If MS-DOS 6.2 Step-Up Setup is interrupted before the update is finished, restart your computer with your Uninstall disk in drive A, uninstall MS-DOS 6.2, and then run Step-Up Setup again.

If your Uninstall disk is unavailable for some reason, you can use the following procedure to work around this problem:

  1. Copy all files from the C:\OLD_DOS.1 directory to your original MS-DOS directory (typically C:\DOS).
  2. Start (boot) your computer from an MS-DOS 6.0 floppy disk.
  3. Use the SYS program to transfer the MS-DOS 6.0 system files to drive C (or the host drive for C if C is compressed).
  4. Run MS-DOS 6.2 Step-Up Setup again.

If Step-Up cannot run because it does not recognize your MS-DOS 6.0 files, you may have to install MS-DOS 6.0 before you run Step-Up again. For more information, see section 4 of the MS-DOS 6.2 Step-Up README.NOW file.
