Windows Server bare metal Provisioning

Hi Team,

I want to deploy windows server 2012 | 2016 | 1709 | 2019 on bare-metal servers, but not getting very clear dosucmetation or steps what exactly need to follow, went through the below video but in video speaker confuses too much ( i am not critising here just said after watching the video & its my view it may be differ for others so please dont feel bad )

Incase anyone has done the implementation would appriciate if share the steps.

Thanks in advanced.
