I downloaded the ESXI installer from VMWare for V8.
I checked and the MD5 matches with what's listed on the download.
I'm using a Mac to write the iso to a known working USB (using DD)
The server will not boot in uefi or bios mode from the USB - I get the message no bootable disk found.
I have an Ubuntu ISO and if I use the same dd command to send it to the same USB device it boots on the server. This rules out the dd command being the problem, and rules out the USB device being a problem.
Why won't the esxi v8 iso not boot? I can't figure it out.
EDIT - I just created a VirtualBox vm and booted from the iso attached to the virtual CD and it booted the installer, so the image is the correct one.
