Ok, so here's a two part question:

1. Just say something has gone terribly wrong and I cannot boot into Windows.
Some corrupt Windows file - I’m thinking important things like winload.exe and some vital dll's - or maybe something has gone wrong in the registry.

How do I do a repair install to fix the problem without deleting all of my programs, current registry etc?
I know in XP you could just boot off the disk and do a repair install, but I can't seem to find a similar function with 7.

2. Here is a situation that has led me to be in the above situation many times. You have a perfectly operating Windows 7 installation (and assume this would apply to Vista too) and you go and do something like: change a motherboard, move the HDD from one computer to another... or in some way or another CHANGE THE STORAGE CONTROLLER that the HDD has to boot from.

This results in a BSOD on boot. I would assume this is because the installation doesn’t have the driver for the controller, and if it does - it isn’t installed, and set to boot from that controller (bad wording there, but I am guessing that there is some way that the windows install is set to boot from only the specified storage controller/driver)

Again, in XP, I would just do a repair install booting to CD with the correct storage controller driver. This was tedious, but the only way I knew of to get the HDD booting again.

So, as I cannot seem to find a way of repair installing with 7/Vista (and even if I did find a way, I hope there is some easier thing I can do), what can I do to stop this problem from occurring when the storage controller is changed? Can I pre-install the driver? How do I set it to use that driver to boot? (again, assuming something like this happens)

Sorry for the long winded question(s), I hope you guys can help me out! :)
