I have one HDD, partitioned into three partitions. One contains XP 32, the other contains Vista Ultimate 32, and one final partition I made for Windows 7.
I already installed Windows 7 onto the third partition, but want to import all my installation data and registry, changes, etc, that I made in Vista, into Windows 7.
The way I see it, you have two options. You can use Easy Transfer Wizard to copy the documents and and settings associated with your user account, from Vista to 7. However, this will NOT migrate any of your applications, you'll have to install those manually.
Option 2 is to do an in-place upgrade from Vista to 7, provided that you have Windows 7 Ultimate 32. That way you will maintain all your apps and settings. It probably won't be as snappy as a clean install, though.
You see, I've installed Windows 7 and it messed up my Vista install.
Vista boots up insanely slow, a few programs stopped working properly, and I cannot restore to a previous time (an unspecified error has prevented system restore from completing, or whatever).
So I figured I'd just import all my installations into Windows 7, unless I can figure out how to fix Vista.
You won't be able to move application installs into Windows 7 unless you do an in-place upgrade of Vista to 7. But since you have already said your Vista install is acting strange, I'll assume that option is off the list...
