Boot Problems
The message "Operating System Not Found", or "Non-System disk or disk error" appears during
boot-up.
This message implies that your computer cannot find any operating system on the first boot media. (You may
refer to the
BIOS Setup chapter
for more information on the boot sequence).
Most of the time, this happens because a non-bootable diskette is inserted in the floppy disk drive, and the
computer unsuccessfully tries to boot on this diskette. Remove the floppy disk (you do NOT need to insert a
bootable floppy disk instead) and follow the on-screen instructions.
Why can't I boot from the floppy disk drive?
To boot from the floppy disk drive, be sure that you have a floppy disk in the drive containing operating
system files (also known as bootable floppy or system floppy). Be sure to check the boot sequence in the
BIOS Setup chapter.
See your operating system documentation for information on how to create a system floppy.
What is the difference between a warm boot and a cold boot?
A warm boot restarts the system while system power is on. This process resets the software by clearing the
volatile system memory and reloading the operating system.
A cold boot is a system start with power off. This process resets and checks the hardware, and reloads the
operating system.
Why does my computer automatically boot up when I receive a phone call?
Make sure your BIOS parameters are correctly set up. (You may refer to the
BIOS Setup chapter
for more
information on the wake up events).
