When you use the System Restore feature in Windows Vista or in Microsoft Windows Server Code Name “Longhorn,” you receive the following message:

No Restore Points have been created on your computer’s system disk.

Additionally, only the most recent backup files from Windows Vista Complete PC Backup are available. Earlier versions of the backup files are unavailable. You experience this problem if you are running Windows Vista or Windows Server “Longhorn” on a computer that is also configured to run an earlier Windows operating system.

Note: This configuration is known as a dual-boot configuration.
