I keep a copy of the Windows 2000 CD-ROM on my disk, and use it to install or upgrade Windows 2000. To prevent an install, or SFC, from prompting for the CD-ROM:
1. Copy the Windows 2000 CD-ROM to a folder on your disk drive. Example: C:\W2K. You can slipstream the latest service pack if you wish.
2. Use Regedt32 to navigate to:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Setup.
3. Double-click the Installation Sources Value Name, a REG_MULTI_SZ data type, and set the data value to the I386 folder on your disk drive. You can add additional lines for 3rd party drivers. Example: D:\W2K\I386
4. Double-click the SourcePath Value Name, a REG_SZ data type, and set the data value to the folder on your disk, from step 1. Example: D:\W2K.
