    You must use VMware Player.

    Edit *.vmx configuration file, add in:

    firmware = "efi"

    If you ever want to force VMware Player to enter BIOS/EFI firmware on next boot, add in:

    bios.forceSetupOnce = "TRUE"

    As far as I know there isn't anything special that has to be done to a DVD (other than being bootable) as far as UEFI goes. Once you boot from it you should get two boot options for it, one UEFI and one normal.

    I will let you know if normal DVD iso works or you need to create special UEFI DVD/iso. Though I used special one. I will try with normal one later and update here.

    This worked for me.

    Copy all files from the Windows 8 DVD to a local folder eg. C:\Win8Media

    oscdimg.exe -m -o -u2 -udfver102 -bootdata:2#p0,e,bE:\Win8Media\boot\etfsboot.com#pEF,e,bE:\Win8Media\efi\microsoft\boot\efisys.bin E:\Win8Media E:\win8pro-uefi.iso

    I'll take your word for that, It's been ages since I last burned a DVD. I do all my installs from USB thumb drives. If I was going to install from a DVD I'd just use one of my Microsoft Windows ISO files.

    I have the toolkit. Looks like that directory is not in my path environment variable so not recognizable as a command.

    Google gave me the info:

    Oscdimg is a command-line tool for creating an image file (.iso) of a customized 32-bit or 64-bit version of Windows PE. You can then burn that .iso file to a CD-ROM or DVD-ROM. Oscdimg supports ISO 9660, Joliet, and Universal Disk Format (UDF) file systems.
