[[!meta title="Bootless: anti-tampering bootloader"]]

**WARNING** - this pre-alpha software with [portuguese-only docs](index.pt)!

* Bootless is a scheme allowing a computer with encrypted disk to stay without attached bootloader in order to make more difficult to tamper the initialization process.
* Bootless is a bootloader installed in a removable media and used to initialize computers.
* It is based on [git-annex](http://git-annex.branchable.com/) and [GNU Grub](https://www.gnu.org/software/grub/).
* Initial support is targeted to Debian like operating systems.
* Bootless currently used in the [Hydra Suite](https://git.sarava.org/?p=hydra.git;a=summary).
