    Hi all,

    I found the way how to prevent my Z boot from EFI. This may also apply to any other new Sony models.
    Hit ESC when turn on your VAIO to lauch boot menu.
    DVD Windows x64 is now booting. You will notice "Press any key to boot from ..." in graphic text mode. Then Bootmenu will appear. Select Boot Manager.
    You will see following options:
    - ACPI....../...../CDROM(Entry1) --> EFI Boot
    - Model name of DVD drive --> BIOS Boot
    - Model name of hard drive --> Hard drive Boot
    Select second option and DVD will boot. You will see above text in DOS format.
    In concluded, if you see DVD boot text in graphic mode --> EFI boot
    If text is in DOS mode --> BIOS mode --> You can install x64 Windows whatever you want.

    100% working guaranteed.
