Universal Dual Boot BIOS/UEFI for Windows 7 / 8.1 / 10 AIOs

However I forgot to mention I want the AIOs separated by version, not all versions in one.

All In One what ??

USB or WIM ??

I am talking USB - formatted FAT32 to support UEFI Booting

Separated versions, i.e., one AIO for Windows 7, another one for Windows 8.1, etc. Don't want to mix Windows versions.
 
Then the AIO has to be compiled in an iso file, ready to be burned onto a DVD (single or dual layer, size don't matter) and ready to be deployed by Rufus onto a USB drive (Rufus is a neat program that I know can deal with M$ isos).

The install.wim files within each source folders on each architecture folder (x86/x64) are already serviced with offline integrated updates AND multi-index (multi-editions).

Edit: I'm going to make right now a short video about one first issue I've encountered while compiling a Windows 7 AIO with double architecture folder...

Edit 2: Here's the video:

easy enough..

use your standard boot files
and create Version folders for your AIO wim's since they are already multi-arch

My standard boot files? You mean to say my modified bcd files?
Hmm, my install.wim files aren't multi-arch they are multi-edition. Architectures are separated in two install.wim files.

Did you see the video?

I really don't get why the driver problem as shown in the video. Boot.wim file has integrated mass storage drivers besides this is a test under VMware so I don't get it, sigh.
Moreover, this files work correctly when crafting a single architecture AIO.

What about USB? Do you use three different USB disks, do you like to add all windows versions to one USB disk?
 

a Windows 7 AIO with double architecture folder...

Windows 7 setup.exe dosn't support x86/x64 folder.
Windows 8 and up setup.exe does support x86/x64 folder.

Hi man,

I have your problem too. I watched your video.

Did you find any solution?

I used windows 10 files but get same errors. It seems that because windows 8.1 Update 3 and Windows 7 SP1 doesn't support multi architecture files x86 and x64 folders.

I'm pretty sure, because windows 10 media creation tool use this bu windows 8 media creation tool doesn't support this. It has no option to select both architecture.

What's your opinion?

REgards.

You need to create a BOOT.WIM for every OS and ARCH
Then update your BCD files on the Builder USB..
Place the WIM file in separate SUB Folders...

SOURCES
Win7-64 > Boot.wim
Win7-32 > Boot.wim
Win8-64 > Boot.wim
Win8-32 > Boot.wim
Win10-64 > Boot.wim
Win10-32 > Boot.wim

You must use the original BOOT FILES from Windows 8 or better to support Multi-Arch booting of windows 7
