    My understanding of "Legacy BIOS Mode", and I may be wrong here but I'm 99.99% sure of myself, is the exclusion of any (U)EFI/GOP advantages.

    Hence showing not supported, nor selectable for use.

    Windows installed in Legacy mode is the problem, you cannot use Ultra Fast boot with Windows 8 unless it is installed in UEFI booting mode.

    To do that, in the the BIOS set CSM to Disabled, or set Secure Boot to Enabled. Then let Windows format the OS drive (as GPT) during the installation.

    You cannot disable CSM or enable Secure Boot with a Legacy OS installation, that will fail.

    Thanks for the replies!!!!



    Actually I didn't mention I can enable ultra fast boot from the bios but it will not boot , after restarting the pc it will log in into bios again.


    I guess that should be the issue than it doesn't work

    Soon I will buy an SSD and reinstall windows on the SSD from the scratch because if I understand correctly I need to reinstall windows again . ( and I think I need to have a partition free Storage device , and my HDD got 3 partitions full of stuff )

    thanks a lot!!!

    Yes, you can enable Ultra Fast with a Legacy installation, but it won't boot as you saw, and forces you into the BIOS to change the setting.

    A new SSD will work well for UEFI booting, and a new OS installation, which is required. Yes you would lose all the data on a HDD since Windows will format any drive when you do a UEFI booting installation.

    Here's a link to a guide about doing a UEFI booting installation: UEFI (Unified Extensible Firmware Interface) - Install Windows 8 with

    The guide may tell you to enable Secure Boot to enable a UEFI booting installation, which will work, but that also sets CSM to disabled. Instead you can just set CSM to disabled before you start installing Windows and it will work fine. You can use Secure Boot if you like, but it is not required, all you need is CSM set to disabled.
