We have had problems like this during beta testing of Windows. Say, for
example, a problem occurs and you cannot access your current windows
environment. A quick solution is to do a side by side install. In other
words install the operating system to another partition solely for the
purpose of gaining access to important data that you cannot access on the
main partition because you are unable to boot to that copy of windows. Fine!
However, Microsoft say different. Do a side by side install, then recover
any data you need. After that remove the second install (or both installs)
and just install one copy.
'Open book concept' or not you 'cannot' run two instances (even on VM
software) of the same operating system without the appropriate licence for
'each' If you have a copy of Vista on drive C: and you want to put another
copy on drive D: (or on a VM) the you 'must' buy another licence. Every
single copy of the operating system on your PC needs a licence.
