YUMI UEFI

YUMI UEFI is a free multiboot USB creator for Windows that uses GRUB2 to support both BIOS and UEFI booting from a single FAT32-formatted flash drive. It lets you store and boot multiple Linux distributions, Windows installers, antivirus rescue disks, and system utilities from one drive, with a boot menu that appears automatically at startup.

Note: YUMI UEFI is archived and no longer actively maintained. It does not support ISO files larger than 4GB and is not backwards compatible with YUMI Legacy. For actively maintained multiboot USB creation with large ISO support, UEFI compatibility, and persistent storage, use YUMI exFAT instead.

YUMI UEFI – Multiboot USB Maker

YUMI UEFI creates multiboot USB drives configured for systems running UEFI firmware. Because UEFI-based systems require a different boot process and partitioning scheme than legacy BIOS systems, YUMI UEFI formats the drive appropriately and configures GRUB2 to handle both firmware types from a single FAT32 partition.

The drive must be FAT32 formatted to support UEFI booting. YUMI UEFI includes the fat32format utility to format drives larger than 32GB as FAT32, since standard Windows tools limit FAT32 formatting to drives 32GB and under.

Drag and Drop ISO Support

The “Try Unlisted ISOs” option supports drag and drop for ISO files you want to test. Place them in the /multiboot/ISOS folder on the USB drive – they are auto-detected and their entries appended to the boot menu automatically.

BACKUP DATA: Back up all content from every partition on the selected device before using the “Wipe and FAT32 Format” option. The entire disk will be wiped. Diskpart is used to erase the drive and create a single partition; fat32format then formats that partition as FAT32.

SECURE BOOT: Disable Secure Boot in your computer’s BIOS/UEFI firmware settings before attempting to boot from a YUMI UEFI USB drive.

Frequently Asked Questions (FAQ)

What is YUMI UEFI?

YUMI UEFI is an archived multiboot USB creator for Windows that uses GRUB2 to support both BIOS and UEFI booting from a FAT32-formatted USB drive. It is no longer actively maintained and does not support ISO files larger than 4GB. For current multiboot USB creation needs, YUMI exFAT is the recommended alternative.

Is YUMI UEFI compatible with YUMI Legacy?

No. YUMI UEFI is not backwards compatible with YUMI Legacy. If you are switching between variants, reformat the USB drive and start fresh with the new tool.

Can I use ISO files larger than 4GB with YUMI UEFI?

No. YUMI UEFI does not support ISO files larger than 4GB due to the FAT32 file size limitation. Use YUMI exFAT for large ISO support, which removes the 4GB restriction entirely.

How do I format a drive larger than 32GB as FAT32?

YUMI UEFI includes the fat32format utility for this purpose. Standard Windows formatting tools limit FAT32 to drives 32GB and under; fat32format removes that restriction and can format larger drives as FAT32 for UEFI compatibility.

What should I do before using the “Wipe and FAT32 Format” option?

Back up all data from every partition on the selected device before proceeding. The “Wipe and FAT32 Format” option uses Diskpart to erase the entire disk and create a single partition, then formats it as FAT32. This process is not reversible without data recovery tools.

Do I need to disable Secure Boot to use YUMI UEFI?

Yes. Secure Boot must be disabled in your computer’s BIOS/UEFI firmware settings before booting from a YUMI UEFI USB drive. The GRUB2 bootloader used by YUMI UEFI is not signed for Secure Boot.

Can I add ISOs by dragging and dropping?

Yes. The “Try Unlisted ISOs” feature supports drag and drop. Place ISO files in the /multiboot/ISOS folder on the USB drive and they are automatically detected and added to the boot menu on next boot – no re-running the tool required.

Where can I find the latest YUMI UEFI download?

The current archived release and its changelog are available in the download section above. Note that no further updates are planned for this variant.

YUMI UEFI – Key Notes

  • FAT32 required: The USB drive must be FAT32 formatted. YUMI UEFI includes fat32format to handle drives larger than 32GB.
  • 4GB file size limit: FAT32 cannot store individual files larger than 4GB. This limits which ISO files are compatible.
  • Secure Boot: Must be disabled in firmware before booting.
  • Not backwards compatible: Cannot be used on a drive previously prepared with YUMI Legacy.
  • Archived: No longer actively maintained. Bugs may exist that are not fixed in future releases.
  • Recommended alternative: YUMI exFAT supports files over 4GB, persistent storage up to 40GB, drag and drop ISO support, and is actively maintained.
