The only thing I'd say is this:

USB sticks are not the same thing as memory cards.

I've seen laptops where the card slot doesn't appear as a working
device except when there's a card in it. I am not sure I've ever seen
a card reader presented as a bootable device.

USB memory sticks, AKA pendrives or thumbdrives, appear to the PC as a
USB-connected hard disk. The firmware of all modern computers should
see that as a potentially bootable device -- depending on the contents
of the stick.

But a memory card might well not be, whatever is on it.

Some PCs might boot from an SD card but I don't think it's a safe bet.

I have got round this in the past using a tiny USB stick which is a
single-format SDHC card reader. It doesn't appear as a card reader to
the PC -- if you put a card in it then plug it in, it appears as a
thumbdrive. No card in it and it doesn't appear at all.

But I think you may be barking up the wrong tree trying to boot from a card.
