It was an old desktop owned by a late neighbour. When I turned it on it would give an error message:

Diskette drive 0 seek failure
Press F1 to continue, F2 to enter SETUP

F1 will boot into Windows and F2 goes into the BIOS setup.

A little research online and found out the problem was more likely a floppy disk error. This computer has no floppy drive. So I went into the BIOS to try and disable it.

So I pressed F2.

On the first screen I used the arrow keys to move to the line Standard CMOS Features and pressed Enter.

ON the next screen I used the arrow keys to scroll down and highlight the Drive A [1.44M, 3.5 in.] and pressed Enter.

Then a small window opened giving me the option to disable the drive. I used the arrow key to move the little square dot up from 1.44M, 3.5 in. To None then pressed Enter.

Then I clicked on F10. I got the message SAVE to CMOS and EXIT (Y/N)? Y

Type Y for yes and N for No. The Y was already there so I just pressed Enter.

This rebooted the computer automatically and since it wasn't looking for a floppy disk that wasn't there I didn't get the error message.
