To run the emulation software of the live-CD, the computer must boot from the live-CD. You will need to restart your computer and run the live-CD before the computer defaults to its standard operating system. In the last couple of years, most PC's come with a boot menu that can be called at start up. Using this menu, you will tell the computer to boot from the CD drive. Some older computers automatically look to the CD drive before they look to the hard drive. Finally, a smaller number of PC's may require alteration of the BIOS at start up.
Simple Booting for Dell Computers
(1) Place
our live-CD in your CD/DVD drive then shut down your computer.
(2) Restart (power up).
(3) As soon as the computer displays the Dell splash screen push F12 and the boot menu will appear.
(4) Using arrow or tab key to scroll, select CD as the choice for
booting.
(5) Press Enter and patiently wait for the linux system to
boot.
Simple Booting for HP Computers
(1) Place
our live-CD in your CD/DVD drive then shut down your computer.
(2) Restart (power up).
(3) As soon as the computer displays the HP splash screen push F9 and the boot menu will appear.
(4) Using arrow or tab key to scroll, select CD as the choice for
booting.
(5) Press Return/Enter and patiently wait for the linux system
to
boot.
Simple Booting for Other PC's (non-Apple)
(1) Place
our live-CD in your CD/DVD drive then shut down your computer.
(2) Restart (power up).
(3a) Some computers automatically look to the CD drive before looking to the hard drive. If you have one of these computers, the Supercomputing Simplified splash screen will appear immediately and without any further effort on your part. Press Return/Enter and patiently wait for the liveCD system to boot.
(3b) Computers with a boot menu will tell you how to access the menu almost immediately after power up (when the company's logo is displayed). For example, hitting the Escape key or left-clicking the mouse will produce the boot menu on several computer brands.
(4) Using
arrow or tab key to scroll, select CD as the choice for booting.
On some older computers, you may still have a problem. See "If all else
fails..." below.
Simple Booting for Apple Computers (Intel only)
(1) Place
our live-CD in your CD/DVD drive then shut down your computer.
(2) Restart (power up) and hold down the "c" key.
(3) Press the Return/Enter key at the Supercomputing Simplified splash
screen and watch the CD boot.
If all else fails (and you have an x86-compatible processor)...
(1a) You can return the disk for a refund. Contact us. Or
(1b) You need to change the boot priority in the BIOS.
WARNING: If you choose to change the BIOS, YOU MUST BE EXTREMELY CAREFUL. Improper changes to the BIOS will prevent your computer from working! You must ONLY change the boot priority!
Place
our live-CD in your CD/DVD drive then shut down your computer.
(2) Restart (power up) and PAY ATTENTION.
(3) The computer will display an instruction about entering something
similar to the following "BIOS", "Setup", "System Settings" or some
combination thereof (referred to as the BIOS here). About 90% of
computers will ask users to press the "F8" or the "delete" key to enter
the BIOS. Tapping the required key from the time the computer starts up
until BIOS opens is the most reliable way to open the BIOS.
If you do not see any instructions, many computers display
the instruction about entering the BIOS for just a few seconds, so look
more than once at the screens that quickly appear just after start-up.
(4) Once in the BIOS,
read your computer's instructions carefully. Follow
your computer's instructions, our description here can only tell you
typical
keystrokes which may or may not differ from the specifics of your
machine. There will be several screens of settings and
options. Find the "boot order" or "boot device priority" or
something similar. This usually appears under "Advanced ...
Settings". The CD ROM (DVD ROMs count as CD ROMs if you are a BIOS)
MUST have a priority above the hard drive. Make
the CDROM the FIRST boot device. Navigation and changing settings is
accomplished on 90% of BIOS with the arrow keys, "tab" and "enter".
(5) After changing the CDROM to become the FIRST / PRIMARY boot device,
save
the settings and exit the BIOS. Saving and exiting is usually
a menu option or the "F10" key (read your BIOS instructions carefully
and use the appropriate keystrokes for your particular BIOS).
Your computer will
automatically restart upon exiting the BIOS.
Returning to the original operating system
If you have a boot menu, just restart your computer, and it should look to the hard drive and ignore the CD (if the live-CD is still in the drive). However, as a general procedure we recommend removing the live-CD before power goes off at the end of a proper linux shut down.
Proper
linux shutdown procedure: 
(1) Find
the red colored Log Out/Shutdown button. It will appear in the
corner of the toolbar and/or at the bottom of the K applications pop-up
menu. Click on this red icon.
(2) A window for ending the Knoppix session will then appear. Choose
either 'Turn Off' or 'Restart the Computer'.
(3) The live-CD shutdown procedure will begin by switching to a
colorized text screen. The system will report its progress and
activities to the screen.
(4)
Eventually a line prompting you to remove the CD appears at the bottom
of the screen; wait a few seconds, some systems will automatically
eject the CD, or you can remove the CD manually if you have such a
button on your keyboard. Remove the CD from the open
tray/door; close
the door; then and hit Return. Your computer should reboot with its
normal operating system.
* If you have managed to use the live-CD with an external CD/DVD ROM drive, there will be NO automatic disk ejection or door opening; that is, when the screen instructs you to remove the CD from the tray, this will not be immediately possible. In such a case, either (1) unplug your CD/DVD ROM drive and restart, then once in the normal operating system extract the live-CD by plugging the external drive back into your computer and clicking for drive eject. Or (2) you can use an unwound paper clip to open the drive mechanically and then remove the live-CD, here's how: In the circular, paper-clip-sized hole provided in the front of the external drive, use the unwound bit of paper-clip wire to push in on the internal button.
