I know 32-Bit 'Win_8.1_U1' can only be installed into x86-architecture based UEFI firmware/system and 64-Bit 'Win_8.1_U1' can only be installed into x64-architecture based UEFI firmware/system.
But why ?
I think there should be some special UEFI files within EFI folder, 'boot.wim' and 'install.wim' which allow a UEFI firmware (x86/x64) to detect their respective OS (x86/x64). And if UEFI firmware (x86/x64) found their respective UEFI files (x86/x64) in EFI folder, 'boot.wim' and 'install.wim' , then it allow their respective OS (x86/x64) to boot and install in UEFI mode.
So I want to know about these Special UEFI files which are read by UEFI firmware (x86/x64) within from EFI folder, 'boot.wim' and 'install.wim' in order to boot and installation of their respective OS (x86/x64).
I want to put all Special UEFI files (both x86 and x64) of both OS (x86 and x64) into the 'Win_8.1_U1_x86.iso' so that x86 UEFI firmware treat 'Win_8.1_U1_x86.iso' as a x86 OS while x64 UEFI firmware treat 'Win_8.1_U1_x86.iso' as x64 OS.
So that I can boot and install 'Win_8.1_U1_x86.iso' in both x86 and x64 UEFI architecture based PCs without changing BIOS settings to 'BIOS/MBR/CSM mode' and 'Disable Secure Mode'.
Note- AFAIK, We can also install WINDOWS within from a WinPE 5.1 with the help of 'WinNTSetup v.3.6.1'.
'Win8.1U1SE_x64_boot.wim' is a unique WinPE which can boot into both BIOS and UEFI mode.
'WinNTSetup v.3.6.1' require only 'install.wim' for Windows Installation and can Install 'Win 8.1 U1' in both BIOS and UEFI based PC. It means 'install.wim' also contains some special UEFI files which extract into the Installation Drive during installation and play an important role when System boot from the Installation Drive in UEFI mode.
So can anybody please tell me about the Special UEFI files (both x86 and x64) in EFI folder, 'boot.wim' and 'install.wim' which allow a OS (x86/x64) to boot and install into their respective UEFI firmware (x86/x64) based PCs.
I know my thinking may be foolish, stupid and non-sense. But I want to know about the actual secret about the whole drama.
Any related information will be highly appreciated......
Thanks in Advance
