If I'm understanding you correctly, it seems as if Win2K's Source Path is incorrect In other words, sounds like you installed from files on the hard drive, yet it still wants to see a CD. In any event, it's apparently a bug, which you can fix thusly. I just lifted this from the old Winmag.com website:
"Unfortunately, when you install Win2K from a local hard disk, the OS automatically records the source media as the first available CD-ROM drive letter instead of the local hard disk. So, when you add a new component, Win2K assumes the source media is the CD-ROM, and you have to enter the correct path manually. To work around the problem, you can change the default source media location by editing the source path value entry in these three Registry keys:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT CurrentVersion\Setup
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\WindowsNT CurrentVersion
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT CurrentVersion\Setup Installation Sources"
