Thanks for your comments, I am new to ARM installation, and never convert a Chromebook to Linux NoteBook, I am retired and doing that to my grand-kids…, I am more familiar with systems using Intel, AMD processor and a standard BIOS, my computer tower is a ‘Debian-Facile’, also called ‘DFlinux’.
1) To answer ‘Laibsch’, I planed to use Armbian Thinkerboard/s simply because it was the same RK3228 processor, and they are both mfg by Asus, and according to ‘NicoD’ Youtube video, Armbian-config let me easily install French version of Debian.
To answer ‘The Tall Man’
2) Archlinux is not my 1st choice, other class equipments, with school softwares are in Debian based distributions, and Archlinux has some differences in instructions, this is why I targeted a Debian based distribution to avoid futur problem
3) Currently for testing, I remove the ‘Write protection’ screw on the board, and in ‘Developer mode’, using and external USB, with CTL+U at start, is running Lubuntu 18.04, from Zutchi group image, but this version of Linux is old, and I failed to upgrade since Ubuntu no longer have 32 bits distribution.
4) I will try your suggestion using Armhf distribution from Debian (trixie) using EFI booter,
Let me few days, I have other thinks to do, and I don’t want ‘Brick’ the machine, I will read carufelly and try to install on eMMC of the C100P to avoid, for the kids using external device with CTL+U.
Thanks again for your time and your usefull comments
