I'm now wondering if I need to leave the Windows 7 installation process for much much longer, maybe 30 mins to see if it gets past the initial logo animation?
    If you're thinking is correct... I will love your brain forever and ever... no homo

    I also tried forcing a boot from the one time boot menu (f10) and got the same result as above.

    I tried enabling and disabling UEFI secure boot in the BIOS but no luck.

    1) Bad disc burn, remake disc.

    2) uEFI/BIOS firmware not set to boot uEFI CD/DVD's.

    Is this something we can fix ourselves?

    Ok so 1 I can test as presumably if the DVD boots from numerous other PCs it should almost negate the "bad burn" scenario.

    Point 2: I have tried turning on and off the uEFI options in the BIOS. How do I know that my DVD is uEFI however? I have two mediums currently:

    1. an original ISO provided by Microsoft of Windows 7 Home Edition 64 SP1. Can I tell whether this is uEFI?

    and

    2. A Patched Windows 7 installation uEFI USB stick.

    Only on a uEFI PC.

    original DVD provided by Microsoft of Windows 7 Home Edition 64 SP1 will be uEFI.

    May be bad burn.

    Yes, set the uEFI/BIOS firmware to boot uEFI CD/DVD's.

    NOTE: Check your manufacturer's uEFI BIOS manual for settings.

    Ok so I followed this tutorial once more: UEFI Bootable USB Flash Drive - Create in Windows

    I also ensured "confirm-SecureBootUEFI" returned false before trying to get a UEFI device in the one time boot menu.

    I also tried toggling Fast BIOS on and off.

    I've also tried the USB stick on three different USB slots on the Samsung laptop.

    I've tried booting the USB stick from an acer aspire one laptop and it boot successfully and gets beyond the animated windows 7 logo so the USB stick is fine.

    All thats listed in the one time boot menu (f10) is the devices:

    1. SATA CD:: Matshitadvd-ram -----

    2. WIndows Boot Manager

    3. SATA HDD:: -------

    So the USB stick is not being recognised by this Laptop as a bootable device. This is the third USB stick I have used.

    No option to do that - even updated the BIOS too!

    Ive just tried having the windows 7 Install USB insytalled and then forcing the BIOS to ONLY see the USB HDD and disabling all other boot medium. Ive then tried to use the recovery F4 keypress to see if this will force widnows 7 to load from the USB.

    No Luck It simply boots into the rescue partition on the internal HD.

    If you have no option to boot uEFI CD/DVD in the uEFI/BIOS firmware, your Acer Recovery Disc will not boot to reinstall.
