UEFI boot + Windows 8 support?

[raymanyoung]

I am seeking for a VM solution that supports the Windows 8 VMs to boot from UEFI. It seems currently vSphere 5 does not support Window 8 yet and WorkStation 8 does. However from the product description I saw vSphere claims to support UEFI boot but WorkStation 8 does not.

So what's the recommondation here? In order to get both supported do I have to wait until Windows 8 is supported in vSphere?

Thanks!

Did you try this yourself ? - I doubt so ...
at the moment I think it is impossible to run Windows 8 on esxi5 - it only works in Workstation 8

by the way - to run Windows 8 on Workstation
firmware = "efi"
is not necessary

[raymanyoung]

so does work station 8 support UEFI boot?

[raymanyoung]

Sorry I have tried and Windows 8 does not boot on ESXi 5...

[continuum]

yes

[raymanyoung]

My Windows 8 started to install on WorkStation 8. Thanks!

Is there any way that I could choose the boot mode between UEFI and BIOS?

[continuum]

sure - set
firmware = "efi"
in the vmx-file

[raymanyoung]

I set the flag and Win8 server does not boot. Any idea about the failure?

Thanks!

that is expected

you can not change from BIOS to EFI after the VM is already installed - create a new VM if you want to use EFI

Oh yeah. It works now. Thanks a lot!
