I've inserted an HD from a Dell with Windows 7 already installed, how do I get my Mac Pro to boot using that HD without having to reinstall Windows?

Hold down option while booting, then select your Windows install from the EFI display.

Pretty sure you'd need to use Boot Camp to install appropriate drivers first, no? – ghoppe Aug 22 '10 at 20:38
What I -think- I know about this is that those drivers should have no impact on being able to boot the system in the first place. Boot Camp is really just the name Apple gives to the utilities that can -help- install Windows by repartitioning your drive, and the drivers that allow Windows to fully support your hardware. In other words, I'm pretty sure you can just boot cold and then install the drivers later to get full support of the I/O up to speed. – NReilingh Aug 23 '10 at 2:47
