If your screen begins to show a weird picture while the kernel boots, eg. pure white, pure black or colored pixel garbage, your system may contain a problematic video card which does not switch to the framebuffer mode properly. Then you can use the boot parameter <userinput>fb=false</userinput> to disable the framebuffer console. Only a reduced set of languages will be available during the installation due to limited console features. See <xref linkend="boot-parms"/> for details.
