- You have a computer that is running Windows 7.
- The computer has a volume that is larger than the system drive on which Windows 7 is installed.
- The volume has no drive letter assigned.
- You try to upgrade the computer to Windows 8.
You may configure a computer in this manner for various reasons. For example, you have a dual-boot system, and you do not want to assign a drive letter to the second system drive. Or, the computer manufacturer configures this volume to store recovery data.
Note This issue does not occur when you perform a clean installation of Windows 8.
When this issue occurs, the following information is logged in the Setupact.log file in the C:\windows\panther directory:
