Before you install
Read the release notes and installation guide before downloading. Select an image that matches the processor architecture and intended use: desktop, server, live media, virtual machine or another published edition. Test Wi-Fi, graphics, audio, storage and suspend from live media when that option is available. Back up important files before repartitioning, encryption changes or dual-boot installation. Security distributions should only be used against systems and networks you own or are explicitly authorized to assess. Download from an official project page or mirror, compare the published SHA-256 checksum, and verify a signed checksum when the project provides one. After installation, apply updates before adding third-party repositories or drivers.
- 1Check the SHA-256
Compare the file with the checksum published by Pentoo. If it does not match, download it again.
- 2Write it to a USB drive
Use Ventoy, balenaEtcher, Fedora Media Writer or Rufus. Copying the ISO as a normal file does not work.
- 3Boot from the USB
Open the boot menu (often F12, F10 or Esc) and choose the USB drive in UEFI mode. Back up your data first.
About Pentoo
Pentoo is a Gentoo-based live and installable environment for penetration testing and security assessment. The selected amd64 hardened image is the 2026.0_p20261109 build listed in the official Release directory. The project distinguishes Release, Beta and daily images; the older version text on its general download page does not describe this selected file. Consult the project documentation for installation and updating.
Who is it for?
Pentoo is primarily suited to authorized security testing, forensics and technical training; experienced Linux users who want detailed control over the system. Before choosing it, compare the current release lifecycle with the length of support required for the machine. This distribution is based on gentoo, which influences package formats, repositories and much of the available documentation. The listed desktop environment is Xfce; confirm its memory, graphics and accessibility requirements on the official project site. The best choice depends on hardware support, preferred software, update policy and the amount of system administration the user wants to perform.
Advantages and limitations
Advantages
- Provides specialist tooling for authorized security, forensics or defensive work.
- Benefits from the package ecosystem and documentation associated with its gentoo lineage.
Limitations
- Installation or administration may require more Linux knowledge than beginner-focused systems.
- Specialist security images are not always the best choice for an ordinary daily-use desktop.
Pentoo download questions
Which Pentoo ISO should I download?
IsosLinux lists the desktop ISO for laptops and PCs, with a live session and graphical installer. Most people installing on a computer want the desktop ISO. Other editions and architectures are listed under All images.
Is the Pentoo download official?
Yes. The download buttons open files on www.pentoo.ch, the project's own server or official mirror. IsosLinux only lists the link and counts the click; it does not host or modify the image.
How do I check that the Pentoo ISO is not corrupted?
Compare the SHA-256 checksum of your file with the one published by Pentoo. On Linux run sha256sum on the file, or use the IsosLinux ISO checksum verifier, which works locally in your browser.
What is Pentoo based on?
Pentoo is based on gentoo, so most software and guides for gentoo also apply.
Which desktop does Pentoo use?
The default desktop listed for Pentoo is Xfce.
