Talos can be installed on bare-metal machines using an ISO image. ISO images for amd64 and arm64 architectures are available on the Talos releases page. When booted from an ISO, Talos does not install itself to disk until a machine configuration is applied. For steps on how to install Talos, follow the getting started guide.
If a Talos installation already exists on the disk, the machine will boot into that installation even when booting from a Talos ISO. The boot order should prefer disk over ISO, or the ISO should be removed after installation to ensure Talos boots from disk.
See the kernel parameters reference for a list of kernel parameters supported by Talos. Two flavors of ISO image are available:
  • metal-<arch>.iso supports booting on BIOS and UEFI systems (UEFI only for arm64)
  • metal-<arch>-secureboot.iso supports booting on UEFI systems in SecureBoot mode only (via Image Factory)
