[[!meta title="Bootless: barebones tutorial"]]
This tutorial helps you to build a Grub USB stick to boot your operating systems.
Create basic folder structure
-----------------------------
mkdir -p bootless/boot/{grub,custom}
wget https://git.fluxo.info/bootless/plain/templates/grub.cfg -O bootless/boot/grub/grub.cfg
wget https://git.fluxo.info/bootless/plain/templates/custom.cfg -O bootless/boot/custom/custom.cfg
Customize
---------
Please check and customize the downloaded configuration above. The defaults:
* Have examples to help customizations.
* Allows you to load into Grub and boot your OS using the grub shell.
* Provides two functions, `bootfde` and `bootimg` to simplify booting your encrypted system.
You may also place custom images into the USB stick -- with the drawback to have to keep them up-to-date:
cp -r /boot /tmp/bootless/custom/debian
Create a bootable image
-----------------------
grub-mkrescue -o bootless.iso bootless
Record the image into the USB stick
-----------------------------------
**WARNING!** This will irrevocably replace the contents of your USB stick. Pay
attention to get the right device. If your USB stick is attached to your
computer and reachable through `/dev/sdb`, you just have to run
sudo dd if=bootless.iso of=/dev/sdb
