Windows 2000 Uninstallation


I have a C, D, and E drive and I had Windows 2000 installed on Drive C.  Recently I had a virus therefore I tried to reinstall Windows 2000.  I accidently chose to install a fresh copy of Windows 2000 and it installed it on the D Drive.  So at this time, I have a Windows 2000 that has viruses on drive C and a new copy of Windows 2000 on drive D.  

For some odd reasons, I just decided to go back on the Windows 2000 on drive C and just deleted the WINNT folder in drive D thinking that would uninstall the installation on drive D.  Obviously I found out that does not work and now when I boot up my computer I get to choose from two Operating System which is both Windows 2000 Professional.

My questions is, how do I let the computer know that I deleted the second installation of Windows 2000 that is on drive D ?

Thanks for helping

Editing the boot.ini File

To edit the boot.ini file in Notepad

Start Windows Explorer. Go to Tools | Folder Options | View. Make sure that Show Hidden Files and Folders is selected, and Hide File Extension for Known File Types is cleared.
Go to the root directory of the boot volume of your computer (on single-boot machines, usually C:\). Right-click on boot.ini. Select Properties, and remove the read-only attribute of this file. Click OK.
Double-click the file icon to start Notepad with boot.ini loaded.
If you are using an MS-DOSĀ® Command Prompt window, use the following commands instead of steps 1, 2, and 3:
cd \
attrib -s -h -r boot.ini
notepad boot.ini

Edit the file. (For a description of the boot.ini syntax, see Contents of the boot.ini File.)
Save the boot.ini file and quit Notepad. (You do not have to restore the original file attributes.)
Shut down the computer and restart Windows.
Remove the line that you don't want it will probably look like this
