JSI Tip 4122. You installed a clean copy of Windows 2000 but your system now dual-boots between the existing and clean install?


If you attempted to reinstall Windows 2000 by performing a clean install from the existing installion, you may find that your computer now dual-boots between the original and clean installation.

This is most likely to happen if you upgraded from W9x. The upgraded installation was located in the \Windows folder and the clean install defaulted to the \Winnt folder.

To remove the original installation:

1. Open a CMD prompt and type attrib -r -s -h c:\boot.ini

2. Use Notepad to open the C:\boot.ini file. It will look similar to:

\[boot loader\]
timeout=30
default=multi(0)disk(0)rdisk(0)partition(1)\WINNT
\[operating systems\]
multi(0)disk(0)rdisk(0)partition(1)\WINNT="Microsoft Windows 2000 Professional" /fastdetect
multi(0)disk(0)rdisk(0)partition(1)\Windows="Microsoft Windows 2000 Professional" /fastdetect
3. Make sure that the Default= line ends in \WINNT.

4. Set the timeout= to 0 or a low number of seconds.

5. Remove the line that contains the \Windows folder.

6. Save the C:\boot.ini file. It should look similar to:

\[boot loader\]
timeout=7
default=multi(0)disk(0)rdisk(0)partition(1)\WINNT
\[operating systems\]
multi(0)disk(0)rdisk(0)partition(1)\WINNT="Microsoft Windows 2000 Professional" /fastdetect
7. If you have any personal files in the \Windows folder, relocate them.

8. Delete the \Windows folder.
