    1: = Windows 10
    2: = Windows 7

    Very important to me to understand your system: Why and witch drive did you convert from EFI-GPT to Legacy-MBR (Disk 0 and 2 have signs of a conversion)?

    Problems that I see:
    Disk 0 (storage) has a active partition. Did it once had Windows installed?
    Disk 2 (win7) is MBR but don't have a active partition. Can you boot win 7?

    Hey there,

    I have used Disk 0 for storage ever since I can remember but I can't remember if it had Windows installed on it before unfortunately....I don't think so but could be wrong...

    Disk 2 which is the new hard drive that I bought and converted to MBR. I can boot Windows 7 but only if I press F8....

    On disk 2, did you converted from GPT to MBR before or after installing Win 7? Did you detach disk 0 and 1 before installing win 7?

    Hi,

    I converted before installing Win 7.

    I did not detach any disks......

    Hi

    as the winload.efi is being returned as non signed, its either that the system cant read it or its corrupt,
    more likely the first.

    try looking at this thread

    The big mistake you did was:
    - converting disk 0 and disk 2 to MBR. Windows 7 and 10 can be used with GPT.
    - Not detaching disk 0 and disk 1 when installing Win 7. As disk 0 (data) has an active partition, I would say that the boot loader of win 7 is on disk 0 not on disk 2.

    To find out, disconnect disk 0 and disk 1. If you can't boot, insert and boot from the Win 7 installation disk, go to repair and do a boot repair. Report.

    Bit confused...

    I only converted one disk which was the disk I installed Windows 7 on i.e. Disk 2. Originally the disk was GPT but when I tried to install Windows on disk 2 it said I couldn't and when I looked up the solution...it said to convert the disk to MBR.

    As for disk 0....I haven't touched that myself and it has only been used for storage....

    I'm happy to do as you say but just to be clear...when I press F8 after turning the PC on it brings up the boot menu and all I do is select the disk with windows 7 on it and it boots up fine....

    Let me know your thoughts and if nothing has changed I will follow your instructions!

    From the disk management image you posted:
    - The only disk that I see that is normal is disk 1 (win 10). It is a UEFI-GPT disk, has a EFI partition with the boot loader, has a OS partition and two recovery partitions (normally is only one - Did you use a disk from another computer?)
    - Disk 0 (data) has a GPT protective partition so I believe it once was a GPT disk. (You can see a EFI partition on disk 1 (win 10) and disk 2 (Win7).

    Some explanations.
    - On a Legacy-MBR, you choose a disk to boot from, BIOS takes the boot sequence to MBR on the disk (fist track on disk) that takes boot sequence to a Boot Loader on a partition (normally C: or System Partition on OEM (Dell, HP, etc)) and this partition is flagged as Active. Master boot record - Wikipedia
    - On a UEFI-GPT, you choose a boot loader on the Fat32 EFI partition. This boot loader take the sequence to the OS partition. On a UEFI-GPT disk you can have more than one boot loader and more than one OS partition.

    As the data disk is on the fist SATA port, is seems that, when installing Win 7, as you didn't detach disk 0 and disk 1, it has installed the boot loader on disk 0 as it is flagged as Active. In other words, you may have Win 7 boot loader on disk 0 and the remaining OS on disk 2.
    When you launch the boot menu (F8) what are the options (please list all them)?
