renaming drive C to D where Window 7 is installed on D Drive

[glenndibler]

I have a dual boot computer that had a corrupt Win 7 installation on c and a good win 7 running on D drive. I deleted the corrupt win 7 on the C Drive from the dual boot startup and renamed the Windows 7 Directory on the C Drive to window.sold and used windows cleanup to delete, and Windows 7 is still running good with it starting on the D Drive.
There is still 1 directory on the C drive (Program Files) that the system will not allow me to delete, and about 10 or so files left over from the corrupt windows 7 install ,
My question is can I now rename the D Drive to C and then format the newly renamed D Drive so as to create storage and still have a functioning computer.

Note: There are 2 individual drives on the computer.

STOP

Let's verify:
You have 2 individual drives
With an OS on each
One of them is badly corrupt and does not run

Correct so far?

Ignore 'drive letters' for now. With a dual boot system, they change.

Power down
The drive you wish to keep with the functioning OS...leave that in and disconnect ALL other drives.
Power up
Does it boot correctly?


We cannot proceed with what to do until we verify this functionality.

Is there any option other than remove the current c: drive. Yes there are 2 individual drives. The D: Drive contains the correct functioning windows 7 OS. The C: Drive contains only the program files directory and several files in the root directory. All other directories have been deleted.

As said...disregard drive letters, for now.
Do you want a functioning system, or do you just want to forge ahead with blindly swapping drive letters? And possibly make the whole thing unusable/unbootable.

My first post was to establish a baseline that we can move from.
Does it boot with the one and only drive connected?

This may have already borked things up, but lets see what we're working with.
