I've got my Acer Aspire One 722-C6Ckk from the official servise centre. They installed Linpus on it. I was trying to install Linux (Mate, Ubuntu, oldest and newest versions (https://help.ubuntu.com/community/AspireOne)) and Windows XP, making bootable USB-stick with Unebootin. But in all cases download just doesn't start: black screen with cursor appears. What am I doing wrong?
