Fyde OS on a Nextbook tablet computer?

Hi, I just discovered the OS a week or two ago, and it rescued my older travel computer. I also have a tablet that is in great condition that just can’t handle Windows 10. It is a Nextbook, and because the keyboard is detachable it doesn’t have a Boot from USB option. It does have a native microSD slot. Does that seem like something that could work to put Fyde OS on this tablet? If not is there a way to install the OS on something without a USB boot option? Or is it all over my cheap-but-sturdy tablet?

Thanks in advance.
