"Systems with an nVidia graphics card: These systems boot the live
session by default with the open source video driver 'nouveau'. On some
hardware this driver may crash which results in a freeze of the
graphical session of the installer. If it happens, on the boot menu,
select a 'Safe graphics mode' entry. Then in the installer, on the
'Preparing to install ...' page, select 'Install third party software
...' and continue. This option will install the nVidia proprietary
drivers on the target system. Upon installation the proprietary drivers
for your card will be loaded and the graphical session should work
properly with optimized drivers."
