Since you have Entreprise, you cannot upgrade to Windows 8.1 like that, true. Also, it's really, really rare that BSOD issues will be solved by running SFC or DISM. If this is the issue you want to address, I would create a new thread in the BSOD section instead and get assistance there. Once that issue have been solved, you could comeback here and we could investigate why DISM is throwing an error code even though no corruption is actually detected :)
