SYMPTOMS
When you try to install MS-DOS, Setup repeatedly asks for a disk that you already inserted in the floppy disk drive. Or, Setup displays the following message when you insert the Uninstall disk in drive A:

ERROR

This is not the correct disk.

Press ENTER to continue.



CAUSE
Setup may repeatedly ask for a disk for several reasons:
 * The disk is a copy of an original Upgrade disk, and the copy does not have the volume label of the original.
 * The disk you are using for the Uninstall procedure is incorrectly formatted.
 * The device driver that controls your floppy disk drive is not reporting that the drive door is closed after you insert a floppy disk.
 * Your system is infected with a virus.



If Setup Repeatedly Asks for an Upgrade Disk
If Setup repeatedly asks for an Upgrade disk, and the disk is a copy you made, do the following:  Insert the disk into drive A or B. Type the following

dir : /p

where is the drive you placed the disk in.  Check to make sure the volume label includes the word &quot;Disk,&quot; followed by six spaces and the correct number of the disk. For example, if the disk is Upgrade Disk 3, MS-DOS should display the following message:      Volume in drive A is DISK      3  If there are not exactly six spaces between &quot;Disk&quot; and the disk number, or if the disk number is incorrect, type

label :

where is the drive you placed the disk in. When MS-DOS prompts you for a volume label, type the correct label.</ol>

If Setup Repeatedly Asks for the Uninstall Disk
If Setup repeatedly asks for the Uninstall disk, use an unformatted disk. If using an unformatted disk does not work, do the following: <ol> Insert an unformatted disk into drive A.</li> Type the following:

format a: /s

MS-DOS formats the disk in drive A and transfers system files to it.</li>  Type the following, substituting a value listed in the following table for <x> and pressing ENTER at the end of each line

copy con a:config.sys

drivparm=/d:0 /f:<x> /c

where number assigned to the /d drivparm switch specifies the physical drive number. Drive A is 0, drive B is 1, drive C is 2, and so on.

The value of <x> depends on the type of disk drive you are using. The following table lists valid values: <pre class="fixed_text">     Drive size      Disk capacity      Values to use

5.25-inch      160K, 180K,         0 320K, 360K 5.25-inch      1.2 MB              1 3.5-inch       720K                2 3.5-inch       1.44 MB             7 3.5-inch       2.88 MB             9 </li> Press F6.</li> Restart your computer by pressing CTRL+ALT+DEL.</li> Insert MS-DOS 5.0 Upgrade Disk 1 into drive A.</li> Type the following:

a:setup

Follow the instructions on your screen.</li> If Setup still does not accept the Uninstall disk, run a virus-scanning program. If you have MS-DOS 6 or later Upgrade, you can run Microsoft Anti-Virus (MSAV.EXE). To do so, boot your computer from MS-DOS Setup Disk 1, insert Disk 3 of the 3.5-inch 1.44 megabyte (MB) disk set or Disk 4 of the 5.25-inch 1.2 MB disk set, and run MSAV. You receive an error message when MSAV attempts to write to the write-protected disk. You can choose Fail and ignore the message.</li> If the same disk is still repeatedly asked for, do the following:

<ol style="list-style-type: lower-alpha;"> Make a temporary directory on your hard disk drive.</li> Copy the installation disks to the temporary directory.</li> Change the MS-DOS command prompt to the temporary directory.</li> Run Setup from that directory.</li> When Setup is complete, delete the temporary directory.</li></ol> </li></ol>
