hi
really there is a solution for dual boot on tbook air netbook
distro antergos
on bios page set secureboot disable
delete all keys (going to setup mode) save and exit
start install antergos from bios page (boot override)
delete old boot/efi partition and create new sise 768 mb with antergos install driver
finish installation and reboot
open terminal
use refind (there are instructions on web)
copy usr/share/refind at boot/efi/EFI /boot
reboot
(before installation make usb stick fat32 going from bios to UEFIshell and copy EFI\Microsoft folder to usb and later after installation recopy from usb to EFI folder from shell for restart windows on refind menu selection)
basic steps
until it finishes installation
you need to block windows do not run them
it may take a second time to repeat all the steps
basic step delete old (boot\efi partition) and create new
*until refind install on Boot folder of boot\efi partition*
if all good…… make a copy on usb stick the folder EFI boot\efi partition with UEFIshell
for future (not need repeat installation) just copy the folder EFI from usb stick.
i hope help because this netbook with so stranger bios
elaborate and multi-hour procedures for solution
dont try selection linux on bios page because bios hang…. and then …….
