Thanks for the I advice. I have managed to install the Windows 2000 Professional on my D drive and I have Windows 98 on my C drive. It works fine on my D drive.<br><br>There is a minor problem. Since the first installation of my Windows 2000 was corrupted, I was asked to run setup again. I did as I was told and the installation is a success. However, when I boot up my computer, The Windows 2000 boot loader showed me 3 options. The first and second options are to load Windows 2000 and the third oprion is to load Windows 98. <br><br>The second option is from the earlier installation of Windows 2000 which has corrupted. How could I removed away this option?
