Easy2Boot is a free, versatile multi-boot USB creation tool with seamless compatibility for both Legacy BIOS and UEFI systems. Its core strength lies in enabling users to effortlessly put multiple OS on a flash drive without the need for repeated formatting—simply copy the image files, and a single USB drive can support booting into Windows, various Linux distributions, and other operating systems. Ideal for both system installation and maintenance scenarios, it stands as an excellent free solution for this exact need.

User Guide

  1. Download and extract: Obtain the latest software version from the official website. Extract the files; no installation is required. Proceed directly to use.

  2. Prepare USB drive: Insert a 16GB+ USB drive (minimum requirement is 8GB; data will be erased, so back up beforehand). Formatting to NTFS is recommended.

  3. Create bootable drive: On Windows, run Make_E2B_USB.cmd from the extracted folder as an administrator. Select the target USB drive as prompted; the tool will automatically install the boot files.

  4. Add system images: Copy downloaded Windows, Linux, or other system ISO/IMG/VHD images directly to the corresponding folder in the USB drive's root directory. The tool will automatically recognise them.

  5. Final steps: Safely eject the USB drive. Insert it into the target computer, enter BIOS/UEFI settings, set USB as the first boot device, and boot to select your desired system.

Pros

  • It fully fulfils the core requirement to put multiple OS on a flash drive, supporting dozens of system images and compatible with multiple formats including ISO, IMG and VHD.

  • Dual-boot mode compatibility seamlessly supports both Legacy BIOS and UEFI, adapting to the vast majority of computers.

  • Eliminates the need for repeated formatting; adding new systems subsequently requires only copying the image, offering convenient operation and saving time.

Cons

  • Higher learning curve than single-system tools, less user-friendly for computer novices; certain configurations require basic command-line operations.

  • Primarily designed for Windows-based creation; operations under Linux/macOS are complex, requiring scripting with generally limited compatibility.

  • Some niche Linux distribution images may not be automatically recognised, requiring manual addition of boot configurations.
