What:
Create a bootable USB drive to be able to install ESXi in a server/host without the need for a CD/DVD drive.
How:
I am using Rufus, due to it is really easy to use, of course, there are a lot more similar tools...
1. Register/Login to Vmware and obtain ESXi 6.5 U1 iso (Latest version, to the date)
