I have an EFI only tablet and I want to be able to boot into dos. I don't want to use vmware or virtual box. How can I install grub2 efi into usb flash drive and after that how can I add a dos to it?

AFAIK, DOS requires BIOS to boot, so it's not possible to do what you want unless the EFI has a Compatibility Support Module (CSM) to provide BIOS compatibility. My understanding is that most EFI-based tablets lack CSMs. Thus, chances are your only way of running DOS on your tablet is via a vritualization tool like VMWare or VirtualBox. – Rod Smith – 2017-07-18T16:58:55.620
