Thanks, As much as i do want to use Ubuntu and i could use it, i feel very familiar with windows and its much easier and less of a learning curve just to move funds to HW wallet. allthough i still see a security risk on the offline pc if im throwing in a usb, im gonna try the photo methods for the qr codes and see how it goes once setup.
Installing ''fresh'' wind0ws usually means it's either illegal risky copy or not activated copy..
You are not going to use this computer for any science or heavy design work, so there is almost no learning curve with most Linux OS.
Something like Linux Mint is better than Ubuntu and looks similar like wind0s, and there are other distros that are even more similar.
You can also just use TailsOS that can work on USB drive.
