Hi Prerak, This is Ramesh.
You can create an EFI partition on Disk 1 using these steps.
From admin Command Prompt, run:
diskpart
select disk 1
create partition efi
format fs=fat32 quick
assign letter=Y
list vol
exit
bcdboot C:\Windows /s Y: /f UEFI
Post the output.
Note: If a command fails to run correctly, please post the error message here and don't continue further.
