You won't be able to format your C: drive because that is where the Windows boot files are. You need to use the C: drive and get rid of the D: drive. Why do you want to use D: rather than the more usual C:?

A common confusion. Windows will always call the partition that it is on C drive. Always. Each installation of Windows (all versions) will call the partition it is on C drive and the other D drive so it is easy to think that you want to remove the wrong one. If the partitions are not exactly the same size you can see this in Computer and in Disk Manager by the size of the drive showing. If you are in the newest installation of Windows 7 then the older one is D drive or another letter, when you are in the old installation of Windows then the new installation will be D drive or another letter. To remove the old installation you need to be in the new one and format or delete (better) the 'other' drive (non-C drive) from Disk Manager. If you deleted the drive then you create a new drive and format it or you can extend your current C drive to use it all.

You have to be a little bit crazy to keep you from going insane.

I'm not sure that is entirely correct. The MBR is pointing to a partition as the active partition that contains the boot record. If you format that drive the system will no longer boot because there will be no boot sector. At the very least a repair inatall will be needed.

I haven't tested with Windows 7, but I have certainly had 2000 and XP installations where the system disk was not C:. Well written programs and batch files will not rely upon the system files being on C: but will get the location from an environment variable (%SYSTEMDRIVE%).
