DOCUMENT:Q104988 25-NOV-1999 [msdos] TITLE :How to Recover from a Failed MS-DOS 6.2 Step-Up Installation PRODUCT :Microsoft Disk Operating System PROD/VER:MS-DOS:6.2 OPER/SYS: KEYWORDS: ====================================================================== ------------------------------------------------------------------------------- The information in this article applies to: - Microsoft MS-DOS operating system version 6.2 ------------------------------------------------------------------------------- SUMMARY ======= 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.
