Hi,
You cannot change drive letters assigned to designated system or boot
volumes without starting from scratch or until that volume no longer has one
of those designations. If Vista is installed to C: and you move the system
designation from I: to C:, you will then be able to to reletter that volume.
To do so, you would need to work from the recovery environment after
changing the active partition in disk management.
