If you installed Windows 98 yourself, installing Windows 2000 shouldn't be to much hassle. After booting Windows 98, you just insert the Windows 2000 Installation CD and the installation should start up automatically. In case it doesn't start automatically you just execute the setup executable file found on the root of the CD. After the installation wizard has begun it's pretty easy. The installer should detect the currently installed Windows 98 and will give you the option to upgrade to Windows 2000. It also let's you run a compatibility check for the installed software to see if the applications you have installed on your system will run in Windows 2000 (you should select that when installing). After completing that the install system will restart you computer and begin the actual setup process which shouldn't be too hard to follow.
