After you use the System Restore tool to restore a restore point to revert the computer to a previous state, the computer may not restart.
This issue can occur if the restore point does not restore your computer correctly and the hard disk uses drive overlay software.
To resolve this issue, contact the manufacturer of the drive overlay software to determine how to restart the computer from a Startup disk while using the drive overlay software.
The Windows Millennium Edition (Me) Startup disk contains a program that is designed to automatically undo an unsuccessful restore point in most circumstances, allowing the computer to restart successfully as though the unsuccessful restore did not occur.
When the issue that is described in this article occurs, the Windows Me startup (splash) screen is not displayed. Restarting the computer from the Windows Me Startup disk and using the dir command on drive C does not show the expected files and folders. In addition, when you examine the computer's partitions by using option 4 (Display Partition Information) in the Fdisk tool, the drive C partition is is displayed as using "Unknown file system."
