Windows 7 showing two installed locations!

Sorry if this is a re-post but I tried searching for this problem but haven't found one exactly like this.

I recently deleted, reformatted, and installed windows 7 ultimate on my hard drive. Everything installed great and seems to run okay but I noticed there are two copies showing up in "My Computer" and Drive D: Local Disk is an exact copy of my old systems windows and program files. I can still run the programs installed on this disk. What is really odd is that my computer is showing the hard drive which has both installs of windows at 1000GB, when in reality it is only a 500GB drive. This old windows copy seems to be living on a disk that doesn't exist.

I suppose I could have reformatting wrong but I have done this many times. I deleted the old partition and re-formatted. I have no idea how this information is even still on the drive.

I also noticed that as my C drive (new install on win7) begins to be filled up with installing software the D drive is depleting. As if they are sharing the 500GB drive and windows somehow is confused and showing them separately - doubling up the hard drive space that really isnt there.

If this makes any sense and you think you can help it would be much appreciated! I figure I'm going to have to re-install windows again but if I somehow missed something I don't want to run into a system with 3 installs of windows 7. Thanks!

Here is the screen shot. Disk C and Disk E should be sharing a 500 GB hard drive. Im not sure why it shows a Disk 0 with 931GB of space. Disk D is the old installation of windows.

You left the old Win7 on the HD instead of installing over it. It is shown in the screenshot as D, with it's old 100mb boot partition immediately to its left and now abandoned.

This would be okay - we could just have you delete D and the small boot partition and resize C into its space - except that you installed to a Logical data partition which cannot host boot files, so it placed them on the old Win7 partition D.

Your choices are to start over by booting the installer to use Custom drive options to delete all partitions, create and format New one(s) as you wish as shown in Step 6-7 in Clean Install Windows 7.

Or you can boot free Partition Wizard bootable CD, righclick on C to Modify>Set to Primary, click OK. Then rightclick C again to Modify>Set to Active, OK. Then click on the HD to highlight it and from Disk tab select Rebuild MBR, click OK, Apply all steps.

If Win7 doesn't start boot into WIn7 installer to run Startup Repair - Run up to 3 Separate Times until Win7 starts and holds the System boot files.

Now that you know Win7 will boot from C partition, you can boot again into PW CD, rightclick D and the 100mb partitions to delete, click OK after each, then rightclick C to Resize, drag left border all the way to the left to take up the space you deleted, OK, apply all steps.

Thanks for the help.. I did delete the disk though and that is what I don't understand. But I think I left the 100mb boot partition there because it would not let me delete it and I was rushing to get my comp back up and running to finish some maya 3d homework. Lol.

Which option do you think is better? To reinstall windows correctly? Or the second option?

I would prefer to have a clean install so I'm guessing starting over is the best option for that, right?

Cool.. Haven't grown attached to it, lol. It makes me feel dirty. I've done it many times but I wasn't paying enough attention because I was going madly insane and rushed it.

Thanks for the help!

If you study the steps and prepare, ask back any questions, make all the preparations, then do it in slow motion using only the methods and tools to get and maintain a perfect install, it will live on if you want for the life of the OS in a backup image.

Yeah, I'm already looking into the links you posted. Really like this ninite installer! I might backup this time, might as well since I still have a copy of the old windows install.
