Change master boot drive?

Hi, all!! Current machine has three physical SATA drives: one boot (originally Vista, then installed Win7), second drive with the Win7 I use as my "main" boot volume, and a third for just data. Basically, I want to remove the old drive (C:, MBR, Vista & Win7 installed) and use the second "main" Win7 drive to act as the primary boot device.

Is there a quick way to do this? With Win7 and SATA drives I'm unsure where to go from here...

Thanks!

Found the solution. Booted ERD, opted to repair the volume in question, Command Prompt, and entered:

>> bcdboot c:\windows /s c:

Even tho the only volumes mounted at the time were Z: and T:, using the C: identifier worked perfectly. Booted, drive I wanted to be the master came up perfectly fine, and drive mapping in Windows was still Z:.

No muss, no fuss.
