How to Return to MS-DOS 5.0 If Uninstall Fails
If you have not installed DoubleSpace, carry out the procedure on page
179 of the "Microsoft MS-DOS 6 User's Guide" to restore MS-DOS 5.0. If
this procedure does not work, or if you have installed DoubleSpace,
carry out the following procedure:
NOTE: Use this procedure only if you are restoring MS-DOS 5.0. If your
previous version of MS-DOS is earlier than 5.0, do not use this
• To remove DoubleSpace and save your files, carry out the procedure
in section 7.6 of the README.TXT file, which is in the directory that
contains your MS-DOS files (usually C:\DOS).
• Use the SETVER command to specify to the Setup program that your
computer uses MS-DOS 5.0. For example, type the following at the
MS-DOS command prompt:
• Remove the read-only attribute from the COMMAND.COM file on drive C
by typing attrib c:\command.com -r at

How to Return to a Version of MS-DOS Earlier Than MS-DOS 5.0
To return to a version of MS-DOS earlier than MS-DOS 5.0, carry out
the following procedure:
• If you have repartitioned your hard disk drive, you may be unable
to see your partitions when you start your computer with a previous
version of MS-DOS. If this is the case, you must do the following:
• Back up your data.
• Repartition your drive(s).
• Format your drives. Be sure to use the /S parameter when you format
• Restore your data.
• If you did not repartition your drive(s) after you installed MS-DOS
6.0, restart your computer with a system disk from your previous
version of MS-DOS in drive A.
• If you can see all your partitions (using the DIR command), use the
SYS command to transfer the MS-DOS system files to drive C. For
example, type sys a: C: at the MS-DOS
command prompt and then press ENTER.
• If the SYS command fails because it cannot find room on drive C,
you can do the following:
• Use a third-party utility (such as Norton Utilities by Symantec) to
make drive C bootable.
• Use the FORMAT command with the /S parameter to reformat drive C and
transfer the MS-DOS system files. For example, type format c: /s at the MS-DOS command prompt and then
WARNING: Using the FORMAT command erases all the files on drive C. If
you back up your hard disk prior to formatting it, be sure to use a
backup utility that is compatible with your earlier version of MS-DOS.
Copy all the MS-DOS program files from the original MS-DOS disks to
the directory that contains your MS-DOS files (usually \DOS).
