    Windows 8


    So I'm on a Windows 8 laptop, now if my computer is UEFI, is there anyway to switch it to Legacy?

    Hello Alamir, and welcome to Eight Forums.

    Yes, but you would have to reinstall Windows 8 to do so.

    Clean Install - Windows 8

    Clean Install with Windows 8 Upgrade

    Ok, so how would I switch it by reinstalling? I am still not very sure.... I know I need to reinstall Windows 8, but other than that, I'm clueless about what I need to do to change it....

    Please go ahead and create a new thread for this issue since it will be detailed and go off topic from this tutorial.

    Create Bootable USB or DVD with Windows 8 ISO

    I tried installing the ISO file on my 4gb file using Rufus and Windows7 Tool but both failed. The iso file is 3.63 and 3.8 on disk and my flash drive only has 3.74.

    So.. I put the iso on my old iPod and was able to successfully use the Windows 7 tool to get the iso.

    So if I boot my iPod as a flashdrive which was able to successfully have its iso contents on it, I would be able to install W8.1 right?

    Penny,

    I've never tried booting from an iPod, but if you are able to, then you should be able to.

    If not, then it may be time to get a larger USB flash drive.

    Ahh.. I see.

    Thing is I have like 5 different flash drives and they are all 4gb. Buying a new one seems pointless.

    Thanks anyway. If the iPod works, then it works but if it doesn't, I'll borrow a flashdrive somehow I guess.

    Thank you for all your help and the tutorials.

    Windows 8.1


    I'm seeing inconsistent results when checking (on a clean windows 8.1 install)
    Option 1: No EFI partition on boot disk (I actually have two bootable drives - the other has an EFI partition, but I don't boot to it)
    Option 2: BIOS Mode: UEFI
    Option 3: Detected boot environment: EFI

    Any idea what would be causing this, or does the article need to be udpated? I'm wondering if I remove the 2nd bootable drive (which I plan to do), will it start reporting Legacy boot? For boot selection, I get what seems to be the UEFI boot screen (with mouse support...etc).
