When you try to upgrade a computer to Windows Vista, you receive the following error message:
You experience this problem even if you have sufficient hard disk space to install Windows Vista.
This problem occurs if the active partition on the computer is a hidden partition. To install Windows Vista, the Windows Vista Setup program must put certain files on the active partition. However, if the active partition is hidden, the Windows Vista Setup program cannot locate this partition.
To resolve this problem, set the active partition to a partition type that is not hidden. For example, set the active partition to type 0x7. To do this, follow these steps.
