    Sry, I had hoped to give this issue my full attention today, but Im having other issues on my work PC that I had to focus on today. Likely will be giving any attention I can tomorrow as well. But I'll follow up on the steps suggected in this thread (for the HDD booth issue) either tomorrow or Wednesday. When it rains, it pours T_T

    Oh, and I don't know about UEFI on a GPT disk for sure, but If I had to take a guess, I'd say UEFI. But Windows is installed on the internal HDD, not on either of the external HDDs.

    I was able to confirm that neither external HDDs are active.

    Is your Win 10 installed as UEFI on a GPT disk?

    As your External HDDs are only for data they shouldn't be set as active (boot able).
    Open Disk Management (C:\Windows\System32\diskmgmt.msc) and look if one of those External HDDs is set as active.
    If you have one, set it as non active.
    As pointed out in post 7
