Solution

you may need to specify diskette
capacity. For example, to format a
1.44-MB diskette, type the following
command at the MS-DOS prompt:
FORMAT A: /F:1440
In Windows 2000 and Windows
XP, right-click Start, click Explore,
and select a drive. Select File >
Properties > Tools. Under
Error-checking, click Check
Now.
Format the diskette.
Check the type of drive that you
are using and use the correct
diskette type.
Check the drive letter in the path
statement.
Replace the diskette with a new one.
When drive activity stops, remove
the diskette and press the
Spacebar. The computer should
start up.
Restart the computer by pressing the
power button.
Replace with a bootable diskette.
