instructions, see "Deploying the Operating System using the OS Deployment
Wizard" in the Dell Unified Server Configurator - LifeCycle Enabled User
Guide at support.dell.com/manuals.
CAUTION: Reinstalling the operating system on existing disk drives erases all
installed applications and data.
Locate the operating system media that came with the system and proceed to
the operating system deployment option from USC-LCE. Follow the
instructions on the screen to install the operating system.
