When the BIOS Setup screen appears, use the commands described at the bottom of the screen to move the cursor to the "Boot" or "Boot Order" option on the menu. If these options are not shown, you may need to look for them in the other menus listed.
Once you have entered the boot menu, you will see a list of devices. The computer will try to boot from those devices in the order listed. If the internal hard disk is listed first, the CD drive containing BitFlare will not be accessed properly. Use the keys shown at the bottom of the screen to move the CD device to the top of the boot sequence list provided. This will not affect the performance of the computer in the future, because if no bootable CD is found, it will boot from the next device on the list (i.e., the hard drive).
When the boot order is correct, press the key indicated to "Save and Exit" the BIOS Setup utility. The PC should now restart and boot from the BitFlare CD if present in the CD drive.
