OS deployment
- Windows operating system deployment may intermittently fail with the following error message:
A required CD/DVD drive device driver is missing. If you have a driver floppy disk, CD, DVD, or USB drive, please insert it now.
Reboot to LC and retry until the operating system is successfully deployed. - Deployment of Windows Server operating systems (OS) using LC may fail with one of the following messages:
- Windows installation cannot continue because a required driver could not be installed
- Product key required
- Windows cannot find the software license terms
- Remove all the installed add-on devices before starting the OS installation. After the OS installation is complete, connect the add-on devices and manually install the remaining drivers using Dell Update Packages (DUPs).
- To avoid physically removing the hardware, disable the PCle slots in the BIOS.
- Increase scratch space size beyond 32 MB using DISM set-scratchspace command when creating customized deployment. For more details, see Microsoft's documentation.
- LC displays two drive names for some CDs or DVDs, such as the ones containing operating systems.
- If the operating system (OS) selected for installation and the OS on the media used are different, LC displays a warning message. However, while installing Windows OS, the warning message appears only when the bit count (x86 or x64) of the OS does not match. For example, if Windows Server 2008 x64 is selected for installation and Windows Server 2008 x86 media is used, the warning is displayed.
- LC does not support OS deployment on Dell Precision Workstation R7920.
