How to Create Bootable vSphere 6.7 Installer USB Flash Drive

VMware released their latest version vSphere 6.7 on April 2018 and I have shared the details on one of my Blog post. As we know there are multiple options like remote management console (KVM, ILO, iDRAC), CD Drive to install the ESXi to Physical Server. However, some cases due to firmware issue, limited number of ports on switch remote console license unavailability or CD ROM unavailability we will have challenges to install ESXi, in that case bootable USB with ESXi installer will help to install the hypervisor.
