What you need to boot a 64 bit ISO.
-EFI folder
-A grub.cfg tailored to you distro (only required for some including manjaro)
-64 bit Linux Distro ISO
-Some knowledge of the grub commandline, including how to boot .iso files using grub.
-If you are using manjaro, just follow this guide https://archived.forum.manjaro.org/t/tutorial-install-manjaro-on-a-32-bit-efi-64-bit-cpu-system/77361
The bootia32.efi, and i386-efi folders come from the Manjaro xfce 18.02 iso, and Jonathan Wells.
If you are using ubuntu, use http://www.jfwhome.com/2016/01/04/latest-steps-to-install-ubuntu-on-the-asus-t100ta/ as a guide
The grub files provided are out of date. I'd reccomend recompiling a new version via this guide! https://github.com/jfwells/linux-asus-t100ta/tree/master/boot
