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](https://github.com/siderolabs/talos/releases/latest/).

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](../../getting-started/getting-started).

<Note>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.</Note>

See the [kernel parameters reference](../../reference/kernel) 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](../../learn-more/image-factory))
