What is it you want to do?

Are both OS's booting via a Windows Boot Menu just after the BIOS post?

Or are you booting them via the BIOS as you said you had been doing, by tapping the BIOS Boot Menu Key at boot to trigger the chosen HD that way?

Since there are no boot files on E, it looks like it is booting off of C so you should have the Windows Boot Menu. Is this sufficient?

I also asked you if you had installed Ultimate from C so that it does not boot as C but E. If so you'll need to decide if you want Win7 on E since it is designed to always show as C when booted, if it is correctly installed from boot and not run from an OS.

Windows 7

What I am wanting to do is:-
When I choose to boot from my Seagate drive, I want that drive to be drive c: (which it currently does)
When I choose to boot from my Business drive, I want that drive to be drive c: (it currently is drive e:

Sorry about earlier confusion, I have EasyBCD installed and it prompts me for the boot drive at startup.

To the best of my knowledge, when I installed Windows Ultimate to my Business drive, I was booted into the Seagate drive, I then formatted my business drive e:, run setup from my cd/dvd drive and when prompted where to install my new operating system, I chose drive e: which was my newly formatted drive.

So if I now disconnect all hard drives except my business drive, and then reinstall my new Windows 7 Ultimate to that drive, and then reconnect my other drives, should that resolve the matter? I guess that I should also uninstall EasyBDC and it should then revert back to me having to tap the esc key to select my boot drive?

Gables - Boot the Win7 DVD, not the Seagate HD, to install Win7 correctly to your Business drive so that it shows as C - as Windows 7 always does when it is correctly installed from the booted installer.

Start over with all other HD's unplugged, follow these best practices to Clean Reinstall - Factory OEM Windows 7 which are the same for retail.

Once Win7 boots on its own power down to plug back in the Seagate, set preferred HD to boot first in BIOS setup, boot the other HD using one-time BIOS Boot Menu key as you did before.

If this is not optimal for your uses, install EasyBCD to the primary HD to add the other OS.

Take all the time you need to get it perfect.

Then after it's setup and running best according to the Best Pracctices in Clean Reinstall - Factory OEM Windows 7 save a Win7 backup image so you never have to reinstall again.

We're here if you need us.

Windows 7 x64

You BCDedit readout appears to be a normal, dual boot setup to Win 7 Ultimate as default and Win 7 Pro as the other choice.

So when you boot, you get the Boot Menu with Win 7 Pro (Not Default) listed first, so if you do not choose an OS, Win 7 Ultimate will boot. I would probably realign the choices so the default OS is listed first.

So, I suppose I am still a little confused by the "Going to E:" comments concerning your setup. But you are saying that Explorer shows Windows 7 Pro on the E: partition when you are booted to it. I think Gregrocker mentioned installs being messed up and the only time I have seen that is during a cloning operation.

I am sure gregrocker will straigten this out for you, but just for some info, I have attached an install with two hard drives. One with Window 7 and one with Windows 8. Each install was independent, so I can boot to either one by using the Boot Devices menu.

I have booted to each one in turn and show the Disk Management window and BCD Store for that respective boot. Good Luck with your situation.
