- Modifying the boot options using the Boot Loader
The Boot Loader is the first screen that appears when Tails starts.
You can use the Boot Loader to modify the boot options. Boot options are special parameters used to troubleshoot or work around hardware support problems. For example, our list of known issues with graphics cards documents boot options for different graphics cards.
