I put my windows 2000 cd to repair. I hear it run and then it stops?microsoft net framework

Open the drive with the CD in it using Explore.

Then look for a file in the root directory called AUTORUN.

Since you already have 2000 installed the menu will ask whether you want to Repair or Replace the current installation.

You can take it from there.
