Windows Vista Switching hard drive to make Vista Primary OS

I have 2 hard drives. On my primary hard drive I have win 2000 and on my slave drive I have Vista 64. I want to delete win 2000, and then switch the cables on the hard drives. Making the slave, with vista, the Primary drive. And the primary, then becomes the slave drive. Can I do this and still boot to Vista, without any problems? I would like to avoid a re-install if possible.
Any help would greatly be appreciated.
Cheers,

 

Your system would not boot as the info required for booting is on your primary [Win2k] HDD.
