Installing W8.1 - Legacy vs. UEFI - Dell XPS15 - Problem!

    To boot a flash drive, you need to boot into the Bios and select the Boot Device Menu from there, or be able to use the F keys to open the Boot Device Menu. It is very hard, with the quick boots, to get responses from F keys. That is why I just go into the bios instead of trying to open the boot device menu.

    As long as you are working with Windows 8, you do not have to disable Secure Boot or set anything to Legacy.

    Should I change that?
    Do not change the default UEFI firmware (BIOS) settings (for example, the boot order of drives or Secure Boot).

    - But how do I boot into the BIOS without using F2 ?

    @genet
    - How do I get to see this blue screen?
    - I don't have a Windows disk, since the XPS 15 is a laptop.

    Sorry if I ask the obvious, bought the notebook one week ago, find 8.1 still a bit baffling after trusted old 7...

    It depends on your system. On my ASUS motherboard, I use Delete.

    And when you describe tapping the key during boot, it is almost more like releasing the key, since you are basically holding it down by tapping quickly enough.

    But Genet's suggestion will also work if the USB drive is plugged in before you boot the system.

    Edit: On my Dell system, F2 got me in, but I start tapping as soon as it looks like the restart has finished shutting down. If you wait for something to show on the screen, you are probably too late.

    But what if Windows won't startup properly?
    Can I enter this menu to use my usb stick recovery?

    @saltgrass

    Startup Options Menu - Boot to in Windows 8

    OPTION FIVE
    Boot to Advanced Startup Options using a "Recovery Drive"

    1. Boot from your created recovery USB flash drive.

    2. If displayed, click/tap on your keyboard layout language.

    3. You are now in the Startup Options menu at boot where you can choose what option you would like to do.

    OK, as I understand it's not possible to boot into a usb drive just to test "what if", but only from 8.1 itself or at the second failure to start...
    Learned not trust to MS too much LOL...

    Read @genet last post, it clearly says that you should boot to your Recovery USB and select your language bringing to the start up Options menu?

    - Do not change the default UEFI firmware (BIOS) settings (for example, the boot order of drives).
    - Connect your Windows 8/8.1 Recovery USB flash drive.
    - Restart the computer.
    - Press the correct key to enter the boot menu (see this link for help).
    - Select your USB flash drive from the boot menu.

I have an Acer V3-731. Owner's nephew somehow put W-8 Enterprise on. Received a complete set of Recovery CDs from Acer. I want to do a complete recovery, no data. First CD, "System" started and said needed UEFI The BIOS is set Security Supervisor Password-Clear Secure Boot Mode-Standard
and if so, will it perform slower? Or only boot time will be affected? Any other disadvantage of doing so? Thanks
