In doing some research and pinging a few of our ESXi experts internally, I found that UEFI PXE boot support is actually possible with ESXi 6.0. There are many benefits with using UEFI over BIOS, a recent article that does a good job of explaining the differences can be found here.

You also could boot an ESXi ISO using UEFI, but we did not have support for UEFI when it came to booting/installing ESXi over the network using PXE and other variants such as iPXE/gPXE.įor those of you who may not know, UEFI is meant to eventually replace the legacy BIOS firmware. Historically, we only had support for PXE booting/installing ESXi using the BIOS firmware.

He was helping a customer who was interested in PXE booting/installing ESXi using UEFI which is short for Unified Extensible Firmware Interface. A couple of days ago I received an interesting question from fellow colleague Paudie O'Riordan, who works over in our Storage and Availability Business Unit at VMware.
