I Messed up

I was doing some work on my hard drives when I noticed I lost my internet connection. I unplugged everything and shutdown my pc. When I restarted I found I couldn't boot to C. I received an error message something like "Master Boot Record Missing" or something like that. I tried to repair C with the Win7 DVD but it could not find any installation of Windows.
I installed what I thought to be Win7 64bit but it turned out I grabbed the wrong disk and installed the 32bit version. Windows was installed to disc 0 which was actually D drive and prior to installation Windows formatted D into two partitions, one called "System Reserved" and the other a primary partition. After installing I copied the "autoexec.bat" and the configsys.ini to C, this being the 32bit not the 64bit(any difference?)
After restarting the computer I get the Windows Boot Manager Screen giving me two choices of OS, Windows 7 or Windows 7 (home premium) recovered. The Win 7 (home premium) recovered is the one I want. If I boot to the Windows DVD and try a repair, The Win 7 Home Premium version, Windows goes through the motions and after it's finished and you read all it has done to repair the OS, the bottom line is that it says that Windows has booted successfully. How do I get rid of the 32bit version that was installed on D and realizing that the autoexec.bat and the configsys.ini are incorrect, is there any way I can fix my OS?. Yea, I screwed up but not having access to the internet for that time period really posed a problem.

Please post back a screenshot of your full Disk Management drive map with listings showing all columns, using the Snipping Tool in Start Menu.

OK, i'm a dummy, how do you map a hard drive in Win7. I can only find answers on how to map a Network drive. Also, in the drop down box for drive letters C isn't even there

OK, here's the shots (I hope I got them right). C, needless to say is the primary drive, D is/ will be my work drive> D drive is where Win7 32bit was installed(dummy me) and that is where the 100mb SYSTEM RESERVE is located in partition 1,
E drive is my internal backup drive, I didn't include my cdrom which is F.

In Disk Management mark C Active, power down to unplug data cable from D, plug its data cable into C so that the OS HD is in preferred Disk0 slot. Partition - Mark as Active

Now boot the Win7 DVD Repair console or Repair CD to run Startup Repair up to 3 separate times with reboots until it writes the System boot files to C and Win7 starts. Startup Repair - Run 3 Separate Times

You can then plug D back in to Disk1 cable, boot if needed using one-time BIOS Boot Menu key, or use DiskPart Command-Line Options from Win7 Elevated Command Prompt to delete partitions using Delete Partition Override or wipe the HD using Clean.

In the future be aware that you never run an OS installer from an OS - always boot to install following these steps to get a perfect reinstall: Reinstalling Windows 7

I want to thank you guys for this info, but I'm just a little skeptical when it comes to windows, for some unknown reason Murphy's law comes into play more than not so lets just say that I follow your instructions and it just doesn't work. So now I'm going to have to re-install Win7, would I just re-install as usual or what? I'm not saying the instructions won't work, it's just that sometimes Windows just doesn't want to play fair.

Well, I have to admit everything worked out just fine and again thanks for the help. There is only one problem, instead of C being disk 0 it's disk 1. WHY? Is there any way I can change this or am I stuck with it. I give up. Take a look;
