The graphical version of the installer is only available for a limited number of architectures, including &arch-title;. The functionality of the graphical installer is essentially the same as that of the text-based installer as it basically uses the same programs, but with a different frontend. Although the functionality is identical, the graphical installer still has a few significant advantages. The main advantage is that it supports more languages, namely those that use a character set that cannot be displayed with the text-based newt frontend. It also has a few usability advantages such as the option to use a mouse, and in some cases several questions can be displayed on a single screen. The graphical installer is available with all CD/DVD images and with the hd-media installation method. To boot the graphical installer simply select the relevant option from the boot menu. Expert and rescue mode for the graphical installer can be selected from the Advanced options menu. The previously used boot methods installgui, expertgui and rescuegui can still be used from the boot prompt which is shown after selecting the Help option in the boot menu. There is also a graphical installer image that can be netbooted. And there is a special mini ISO image The mini ISO image can be downloaded from a &debian; mirror as described in . Look for netboot/gtk/mini.iso. , which is mainly useful for testing. Just as with the text-based installer it is possible to add boot parameters when starting the graphical installer. The graphical installer requires significantly more memory to run than the text-based installer: &minimum-memory-gtk;. If insufficient memory is available, it will automatically fall back to the text-based newt frontend. If the amount of memory in your system is below &minimum-memory;, the graphical installer may fail to boot at all while booting the text-based installer would still work. Using the text-based installer is recommended for systems with little available memory.
