Recently I ran into several vagrant issue on windows host.
List down my environment for your refference:
OS: windows 7
One of the issue is that for different VM provisioned from same box, their disks are all stored in a folder with box name prefixed instead of folder name that Vagrantfile placed.
See this ticket which has a graph showing what's happening.
And the root cause is somehow related to windows backslash path.

Just replace the file under following path on your windows host with the fix:

After doing so, it all works well now.
