1. Start your computer from the CD-ROM or the Setup Boot disks.

2. Perform a Manual repair.

3. Select [X] Inspect Boot Sector only.

Windows NT

2. When prompted for Setup options, choose R for Repair. 

3. Select only the Inspect Boot Sector option.

5. If you DO NOT have an ERD, press ESC to allow Setup to detect your installation.

After the repair

1. Start your Windows operating system.
