Threads are not closed here as many live on for years in Google searches and thus require being kept current. This is also the top tech forums on the web so accuracy is going to be dealt with at all times.
Are you sure it wasn't a Custom and not Upgrade install? Choosing the Upgrade track will only in-place Upgrade the presently booted OS.
Almost all of the known workarounds for Win7 install were either developed here or are at least known to us. There is not one I've ever seen to allow in-place Upgrade to another OS besides the one booted into.
Anyone else?
