1st best try sd card … There install script for EndeavourOS DE’s + useful tools . You need install Base arch 1st .
here will help " [ARM] Install EndeavourOS on a Pinebook Pro Part 1 "
or you use from here . " https://wiki.pine64.org/wiki/Pinebook_Pro_Software_Release#Arch_Linux "
if you no sure or no confident do manual install you can try Manjaro . That another distro ( 
) + that have simple new user installer . It heavy ( my opinion) but ok if you no use Arch before .
hope this help
Edit. " but it complicated " Maybe! but you learn more than use install script . It help you understand what go on + help when thing go wrong ( which they will 
) .
