NO BOOT DEVICE AVAILABLE — The computer cannot find the floppy disk
or hard drive.
• If the floppy drive is your boot device, ensure that a bootable floppy disk is in
the drive.
• If the hard drive is your boot device, ensure that the drive is installed, properly
seated, and partitioned as a boot device.
• Enter system setup and ensure that the boot sequence information is correct.
NO BOOT SECTOR ON HARD-DISK DRIVE — •The computer configuration
information in system setup might be incorrect. Enter system setup and
ensure that the computer configuration information for the hard drive is
correct.
• If the message continues to appear after you confirmed that the information
in system setup is correct, the operating system might have been corrupted.
Reinstall the operating system. See your operating system documentation for
reinstallation information.
NO TIMER TICK INTERRUPT — A chip on the system board might be
malfunctioning. Run the Dell Diagnostics.
NON-SYSTEM DISK OR DISK ERROR — The floppy disk in drive A or your
hard drive does not have a bootable operating system installed on it. Either
replace the floppy disk with one that has a bootable operating system, or remove
the floppy disk from drive A and restart the computer.
NOT A BOOT DISKETTE — The operating system is trying to boot to a floppy
disk that does not have a bootable operating system installed on it. Insert a
bootable floppy disk.
NOT ENOUGH MEMORY OR RESOURCES. CLOSE SOME PROGRAMS AND
TRY AGAIN — You have too many programs open. Close all windows and open
the program that you want to use. In some cases, you might have to restart your
computer to restore computer resources. If so, try running the program that you
want to use first.
