I am having a problem installing Windows NT server. When I start up the computer using the installation disks, they are supposed to be copying files to the hard drive. But they don't. When the process gets through the 3rd disk, it says that it cannot install the operating system. Afterwards I check the hard drive and find that nothing was copied to it. I did the process again to see if the hard drive light was on. It came on and stayed on. It didn't flicker like it usually does. Also, it stayed lit even though I was changing the floppy disks.
