Friends, I do have an extra motherboard.
Gigabyte GA-78LMT-S2 R2 (Only 2 RAM slots)

DOES THIS SUPPORT UEFI BIOS?
I AM CONFUSED A BIT...


Came to know,that this motherboard supports Hybrid uefi bios.

This looks like your motherboard - Gigabyte's Hybrid EFI

The article although is regarding Linux, primary information should be correct. I think you could use that as a test platform in your case for Windows.

You may have issues with activation though due to changed motherboard.

How I came back???:--->

1). Shut down PC.
2). Disconnected all wires(USB, Sound,..)and Power cable.
3). Opened Cabinet.
4). Took out all RAM modules each, one by one.
5). Took out the GPU card.
6). Took out CMOS battery.
7). Resetted CMOS by touching the reset (2-pin) switch with a screwdriver for more than 1 min.
8). Attached back(Installed back) all the RAM modules.
9). Installed the GPU card in the second PCI-E slot of the Motherboard.
10). REINSTALLED WINDOWS-10(64-bit) PRO AGAIN.

VIOLA!!! It works.

So, it was Dust or incorrect placement of modules.
Dust. Just had to brush it off. As for RAM modules, each of the 4RAM sticks is from CORSAIR with the same frequency /latency configuration.
Based on details available so far, you should be fine. Try it.
Yeah, Friend...Windows 10 Pro(64-bit) installed flawlessly. HDDs were in GPT format.
So Both of my Desktop-PC'are running flawlessly with Windows 10(Pro/64bit).

Again, Thank You all.

Sorry @sling-shot , after installing mini tools partition wizard, I found that HDDs were converted to MBR while installing Windows 10 by the Gigabyte GA-78LMT-S2 R2 (HYBRID UEFI) motherboard.

You can't set up BIOS onto UEFI mode or lay partition as GPT for HDD's.

Inside BIOS you've 3 options (modes) for Booting:--->
UEFI
AUTO
NON-UEFI

Even choosing EFI as default boot,the BIOS is still LEGACY!!! No UEFI mode!!!!!!!!!!!!!!!!!!!!!

THE MOST SHITTIEST OF MOTHERBOARD BY GIGABYTE!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Friend, @whitestar_999 any new ideas?

Gigabyte introduced Hybrid-EFI firmware in their boards a decade ago when UEFI was not that mainstream. It’s main selling point was ability to boot off 2 TB which is limitation of MBR.

To force the firmware to behave like EFI you need to set this switch to EFI (Which you already did) and might need to manually initialize the disk (< 2TB) to GPT before installing Windows using say DISKPART. Then your Windows 64-bit OS (Windows 7 or above) should install in EFI mode with GPT partition scheme on the HDD. The firmware still remains more or less traditional BIOS with a sort small functionality of EFI introduced in it.

I had one such board and I had done extensive testing using this mode in EFI mode. Back then it was Windows 7 64 and it warned me that the BIOS may not supporting booting to this disk, I still continued and it worked with EFI & GPT actually.

Despite being Hybrid-EFI, it had basic coverage of UEFI. You could even boot to EFI Shell externally using pen drive.

One limitation on Hybrid EFI was there were no UEFI variables. There weren’t UEFI boot entries unlike full-fledged UEFI systems. You had traditional Boot menu pointing to SATA HDD1, HDD2 etc and when set to EFI, firmware was designed to just go ahead and look for Bootx64.efi at /EFI/boot folder on EFI partition, without being aware of anything else. All Windows versions capable of UEFI booting have that fallback mechanism anyways.

The firmware is deigned to switch EFI when it detects > 2 TB HDD. Else it might fall back to BIOS by default.

Also, these boards were designed back in 2010-11 when Windows 7 was mainstream, so results with Windows 10 may not be predictable, while the UEFI booting is still the same. You may need to experiment.

To test if you are actually booting in EFI or not when switch is set to EFI, try the following

Download UEFI 64 bit shell from this link edk2/Shell.efi at UDK2018 · tianocore/edk2

Rename it as Bootx64.efi. Format a pen drive to FAT32. Create /EFI/Boot folder on it and place this Bootx64.efi therein inside Boot folder. Now disconnect the HDD and see if it can boot to UEFI Shell from this pen drive. If it does, you are in fact in EFI mode.

Mouse driver is possible in UEFI but optional. Click BIOS (Again BIOS being a misnomer used by Motherboard manufactures!) is a selling point, not a must to have underlying Firmware confirm to the UEFI Specifications. With Hybrid EFI the only focus was ability to boot off > 2TB so only bare minimum EFI specs were confirmed to.
