If you must boot from the CD, you need to set your BIOS to "boot from CD" first. Once you do this, your PC will boot from the CD. Make sure the bootable CD is in the drive & reboot. If you must boot from a floppy, set the BIOS to "boot from floppy A:". Make sure there is a bootable floppy in the drive & reboot. If you choose the desired boot source and properly save the new settings into your BIOS, upon rebooting your PC will boot from the choice you saved, be it A, C (or HDD 0/1/2/3/4), CDROM. If the BIOS allows disabling the other boot options, make sure you do so & enable but the one you desire only. Or it may say something like this: IDE Primary Master IDE Primary Slave IDE Secondary Master IDE Secondary Slave In which case your POST screen (what you see as the PC boots) will indicate which device is identified as your CDROM. If the screen runs by too fast hit the Pause/Break key to stop it. Then press any key to continue the POST.(Power On Self Test) Go here: http://www.buildeasypc.com/sw/bios_setup.htm and look at some basic instructions for an Award brand BIOS with pictures. You need to look in "Advanced BIOS Features". That is all it entails, Donny. I can't imagine why you wouldn't be able to do this if you say the PC reads the CDs & the floppies properly and that you have accessed the BIOS and made the desired changes and saved them before exiting the BIOS interface.<SHRUG> Don't you have any documentation/manuals that accompanied your PC when you bought it? Get it out and read your PC's instructions on accomplishing this - "Changing the boot order" or "Choosing first boot device", or something in that order. Got a friend who can help you with this? Call him/her and seek his/her assistance. armando Some days you're the dog, some days you're the hydrant.
