Windows 10 Boot Menu Problem (Have to load OS manually every time)

@cereberus
Where to confirm that? I am sorry to say I don't have much knowledge on this aspect as I am the basic user. I only have knowledge of "Boot Options Menu" so I posted Image of that.

@CountMike
Does the last image with name "Boot Options Menu of my Laptop - For Reference" don't give any information about that? If not where can it be found so that I will check

This is what finally I understand after changing Boot Options to default mode now.

Reference Image (Boot Options Menu)

Windows 10 Boot Menu Problem (Have to load OS manually every time)-boot-options.jpg

In default Boot options, "Legacy Support" in above image is Disabled which in-turn disabled "Legacy Boot Order" and enabled "Secure Boot". With these settings, it is shown that "No Operating System Found" and when I press F9 for Boot Options Menu, it shows nothing when previously it is shown as "Boot From EFI File" atleast to load my OS

And then I disabled "Legacy Support" then in-turn it enabled "Legacy Boot Order" and disabled "Secure Boot". Now by pressing F9 I can enter Boot Options Menu where "Boot from EFI File" option was shown which can load OS.

I hope this gives some information.

What's happening here is that my OS is on HD1 but the BIOS is looking for the efi bootloader on HD0, I either need to create a efi partition on my HD0 and tell it to boot to my Windows partition on HD1 or I need to switch the hard drives so that my BIOS can boot from HD0.

**Note - This explanation helped me in understanding the problem precisely and is taken from HERE

This tutorial from tenforums solved the problem

- Boot the computer using the Windows 7/8/8.1/10 installation media.
- On the first screen, press SHIFT+F10 to bring up the command prompt.
- Run the following commands at the command prompt.

Code:

diskpart
list disk
select disk # Note: Select the disk where you want to add the EFI System partition.
list partition
select partition # Note: Select the Windows OS partition (# number) or your data partition.
shrink desired=100
create partition efi size=100
format quick fs=fat32
assign letter=s
list partition
list volume Note: Note the volume letter where the Windows OS is installed.
exit

bcdboot X:\windows /s S:
Note: Replace "X" with the volume letter of the Windows OS partition.

BCDBoot copies the boot files from the Windows partition to the EFI System partition and creates the BCD store in the same partition.

Remove the Windows installation media and restart the computer into your BIOS settings and set the SSD as the First Boot Device.

***Note - Above Tutorial is taken from Moving / recreating EFI partition in this forum. Thanks to @Kyhi for providing this Tutorial.

And I also disabled "Legacy Support" in BIOS Options after following this tutorial. This tutorial worked like a charm and resolved the issue.

Finally I want to say Thanks to each and every one replied me in resolving this issue.
