Vista - Change drive letter 4 a partition that Vista marks as system wrong

I'm trying to change a drive letter to a partition in Vista using Disk
Management. I don't have an OS installed on this partition (nither Vista nor
XP), but Vista insists its a system partition (in addition to C: which has
Vista on it as usual).

How can I convince Vista that I have no system on this partition?

If it helps - I did have XP installed before I installed Vista on a third,
unrelate partition, that I already deleted (deleted the whole partition with
XP on it).

The system partition has your boot files on it. It is the first hard drive
in boot priority and the active partition. You would have to make your
Vista drive match these criteria and then run the start-up repair. That
would make it so you could change your drive letter.

- Both C: (where my Vista is) and the troublesome partition are marked with
"System" and "Active" in the Disk Management.
- I have no boot files on the troublesome partition (yes, I see hidden files
as well).
- What is the "start-up repair"? Is it still relevant after the two points
above?

You don't say whether the two partitions are on the same or different hard
drives. Are you using, or have you installed a 3rd party (Linux, System
Commander, etc) boot manager at some point. There are a number of ways you
could approach the problem, but the safest would be to copy anything you
have on the partition off, delete and recreate the partition and copy your
data back. Other options would would include using WinRE to see if fixing
the MBR or Boot records (on the partition you want to change) would help,
seeing if you can change the drive letter from WinRE and you could change
the letter that mount manager has in the registry or delete the entry and
let mount manager remount it on the next boot. While registry entries are
somewhat dangerous, if system restore is working and you do a restore point
beforehand, you can run system restore from the DVD in a worst case to
restore the prior registry. The active partition on Disk 0 should be the
only one Vista would mark as system under normal circumstances. Make sure
that is where your boot files are in any case. If you want to post back, it
would be helpful if you would supply the information for all your partitions
on the hard drives from the top panel and which disk and order they are on
from the lower panel. Good luck.
