Issue 13 Unattended installs abort when using UNATTEND.TXT file with the OEMPreinstall flag set.
Description
Solution
Unattended installs abort with the following message:
File [filename] could not be loaded. Error code is 18. Setup cannot
continue.
When installing any edition of Microsoft Windows Server 2003 on a ProLiant
server that has an embedded virtual install disk, the error message listed above
may be generated when using an UNATTEND.TXT file that includes the
OEMPreinstall flag.
The problem occurs because the Windows Server 2003 Installer interacts with the
embedded virtual install disk when the OEMPreinstall flag is set in the
UNATTEND.TXT file, but no files are specified to be preinstalled.
In order for this error condition to be triggered, all of the following conditions
must be met:
Windows Server 2003 (or later) installation.
•
• Installation must be performed using an UNATTEND.TXT script.
• The OEMPreinstall flag must be set in the UNATTEND.TXT file.
• The UNATTEND.TXT file must NOT specify any files to be preinstalled.
The server must have an active virtual install disk.
•
Note: Installations performed using SmartStart, Rapid Deployment Pack, or "Disk
Image" (i.e., the operating system image is copied to the hard drive) are not
affected.
To work around this problem, use one of the following methods:
Preferred method:
If the OEMPreinstall flag is set to Yes in the UNATTEND.TXT file, set the
"DisableVirtualOemDevices" flag to Yes in the [UNATTENDED] section of the
UNATTEND.TXT file, as shown in the following example:
[UNATTENDED]
DisableVirtualOemDevices=Yes
Other methods:
Avoid setting the OEMPreinstall flag to Yes in the UNATTEND.TXT file if files are
not specified to be preinstalled.
OR
Disable the virtual install disk in the advanced options of the ROM-Based Setup
Utility (RBSU) for the affected server.
