Disk I/O error as computer starts.
Question:
Disk I/O error as computer starts.
Answer:
A disk I/O error occurs any time the computer is unable to read a
diskette, disc, or other disk in the computer. Below are different
recommendations to try before assuming the diskette, disc, or other
disk is bad.
Floppy diskette or CD / DVD
disc in the computer
If you're attempting to boot the computer from a floppy
diskette, CD, or other disc follow the below recommendations. If
you're not attempting to boot from a diskette or disc make sure
no floppy diskette or CD is in the computer. It's possible the
computer may be trying to boot from a non-bootable disk, which
is causing this error.
- Remove the floppy diskette or CD from the computer and
put it back in and press any key to continue.
- Try rebooting the computer.
- Recreate the bootable diskette / CD you're attempting to
boot from. It's possible it's bad and the computer is unable
to use it. If this is a CD or DVD try
cleaning it.
- Try booting the diskette or disc in a different
computer. If that computer is able to boot without the error
it's likely you're encountering an issue with your drive.
See document CH000277 for basic
floppy drive troubleshooting.
No diskette or CD disc in the
computer
If you have no diskette or CD in the computer and are getting
the Disk I/O error as the computer is starting this is referring
to your hard disk drive. Unfortunately this is often an
indication of a hard disk drive failure, follow the
recommendations on document CH000454
for steps that can be done to check for hard drive failure.
