overlay install

About this tag
The overlay install tag on WindowsForum.com covers discussions about performing a Windows 7 overlay installation, where a newer version of Windows is installed over an existing installation without formatting the drive. In one thread, a user attempts an overlay install from a Windows 7 Ultimate DVD onto a hard drive containing an expired beta of Windows 7, encountering a 'Cannot Boot From CD, Code 5' error.

This tag is relevant for users seeking to upgrade or repair Windows installations using an overlay method.
