Heh that part I don't know about, not sure if the 100meg or the other one is suposed to be active. But if it boots then that's probably fine.
Are you by some miracle able to delete the old Vista partion now? I'd bet odds no but stranger things have happened :)
The 100mb System Reserved partition is what is booting Win7, as shown in Disk Management by the "System Active" status.
It gives you the "Repair My Computer" console available on Advanced Boot Tools menu accessed by tapping F8 at bootup, which is a convenience since otherwise you'd have to use Repair CD or your Install DVD repair console.
We only suggested removing the Active flag from your F drive so that System can't be derailed to it if you should need to run Startup Repair.
If you have not resolved deleting Vista OS files, then consider moving the data off the partition and formatting it logical for data which also precludes it from being marked Active by accident, or follow SIW2's link to Paragon Rescue CD to delete the files you want gone. It is also the best tool for file recovery if your Win7 ever fails to start.
Apparently the only way to remove the old Vista Windows folders is to use a non-Windows OS to do it. It's surprising MS doesn't say this in plain language in one of their KB articles.
So far the easiest way I've found to get to a non-Windows OS is to boot the Vista CD and hit Shift-F10 to get to a command prompt. That's probably what I'll do.
