    Ok, I can confirm that creating a Windows 8 Professional (64-bit) bootable USB stick as described in this tutorial does work with UEFI. It seems theog is right - Toshiba (or at least my Ultrabook model) only allows Windows 8 to be installed through UEFI... Wonder why though?

    Hello mathemagician,

    Odd, I thought you had a CSM and UEFI option?

    However, I'm happy to hear that you got it installed using UEFI like you wanted.

    Hi Shawn,

    Yes, there is a CSM and a UEFI boot option, but no CSM and UEFI, which, according to theog, would be required to install Windows 7 through UEFI.

    All I got working was to boot from a Windows 8 UEFI USB stick but I haven't installed it yet. Might do it since before I swapped the HDD for the SSD and it was booting Windows 8 through UEFI (HDD + 32 GB mSATA SSD Cache) it was a hundred times faster than now with an SSD booting Windows 7 through CSM.

    So what theog said about Toshiba purposely omitting the boot setting in the BIOS required to install Windows 7 through UEFI seems to be true, since it worked first time with a Windows 8 boot stick.

    mathemagician,

    You might also check to see if there may be a newer BIOS/UEFI firmware update available at Toshiba for your Satellite U940 that may add it or address any other bugs.

    That was my first thought, unfortunately I already have the latest BIOS version.

    In that case, you might contact Toshiba to see if asking them about a possible update may be in the near future, or if they are no longer providing firmware updates. Who knows, you might get lucky.

    I have a Toshiba Satellite and all the steps above works fine to me up to where the Windows Logo shows up with the 'Starting Windows' message and it freezes there forever. My Toshiba Model is Satellite P875-S7310. HELP! THANKS!

    Hello Jalexbon, and welcome to Eight Forums.

    I believe that you may have posted this in the wrong section since what you described is not in the tutorial. Please provide more details to help clarify.
