1 year ago According to WIM file format: https://download.microsoft.com/download/f/e/f/fefdc36e-392d-4678-9e4e-771ffa2692ab/windows%20imaging%20file%20format.rtf
One WIM file has one WIM Header, and has only one dwBootIndex.
So if you put 2 indexes in a single boot.wim file, I think only 1 is bootable, and another is not bootable.

What happened?
Can I make 2 editions of WinPE, one light/quick and one full, and put the 2 indexes in a single boot.wim, giving the user the option to start which one he likes, while taking the advantage of having partially identical indexes compressed together to save space ?
I've already added the 2nd boot.wim with this command:
dism /append-image /imagefile:E:\boot.wim /capturedir:E:\anotherBootWim /Name:"Older win11 boot.wim" /description:"Older win11 boot.wim"
