Build a multiboot USB with Ventoy

Most people make a new bootable USB every time they need a different installer. Ventoy removes that: you install it once, then just copy ISO files onto the drive. At boot, Ventoy shows a menu of every ISO it finds.

What you need

• A USB drive of at least 16 GB (32 GB or more if you want several ISOs)
• The ISO files you want, downloaded from the official project sites
• A computer running Windows or Linux

Installing Ventoy erases the drive. Copy anything important off it first.

1. Install Ventoy to the drive

Download Ventoy from its official GitHub releases page and extract it.

On Windows, run Ventoy2Disk.exe, choose your USB drive under Device and click Install.

On Linux, find your drive first, then run the installer against it:

lsblk                      # find your USB, e.g. /dev/sdb
sudo sh Ventoy2Disk.sh -i /dev/sdb

Double-check the device name. Picking the wrong disk will wipe it.

2. Copy your ISOs

The drive now shows up as a normal partition called Ventoy. Drag your ISO files onto it. That's it. You can add or remove ISOs any time later.

3. Verify your downloads

A corrupted ISO is the most common cause of failed installs. Compare the checksum with the one published on the download page:

sha256sum ubuntu-24.04-desktop-amd64.iso

4. Boot from it

Restart the target machine and open the boot menu. The key is usually F12, F11, F9 or Esc, depending on the brand. Choose the USB drive, then pick an ISO from the Ventoy menu.

Troubleshooting

• Drive not in the boot menu: try a different USB port, or enable USB boot in the BIOS/UEFI settings.
• "Verification failed" with Secure Boot on: Ventoy supports Secure Boot, but you need to enroll its key the first time. Follow the on-screen prompt, or temporarily disable Secure Boot.
• An ISO won't boot: re-download it and verify the checksum.
