    Can't seem to make a working bootable UEFI USB stick

    Hi. As the title says. I am trying to make a bootable UEFI USB stick.

    For example, I want to clean install Windows 10 Pro 64bit. I have updated my PC to Win 10, but now would like to clean install having activated my update,

    I have used the Microsoft Media Creation Tool and created a Windows 10 64bit USB stick. But I cannot boot from it. When I restart my PC I press F8 and select the UEFI Sandisk 32 GB USB stick from the menu, it simply boots into the BIOS.

    Can someone please guide me through, step by step,as to what I need to do, both in creating the USB stick in the first place (assuming I have done it wrong), plus what setting I need enabled or disabled in the BIOS.

    FWIW. My PC will UEFI boot into Windows normally, I just want to boot into UEFI mode from a USB stick.

    Thanks.

    I just checked my recently created Win10 USB flash drive - it is formatted as FAT32. If my memory is correct UEFI requires GPT format - my guess is that is the problem. If I'm wrong others will say so and offer a solution.

    Download Rufus and set it as GPT. Leave everything else as the default's and point it to the Windows 10 iso file and click on start . Then bot from the usb stick and select the boot order in your uefi as I beleive EFI and your usb stick's name. It should be at the bottom of the list.

    Thank you for the reply.

    I have tried Rufus, and it appears to make a 'good USB', all the files are there on the USB stick. However, I just cannot get my system to boot from it!

    As the PC is booting, I press F8 and select 'UEFI Sandisk...', the name of my USB stick, but it just drops me to the BIOS setup page.

    I do actually have a bootable USB disk I created just after I got the Mobo in January and that works. I am sure I have created this one the same way, but it won't work.
    My PC boots into Windows via UEFI no problem. I can make it boot no-UEFI no problem too, just not UEFI USB!

    HELP!

    No problem. I tried F8 with UEFI Sandisk 8GB and took me to the BIOS instead, so I went to the Boot Override and worked from there. Don't need to disable in the BIOS for this one. Please do and good luck.

    Just got home and tried it. Still a no-go. This has me stumped.

    That's weird. I made it via Daemon's Write Bootable Image to USB, tap F8, didn't work, went to Boot Override instead and worked.

    didn't read thread, sry.

    but this might help; look at step 11:
    http://www.eightforums.com/tutorials...e-windows.html

    also, i don't think UEFI works with 32bit.

    and i might not work with a multi-install ISO (It didn't for me...)
