Part 4: Create Bootable USB Drive from Multiple Windows ISO Files

RMPrepUSB helps you format drives and burn multiple bootable ISO files on a single drive. It's useful for when you need the same drive to contain different versions of Windows. The biggest drawback, however, is that it is built for pre-Windows 10 bootloaders. It works well with Windows XP, Windows 7 and Windows 8.

Interestingly, RMPrepUSB was originally written for the purpose of wiping, partitioning and formatting USB drives, but it has evolved into a much larger software with multiple features.

Step 1: The first step is to download the RMPrepUSB zip file, extract the .exe file and run it to install the software on your Windows PC. Then launch the application and follow the instructions provided below.

Step 2: To format the drive, there are five parameters that you must enter:
Partition size - set as MAX for maximum allowable partition size
Drive name - specify a name for your drive
Bootloader options (select the first option for Windows installations)
File system - for smaller USB drives use FAT16; for larger ones over 16GB, use NTFS.

Step 3: Finally, click on 'Prepare Drive' to format it and add the bootable ISO file.

Cons:

  • Complex settings and user interface.
  • Not supporting Windows 10 ISO .
  • Take a lot of time to find the correct user manual.

Conclusion:

RMPrepUSB utility is clearly not for everyone. If you have no experience handling disk images, then we recommend using Method 2 described above. UUByte ISO Editor does not require any sort of technical expertise, and the software comes with superb technical support if you get stuck at any point. With most other bootable media creation software, you'll come across issues like drive not found, file system incompatibility or other problems. Not with UUByte ISO Editor.
