The Anaconda installer includes a range of boot options for administrators, which modify the default behavior of the installation program by enabling or disabling certain functions. To use one or more boot options, you either have to boot from installation media and append these options at the boot menu (see Section 4.2, “The Boot Menu”), or you must add them into your PXE server configuration file if you are booting from a network (see Chapter 10, Setting Up an Installation Server).
You can use multiple options at the same time; in that case, separate them by a single space.
There are two basic types of options described in this chapter:
In addition to the options described in this chapter, the boot prompt also accepts dracut kernel options. A list of these options is available as the dracut.cmdline(7) man page.


Boot options specific to the installation program always start with inst. in this guide. Currently, this prefix is optional - for example, resolution=1024x768 will work exactly the same as inst.resolution=1024x768. However, it is expected that the inst. prefix will be mandatory in future releases.

8.1. Configuring the Installation System at the Boot Menu

The exact way to specify custom boot options is differs based on your system's architecture, firmware and the method you use to boot the installation. If you are booting from local media, you can specify options in the boot menu, before you begin the installation; if you are booting from a network using a PXE server, you must add boot options into the boot loader configuration file before you boot the installation system. For specific instructions, see Section 4.2, “The Boot Menu” if you are booting from local media, and Chapter 10, Setting Up an Installation Server if you are booting from a server.
