    Have you tried this from a cmd prompt?

    Code:
    shutdown /fw /r


    /fw Combine with a shutdown option to cause the next boot to go to the firmware user interface.

    /r Full shutdown and restart the computer.


    If this command line works successfully, it should produce a start menu allowing access to UEFI / bios settings.

    Sorry, but a non-booting computer means no commands can be accomplished. To identify/verify hardware issues I use Bootable Linux LiveDVD or Bootable Linux LiveUSB, most versions have lots of driver support and also can be used to recover user data onto a USB drive, can even run programs that are included.

    Another check that will help is whether the BIOS can be accessed, it loads before any Operating System. If it opens one can see if devices are being recognized such as memory modules, storage drives, etc.

    A number of years ago I got all my devices on a UPS after having a motherboard damaged by power bumps, the sudden fail and start of the power.

    Was that line directed at me?

    Did something change after post #20?

    I was under the impression the OP booted from a stick and was able to launch a cmd window.

    Pardon me in advance if I misunderstood your post.

    The only thing I am able to do is boot with the ISO USB drive. Hot keys are not opening BIOS and No option to get to BIOS in the advanced troubleshooting on the front end of the ISO.

    All I've been able to do has been with the cmd prompt.

    To enter BIOS from the Win ISO USB drive:
    - Boot from the Windows installation disk/USB stick with Windows setup.
    - Wait for the "Windows Setup" screen:
    - Press Shift + F10 keys together on the keyboard. This will open the command prompt window:
    - type SHUTDOWN /R /FW /T 00



    It should restart and enter BIOS

    Can you reset BIOS by removing the battery and putting it back?

    shutdown /r /fw does not work on BIOS based machines as per the following tutorial:

    UPDATE:
    I was only just this morning able to get back to this.
    I had to help cover a second account at work in addition to my own and got overloaded yesterday. I plan to get to "the lost boot saga" by late this afternoon and will post early this evening results of any diagnostics run and fishing with cmd code.

    For what I know, it has UEFI firmware (BIOS)
    The drive is GPT and has a Fat32 partition.

    just now able to get back to this... referring to your comment and copy of my screen shot above. Before coming here following a suggestion on a different page. I reformatted that FAT32 partition (vol 3) assigned letter G labeled it Grec.

    If you are correct ... my Format of that Vol would have erased the UEFI firmware (BIOS) ???

    I did just try this... idk where to proceed from it though...

    whatever I did using bootsect did something where now when trying to restart w/o the USB ISO when trying both shift+f10
    and F12 Msg pops up saying F12 Boot Options but then it ends with No Boot Device Found
