copy Windows files using any file manager. That's all you need to make a bootable USB drive from UEFI (provided that Windows supports UEFI, and Windows 10 certainly does).
