 I am able to open the H20 Setup Utility using F2. Ive reset Setup Defaults, restarted it and still it says No Bootable Device.
When I put the HDD into another laptop everything boots up just fine. But for some reason this laptop isn't reading any HDD.
Originally I had a 1tb HDD running Windows 10 Pro in this laptop but accidentally gave it away. I have a few HDDs and gave the 1tb HDD away thinking it was the 500gb one.
I'm getting off track here.
The Setup Utility is reading the HDD but when I exit out It says No Bootable Device. 
When I load Setup Defaults it keeps turning on secure boot, which I keep disabling.
Also previously when it was running fine it was running in Legacy Mode but I believe it should be in UEFI. Correct me if I'm wrong.

Please help me out with this.
Here are a couple pictures so you can see what I'm seeing in the Setup Utility.

    For this to have happened, Windows was installed in legacy BIOS mode and the boot HDD converted from GPT to MBR partitioning. As such, It can no longer boot with a UEFI bootstrapper which requires a GPT partitioned boot HDD.

    If you want to convert it back to GPT partitioning, I'd advise that you first copy any personal files using a 2.5" USB-to-HDD adapter (less than $10 from Amazon) onto another machine. Then reinstall Windows on the HDD in UEFI mode. In order to disable secure boot in UEFI bootstrap you often must first set and save a BIOS supervisor password. Then re-enter the BIOS with the password to change security settings like this.
