Is there a command line switch for making an image bootable?

[MusashiOf5Rings]

I've read the Readme file half a dozen times, gone over every switch, googled this, and read a dozen forum posts here.  I've also tried /MAKEIMAGEBOOTABLE YES, /MAKEBOOTABLE YES, /BOOTABLE YES, /MAKEIMAGEBOOTABLE 1, /MAKEIMAGEBOOTABLE, and I'm at a loss. Everything works, but the application will prompt me if I would like to make the image bootable and I would like to get rid of that prompt.

I'm typing the following:

"C:\Program Files (x86)\ImgBurn\ImgBurn.exe" /MODE BUILD /BUILDOUTPUTMODE IMAGEFILE /SRC "C:\Win10iso\Windows10\" /DEST "C:\Win10iso\Windows10.iso" /VOLUMELABEL "Windows10" /OVERWRITE YES /START /CLOSESUCCESS /INCLUDEHIDDENFILES YES /INCLUDESYSTEMFILES YES /MAKEIMAGEBOOTABLE /BOOTEMUTYPE 0 /BOOTPLATFORMID 3 /BOOTIMAGE "C:\Win10iso\Windows10\efi\microsoft\boot\efisys.bin" /BOOTDEVELOPERID "Microsoft Corporation" /BOOTLOADSEGMENT 07C0 /BOOTSECTORSTOLOAD 1

Screenshot the actual prompt you're seeing please.

There is no 'MAKEIMAGEBOOTABLE' parameter, the 'checking' of the 'Make Image Bootable' checkbox is controlled by the existence of a valid value for /BOOTEMUTYPE.
