I use linux Ubuntu via a 32GB USB. Everytime I boot it, it doesn't save my data. Therefore, I found that I can create a live persistence key which I did with the help of this website: https://www.howtogeek.com/howto/14912/create-a-persistent-bootable-ubuntu-usb-flash-drive/ Which I did but doesn't save my data. Notes: I dont want to install linux on my computer.
Thank you for your help.
