Ventoy

This article is a stub. Please help out by expanding it - how to get started.

Resources

Ventoy is is an open source tool to create bootable USB drives for ISO/WIM/IMG/VHD(x)/EFI files. It allows the user to store multiple images, amongst other files, inside a single bootable medium.

Ventoy will create two partitions (EFI and exFAT) on the selected device. The exFAT one will work as regular storage, and will be scanned when booting Ventoy in search of bootable images.

Prerequisites

Overlay

Ventoy is not on Gentoo's main repository, but a binary package is hosted on the GURU overlay.

eselect

Using eselect repository, run this command to add the overlay:

root #eselect repository enable guru

And then synchronize the repository:

root #emaint -r guru sync

Installation

Emerge

Once the GURU overlay is enabled, sys-boot/ventoy-bin can be emerged:

root #emerge --ask sys-boot/ventoy-bin
