Windows 10: Unable to boot to Windows not even from USB drive

Hi, the other day I was greeted with blue screen that "a required device is not connected" and the PC wont boot. I tried EasyBCD but it did not work and stuck on some ATA error loop.
But after that I got a new blue screen and this time "The Boot Configuration Data file doesnt contain valid information for an operating system".
File: \Boot\BCD
Error Code: 0xc0000098

Now the problem is i am trying to boot my computer to attempt some repair but its not showing me anything even I am booting from the bootable USB drive created in Rufus. I have also tried setting priority to USB in boot sequence but in vain. What can I do, i am not even able to format and install an operating system. Set aside the question of repairing. PLEASE HELP !!

Note: This is the third time I am getting this kind of problem in one year of my purchase of new PC. I have UEFI BIOS and I dont know may be thats the culprit behind all this. All the three times my BIOS settings was default and PC was working fine but one 'fine' day everything suddenly changes and everytime I had almost the same kind of problem.

PC Configuration
Windows 10 Pro
Intel Core i5 Skylake
Gigabyte H110 S2PH
Kingston Hyper X 8GB

Windows 10 Unmountable Boot Volume Error

created bootable USB drive but unable to boot from the same

 

Problem when trying to creat C and D partition (0x85b02c50)

This is a long-standing bug in Windows Setup, which MS doesn't seem to have the ability to fix even though every other major OS' installer gets it right. Let me just quote from

this well-written article that also has the solution:

This error is hardware-dependant and its appearance varies from PC to PC. It depends on your motherboard, your USB interface, the USB stick you are using, and the version of Windows you are installing.

During setup, Windows must identify which drive is your primary boot drive in order to correctly configure the MBR and bootloader. This error does not normally apply to EFI and UEFI installations of Windows 7, Windows 8, or Windows
10. You can read everything there is to know about the MBR configuration and boot process here.

Depending on how your PC is configured and which hardware you are using, Windows setup can sometimes be unable to tell which drive is an external USB drive and which drive is a local disk that Windows should be installed to. This
especially happens when using larger USB drives to install Windows or if you have configured your BIOS to boot from the USB drive first always. Also, some USB sticks present themselves to Microsoft Windows as a regular drive instead of identifying as a bootable
USB.

If Windows setup cannot reliably determine which is the boot drive, this error will appear.

Just follow
Fix #1 (eject and reinsert the USB drive), then delete both partitions shown in your screenshot above and install Win10 to the completely empty drive.

 

Does the USB flash drive have a FAT32 partition on it, or an NTFS partition on it? To boot a USB flash drive on an UEFI computer, it has to be FAT32.

 

Yes the computer is UEFI but it is disabled in the BIOS. Earlier I created a bootable USB using NTFS partition and installed the drive. And yesterday only when the computer was corrupted, it was booting but now its not.
Screenshot attached.

 

I have downloaded WinPe X64 and burned the image using Rufus (NTFS-UEFI/CSM mode). Now when i boot my PC it shows the Windows 10 logo and then heads up to command prompt. What commands do I have to enter here?

 

diskpart
list disk

Are all your drives shown in the result?

 

Yes the hard disk shows there and online as well, but neither its marked Dyn nor Gpt (I mean star) and it also says the free space is the same as the size. One thing i would like to mention that when i select the disk, sometimes it selects sometime it does not. And also when i enter list volume command after selecting disk, its shows only the USB drive. Screenshot attached. (Using WinPe 10)
