RMPrepUSB gives full control over how a USB drive is partitioned, formatted and made bootable, and can test it in QEMU without rebooting.

RMPrepUSB is a software that is specifically designed to help users create and manage a multiboot USB drive. Their website contains a wealth of knowledge on how to get started and use the software including many tutorials. The software can format any USB storage device or USB hard disk as FAT16, FAT32, NTFS or exFAT, and it can also create ext2/3/4 file systems. You can also partition drives and it works on non-USB drives.

The latest stable release is v2.1.746 from May 2022, a small bugfix update. A beta version, v2.2.4, adds GPT drive information and faster testing. RMPrepUSB is free and comes as an installer and as a portable version.

One of the core features is installing boot code, so the drive can start WinPE, Vista or Windows 7 (BOOTMGR), XP or BartPE (NTLDR), MS-DOS, FreeDOS or Syslinux. It can also install grub4dos, clear write-protect flags, check for fake-size drives with the Quick Size Test, measure speed and boot the drive in the QEMU emulator to test it without restarting the PC. The command-line tool RMPartUSB.exe is included.
