Install Ventoy

Goal: Create bootable USB stick that allows booting from multiple OS images (and still provides scratch storage).

Prep: This was done successfully using a 32GB version of this USB stick (Costco ~~$20 for a two-pack)

Source: Ventoy: Get Started

• For Linux - CLI mode

• the USB drive will be formatted and all the data will be lost after install

• Install Ventoy once, after that all that is needed is to copy the iso files to the USB

  • You can also use it as a plain USB drive to store files and this will not affact Ventoy's function.

• Download the installation package, like ventoy-x.x.xx-linux.tar.gz and decompress it.

• Run the shell script as root

• sh Ventoy2Disk.sh { -i | -I | -u } /dev/XXX

  • Syntax:
    • Ventoy2Disk.sh CMD [ OPTION ] /dev/XXX
      • CMD:
        • -i install ventoy to sdX (fail if disk already installed with ventoy)
        • -I force install ventoy to sdX (no matter installed or not)
        • -u update ventoy in sdX
        • -l list Ventoy information in sdX
      • OPTION:
        • -r SIZE_MB preserve some space at the bottom of the disk (only for install)
        • -s enable secure boot support (default is disabled)
        • -g use GPT partition style, default is MBR style (only for install)
        • -L Label of the 1st exfat partition (default is ventoy)
          - XXX is the USB device, for example /dev/sd
