How to Add Multiple ISOs to One USB with YUMI exFAT [2026]

Unlike tools that require reformatting your USB drive for every new ISO, YUMI exFAT lets you stack multiple bootable operating systems and utilities on a single drive.
 

The exFAT version handles large files over 4GB - essential for modern Windows 11 ISOs that exceed the FAT32 file size limit.

Adding Multiple ISOs

Select your prepared USB drive.

Launch YUMI exFAT and choose your USB drive from the dropdown list.

Make sure you've already formatted the drive with exFAT during initial setup.

Choose your next ISO file.

Select another ISO from your collection - this could be a Windows installer, Linux distribution, or antivirus rescue tool like Kaspersky Rescue Disk.

YUMI supports hundreds of distributions out of the box.

Configure persistence (optional).

Some Linux distributions support persistence, which saves your changes between sessions.

If available for your selected ISO, set the persistence slider to allocate storage space for saved files and settings.

Click Create to add the ISO.

YUMI writes the ISO to your USB drive without touching existing bootable entries.

Your previous ISOs remain intact and fully functional.

Repeat for additional ISOs.

Add as many bootable tools as your USB drive capacity allows. Each new ISO appears in the boot menu automatically.

Pro Tip: Drag and Drop Method

For even faster additions, simply drag ISO files directly into the YUMI folder on your USB drive.

YUMI's boot menu automatically detects and lists these extras without running the application again.

This works great for quickly adding rescue tools or diagnostic utilities.

Recommended ISOs for Your Multiboot USB

A well-rounded multiboot USB typically includes: 

• a Windows installer for system recovery,
• a lightweight Linux distribution like Ubuntu or Linux Mint for troubleshooting,
• an antivirus rescue disk for malware removal,
• and a disk utility like GParted for partition management.

Alternatives to Consider

For simpler single-boot USB creation, Rufus remains the fastest option.

If you prefer a format-free multiboot solution, Ventoy lets you copy ISOs directly without any special software.

Users installing Windows 11 on older hardware should check out FlyOOBE for bypassing TPM requirements.

For creating and editing ISO files before adding them to your USB, UltraISO handles all major image formats.
