When trying to install ESXi on Workstation 11.1 Build 249682, there is no option to select EFI or BIOS. It is there for all other OS's. Any ideas on this.
You can edit the VM from "VM-> Settings -> Options -> Advanced -> Check the checkbox 'Boot with EFI instead of BIOS' -> Save the settings by click OK button", then you can install ESX with EFI. And on VMware Workstation, even you installed ESX with BIOS, you can still boot it from EFI(change the setting in VM settings). But for production systems, just stick to the guide and reinstall the host using EFI instead of BIOS on your hardware server.
The first few times with either checking the EFI box or editing the vmx file caused the load to stop at EFI Network and eventually load the EFI Shell. Last night I tried again and strangely ESXi started the install, it almost got to the end and the stopped with a fault. I have attached the fault message.
Solved, While browsing the Web for a solution, I came across installing ESXi on Workstation 9 and then the Light Bulb went on. I am using ESXi 5.1 U3 and efi doesn't work on Hardware version 11. I first tried Hardware version 9 and that worked then I went to Hardware version 10 and that worked. I tried to upgrade te version and it failed again. So, I'm leaving the version at level 10.
[...] efi doesn't work on Hardware version 11.
That absolutely should not be the case. If it is the case, it's a critical bug that we will want to fix immediately.
Please provide more detailed instructions on what you are doing to trigger the failure. Once again, if you could provide the vmware.log showing the failure ("A fault has occurred causing a virtual CPU to enter the shutdown state..."), that would be very likely to assist us in isolating the problem.
