Windows Server 2008 R2 32 on Dell R720

Hello,

Want to Install Windows Server 2008 R2 32 bit on Dell R720-E52660.

1. I dont have Windows ROK Media for the installation.

2.Will download an ISO image for 2008 R2 32 bit and burn to dvd.

3.I will install the OS using lifecycle controller but not sure it will work because media is not ROK.

I need all the possible ways to install the Windows Server 2008 R2 32 bit with windows drivers without ROK Media.

Im new to the dell server kindly advise.
