Setup Prompts for CD-ROM When Installing to Removable Disk

ID: Q151388

The information in this article applies to:

Microsoft Windows NT Workstation version 4.0
Microsoft Windows NT Server version 4.0

SYMPTOMS

When you run Setup from a network drive to a removable hard disk, you may receive the following message during the GUI portion of Setup:


   Please insert the floppy disk labeled 'Windows NT Workstation
   CD-ROM' into drive C: and then click OK.

Setup continues once you click Browse, open the path to the temporary file location (for example, C:\$win_nt$.~ls,) and then click OK.

This may occur several times during Setup.

CAUSE

This behavior occurs because Setup cannot distinguish between a removable hard disk and a CD-ROM drive. As such, Setup expects a tag file to exist on the source drive. The tag file is not normally copied from the installation source. Additionally, if Setup is occurring over the network, then this file is not accessible.

RESOLUTION

When you create the Windows NT source files on the network share, create an $OEM$\C folder below the distribution folder and then copy the tag file (Cdrom_w.40 for Windows NT Workstation and Cdrom_s.40 for Windows NT Server) from the root of the CD-ROM to this folder.

This causes the tag file to be copied to the root of the C drive during the text-mode portion of Setup, and prevents the dialog box from being displayed.

STATUS

Microsoft has confirmed this to be a problem in Windows NT version 4.0. We are researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available.
