I downloaded the ISO's for Windows Server 2016 and 2019. I uploaded them into my local datastore and I am now trying to install them into vSphere ESXI 6.7 but I keep running into the same errors with EFI. Please help.
Can you confirm that the installation ISOs are bootable, mapped to the VM's CD-ROM drive, and in the state of "Connected", i.e. either by enabling "Connect at power on", or by connecting them after the VM has booted, followed by a "warm" boot (CTRL-ALT-INS).
