“Windows Setup experienced an unexpected error. To install Windows, restart the installation.”

While upgrading Windows 2003 with Windows 2008 following error is coming and setup is terminating:

“Windows Setup experienced an unexpected error. To install Windows, restart the installation.”

This was coming on my Dell PowerVault 745N and I found that the System volume (partition on which Windows was installed) is a mirrored dynamic volume and when I break it by right clicking on the system volume displayed in Disk Management under Administrative Tools=>Computer management, up gradation process started. After upgrading the mirror can be re established from the same Disk Management.
