    How do I boot from CD in 8.1?

    My Advent laptop has gone into the dreaded automatic repair loop in Windows 8.1 and I have had enough of it! I want to downgrade to windows 7 but when I go into the BIOS boot configuration to change the priority to CD drive I find I don't have that option. All there is is "> UEFI Boot Drive BBS Priorities" and then "1st Boot [Windows Boot Manager]".

    Can anyone tell me how to make it boot from the CD drive please?

    I would enable boot menu, in the BIOS, which would probably get F-12 assigned to it.

    I would insert the CD or DVD & press F-12 at startup to get the boot manager & select the CD or DVD to boot from.

    Thanks David

    I've just tried it with an XP disc as I am waiting for my mate to drop of the windows 7 and although I heard the CD drive kick in the laptop still went into the automatic repair loop?

    You may have safe boot enabled. If your Laptop has a Windows 8 logo, you probably have. Your CD drive kicks in, cause the BIOS checks all drives, but then it finds that the XP installation CD has no valid signature to safe boot and does not offer it in UEFI/BIOS nor does it boot from it.
    Disable secure boot then to boot from XP CD.

    Also you may try different Keys, with my computer F8 brings up the UEFI/BIOS boot menue, from which I can select the boot device.
    And when booting from CD there is often a message displayed for a short time saying something like "press any key to boot from CD". Maybe with XP it was the other way around ("Booting from CD, press any key to abort"). It is a long while I've bootet XP the last time from CD. I sometimes manage to miss that short while, so the computer boots from HD then.

    If you have an OEM PC that came with Windows 8 64-bit preinstalled and you want to install Windows 7 64-bit, then you must disable Secure Boot, because Secure Boot is not compatible with Windows 7.

    - You do not need to change the boot order of drives in your computer's UEFI firmware (BIOS).
    - Connect your Windows 7/8 64-bit USB flash drive or insert your Windows 7/8 64-bit DVD.
    - Restart the computer.
    - Press the correct key to enter the boot menu (see this link for help).
    - Select your USB/DVD from the boot menu.

    If Windows 7 installation does not succeed in UEFI Boot Mode, try installing Windows 7 in Legacy BIOS Boot Mode.

    Here is info about UEFI Boot Mode (installing using the GPT partition style) and Legacy BIOS Boot Mode (installing using the MBR partition style): link

    BEFORE you make that move, check the manufacturer's website and ensure that there are Win7 drivers for your machine.

    Not all preinstalled Win8 machines can be "downgraded" to Win7 -- due to lack of drivers.

    This is indeed correct. It can be downgraded but the computer won't work properly without designated Windows 7 drivers from the manufacturer. -personal experience-
