Computer May Not Boot After Canceling Setup During File Copy

The information in this article applies to:

• Microsoft Windows 95 OEM Service Release version 2.1

SYMPTOMS

If you cancel the setup of OEM Service Release version 2.1 (OSR2.1) over OEM Service Release 2 (OSR2) during the file copy stage, you receive a successful setup message and you are prompted to restart your computer. The next time you start your computer, you may receive real-mode error messages and a Windows Protection Error message, after which the computer stops responding (hangs). Subsequent reboots generate the same errors.

CAUSE

Some of the OSR2.1 files were not copied to the computer and Setup was not completed. Your computer contains a mixture of OSR2 and OSR2.1 files.

RESOLUTION

Run the OSR2.1 uninstall tool. This is a file named Rem.pss on the installation disk. To use the uninstall tool, follow these steps:

1. Restart your computer. When you see the "Starting Windows 95" message, press the F8 key, and then choose Safe Mode Command Prompt Only from the Startup menu.

2. Copy the Rem.pss file to the root directory of the boot drive as a file named Remusb.bat.

3. Type "remusb" (without quotation marks) to restore your original files.

4. Restart your computer normally. Use the Add/Remove Programs tool in Control Panel to remove the program named "WDM/USB Supplement."

   NOTE: This program may not be listed in the Add/Remove Programs tool depending on when Setup was canceled. If it is not listed, skip this step.

5. Delete the Remusb.bat file from the root directory of the boot drive.

MORE INFORMATION

There are several stages to Setup, and canceling Setup during most of them is harmless. The following list summarizes these stages:

• End User License Agreement - OK to cancel
• ScanDisk - Cancelling Setup during ScanDisk (or canceling ScanDisk itself) is OK
• Initial extraction from cabinet files - OK to cancel
• Actual file copy stage - problems will occur if you cancel Setup at this point.
