    How to Boot from a USB Drive within Windows 8 and 8.1


    information   Information
    This tutorial will show you how to boot from a USB drive from within Windows 8 and 8.1.

    Note   Note
    This is a per usage option that will not configure Windows to always boot from the USB drive.

    If you have a UEFI Windows 8/8.1 installation, then you will need a bootable UEFI flash drive to be able to boot from it using the method in this tutorial.





    Here's How:

    1. If you have fast boot or ultra fast boot enabled in your UEFI firmware settings, then you will need to temporarily disable fast boot or ultra fast boot to be able to boot from a USB.
    2. Connect a bootable USB drive to the USB port on your PC.

    3. While in Windows 8 or 8.1, boot to Advanced startup using either option 1, 2, or 3 in the tutorial below.
    4. After the computer restarts, click/tap on the Use a device option. (see screenshot below)

    5. Click/tap on the USB drive that you want to use to boot from. The computer will now restart and boot from the selected USB drive. (see screenshot below)

    That's it,
    Shawn

    Is there an advantage over the changed boot order method ??

    Hey Wolfgang,

    This method doesn't require having to disable Secure Boot, enable CSM, or disable Fast Boot in UEFI settings to boot from the USB. Well, at least I didn't have to on a Surface Pro 2, HP Envy laptop, or my desktop (see my specs) that all have Windows 8.1 installed with UEFI.

    However, if you are not able to boot into Windows, then you'll need to use the boot order or boot menu method instead.

    Thanks for that. Another way is to set the Change Windows To Go startup options setting to yes. It will then boot from whatever USB you have plugged in. Note I've only tried this on mbr installation of 8.1 Pro - not sure about other versions.


    It is easier than changing the BIOS I think.

    Thank you Adam. You read my mind. I'm working on another tutorial for later just for that with a command and gpedit option as well.

    Hello SevenT, and welcome to Eight Forums.

    Double check to see if this below may be the issue for your F12 boot menu.

    Why can't I get the F12 Boot Menu to work on my notebook or netbook?

    Hi Brink,

    Thank for your reply. I think win 8 have lock some think. My current win 8.1 is not actived. And when i do as your link it doesn't go to bios when turn on and press f2. It still go to windows.

    But when i logged in my pc, and press Shift + Restart > troubleshoot > advanced option > uefi firmware setting . It log into bios. I already enable F12 boot.

    Another thing is when i choose boot from HDD in your step 3. Or when i try to safe mode, it still run into windows. So my normal way to renew win is use command prompt to select file in my hdd. But this way can't format the system (C) drive and it's leave a old file win?

    Any solution?
