If you have any other operating systems on your system that you wish to keep (dual boot setup), you should make sure that they have been properly shut down before you boot the installer. Installing an operating system while another operating system is in hibernation (has been suspended to disk) could result in loss of, or damage to the state of the suspended operating system which could cause problems when it is rebooted. For information on how to boot the graphical installer, see . &boot-installer-arm.xml; &boot-installer-x86.xml; &boot-installer-ia64.xml; &boot-installer-mips.xml; &boot-installer-s390.xml; &boot-installer-powerpc.xml; &boot-installer-sparc.xml; &boot-installer-accessibility.xml; &boot-installer-parameters.xml; &boot-installer-trouble.xml;
