It took me sometime but ultimately was able to hit the following -
https://superuser.com/questions/965751/how-to-access-efi-partition-on-windows-10
and did the following -
PS C:\WINDOWS\system32> mountvol P: /s
PS C:\WINDOWS\system32> cd P:/
PS P:\> ls
Directory: P:\
Mode LastWriteTime Length Name
---- ------------- ------ ----
d----- 10-03-2018 11:44 EFI
PS P:\EFI> dir
Directory: P:\EFI
Mode LastWriteTime Length Name
---- ------------- ------ ----
d----- 15-02-2018 19:21 Microsoft
d----- 15-02-2018 19:26 Boot
d----- 25-06-2019 07:08 debian
As can be seen it can be in EFI partition but not within Boot, dunno
if that is normal or not.
within the debian directory it shows -
PS P:\EFI\debian> dir
Directory: P:\EFI\debian

> How did you change Debian boot mode to EFI ?
I don't think I did that, although am not sure. Is there a way to see
if that has been done or not ?
What I remember doing is being asked to try to change the BIOS from
legacy mode to a UEFI and see if the grub menu appeared. I tried and
did that and it worked for quite sometime.
> Can you see a "debian" entry in the UEFI boot menu or boot order ?
Sadly no, in the UEFI boot menu or boot order I just have the MS boot
manager and one without. It would take a reboot but if needed can
write down the exact thing but it definitely doesn't mention anything
remote to debian.
If I use the other option I just get a blinking horizontal bar/cursor
where I can't do nothing.

Haven't tried that as of yet :(
