Combine x64 & x86 in one ISO?

Does Windows 10 allow Duel Boot?     
I copied the Multi-WIM into Win10PESE and it copied all files
but didn't duel boot. Checked the bcd and everything look fine.

Explain "It did not dual boot"
You can only boot one OS at a time...   

Your should of been able the press F12 to get into your Boot Manager and then from there select UEFI USB or Legacy USB boot
then it should display the Boot Menu Options..
One UEFI option
Two legacy Options

I am trying to duel boot Win10PESE, not Windows 10

I am using Version : 10.0.10240.16384
10240.16384.150709-1700.TH1_CLIENTENTERPRISEEVAL_OEMRET_X64FRE_EN-US.ISO
My host computer is Windows 10 64 bit

I copied the Multi-WIM script into Win10PESE and it copied all files
but didn't duel boot. Checked the bcd and everything look fine.

Only trying to boot one OS at a time.
Worked great in Win8.1SE and Win8E SE.

Maybe you can post a pic of \Boot\BCD and  \efi\microsoft\boot\bcd

Hi Prz42.

Have you exported one boot.wim to another one (using imagex /export)? Because if you did it doesn't work. You need to copy the second boot.wim to another folder.  Ex: /sources/boot2/boot.wim

And you need to edit bcd file including a new entry, setting the path and a name/description.

I copied the Multi-WIM script plugin into Win10PESE and it copied all files

Well,
As written on FAQ

Q: Where to find project specific plugins ?
A:
As princaple we %99 put project specific plugins to projects 
.....

The only reason for not including these specific Plugins on new projects,
    They are not tested or they are not ready..


If you put a Special Plugin that does not exists inside distribution by only copying from other project,
Don't expect them to work out of box 

 and if they do not work, it is expected. 

Further, next post....

This remind me old idea, up to ChrisR :

on "Create ISO"
a checkbox saying=Exclude 'Run From CD'
with tooltip="Excludes 'Programs' folder and 'CdUsb.Y' file"

This is a *General solution for "Multi Architecture" and "Multi Project" scenarios (limit is the sky),
 sharing same "Programs"...

Further is up to end user getting "ufd" bootable or "iso bootable" by adding all results ;)

ps:
Chris, please move Programs and CdUsb.Y back forth via \ISO\TargetImage (or \ISO\TargetImage\RunFromRam or ...)

Since TargetImage folder is already junctionable for speed via plugin, no need another folder ;)
 and on my side, no need to work on Junction plugin 

To get the Classic Boot Loader
bcdedit /store "xxxx\Boot\bcd" /set {default} bootmenupolicy legacy
bcdedit /store "xxxx\efi\microsoft\boot\bcd" /set {default} bootmenupolicy legacy



I added bootmenupolicy legacy also for Win10 in PostConfig plugin on server 

(limit is the sky),

I believe I can fly I believe we can touch the sky

I had enabled > bootmenupolicy legacy < just to get the "Windows is loading" bar

I believe I can fly I believe we can touch the sky
I think about it every night and day
Spread my wings and fly away

listening now....


What do you think about CreateISO checkbox idea 

I'm not there the next days, to mature 
In Multi-Wim there is already (more or less manual):
"Copy programs folder from previous build with another source-architecture"
"Copy folder with programs from previous build they are disabled in the master build" with do not overwrite existing files.

See you,

I'm not there the next days, to mature 

I verrrry fully understand you. 

Maybe you can post a pic of \Boot\BCD and  \efi\microsoft\boot\bcd

Pic from Boot\BCD

It didn't create a efi BCD, but my computer doesn't use efi.
