I agree with Thomas about the problems to boot some old computers.
I'm continuing to develop/tweak dus-iso2usb, added an extra (optional) parameter 'boot-flag' that can be added when mkusb partition table is selected. It helps HP computers, but may spoil booting some other computers.
So I think we probably need ways to get boot drive versions with and without a boot flag. One way would be two different iso files, another way is to use some special tool (like dus-iso2usb) for the corner cases that need a boot flag.
