Are you targeting or newer machines (UEFI) ? Do you need data persistence (saving files on the live OS)? Which specific operating systems are you planning to carry?

By late 2021, the community emphasized that a "verified" build must account for file integrity. Always verify the SHA-256 checksums of your ISO files before moving them to your multiboot HDD. A single corrupted byte in a 5GB Windows ISO can lead to mysterious installation failures that are difficult to diagnose.

Supports ISO, WIM, IMG, VHDX, and EFI files larger than 4GB. Step-by-Step Configuration

While older methods relied on complex bootloaders like GRUB4DOS or YUMI—which required extracting ISO files and frequently suffered from compatibility issues—the definitive, verified standard for multibooting is .

Historically, creating a multiboot drive required complex partition configurations or tools like YUMI and Rufus, which often required reformatting for major updates.

Once the installation finishes, your hard drive will be split into two partitions:

Here are a few tips and tricks to keep in mind when multibooting:

Ventoy/ ├── 01_Windows/ │ ├── Windows10_21H2.iso │ └── Windows11_21H2.iso ├── 02_Linux/ │ ├── Ubuntu_20.04.iso │ └── Tails_4.20.iso └── 03_Diagnostics/ ├── Hiren_BootCD_PE.iso └── Clonezilla.iso Use code with caution.

What or tools do you need on your drive?

Are you targeting , modern UEFI systems , or a mix of both?

Follow these exact steps to format your drive and install the multiboot architecture safely. Step 1: Backup Existing Data

If you are installing multiple operating systems directly to the hard drive (rather than just using a live USB), follow this verified sequence to avoid bootloader conflicts:

: If you find that adding Windows installers causes conflicts, consider using modern tools like
