This live version of PureOS should work with EFI:
Thank you.
This work to boot from USB.
I had problem with my wifi system not detect the hardware for “Intel Wireless 8265 / 8275”,
so I think I will wait for stable release and try again.
My laptop is ASUS-vivobook S15 s532fa
thaiiceland.is
that is likely an issue with proprietary drivers being required for the wifi card you use.
Thank you. Just if mater I want to provide more info.
booted in Linux-mint, this is the output from lshw -c network:
lshw -c network

(I made a star around where it differs)
I hope to find a solution, but meanwhile I can just do some text-editing or something. It is nice distro. If I don’t find solution, maybe it will in stable release??
But thank you very much.
Well… after lot of source I found the solution.
Intel WiFi driver requires a non-free binary blob (https://www.cyberciti.biz/faq/intel-wifi-on-debian-linux-when-you-get-firmware-failed-to-load-iwlwifi-8265-36-error/)
Because I didn’t have any internet-connection I was not able to do what said on this web, so I kept search and found https://forums.debian.net//viewtopic.php?t=137865
I did downloading the iwlwifi-8265-36.ucode file from https://github.com/intel/opa-firmware on my Linux-Mint, and then I reboot into PureOs and copy the iwlwifi-8265-36.ucode file to /lib/firmware/ folder.
Then in terminal
sudo lshw -c network
but nothing seems to change.
Then
$ sudo modprobe -r iwlwifi
$ sudo modprobe iwlwifi
and then I saw some change and wifi dewice start working.
Now I am typing this from my PureOS system 
Thanks for all and hope this info can help others…
I noticed that in /usr/share/backgrounds/pureos/ is an xml file that can change background images.
But if I want to select my own background change every few minutes, it seems I only can select image (not xml file).
But I can change the content of the pureos.xml and then I can have the background pictures changing every few minutes.
I did then make a python program to automatically create a xml file from a picture folder.
I decided to share the program with you if someone want to auto-create xml file from any picture folder.
To use it:
- extract the zip file and copy it to the parent folder of the images to use.
- open terminal in the same parent folder, and type:
python3 thaiiceland-xml-creator.py
and hit enter.
You will be asked for the name of the pictures folder, time in minutes for the background images and seconds in transaction while change images, and the name of the destination xml file.
Here is this, if someone is interested:
