I have a Windows 7 machine with two internal physical drives. Some how I made drive D the boot drive and drive C the system drive. Both are active. Both are physical. I need to make the C: drive both system and Boot. How can I move boot from D to C?
 
you cannot change these drive letters.

you will need to format and reinstall (with the 2nd drive disconnected)

this is a common occurance when people have a USB internal card reader. if you dont disconnect it proir to install you will end up with a F: as your windows drive.
 


So, to make sure I understand correctly, the C drive contains Windows, but it boots from D?

If so, this is a simple fix. Grab your Windows DVD, and stick it in.

Shut down your computer, and then unplug the D drive.

Startup the computer and boot from the DVD. Run startup repair and it should automatically create the necessary files on C in order to boot from that drive.

After you've booted from C, shut down and plug D back in.
