Just out of interest do your parents use something that is Unix based? My parents run Debian on one machine and the HDD on my dads laptop is covered with bad sectors so i remastered Ubuntu with all the applications he needed and used an old version of Unetbootin (DD never worked) to tranfer the iso on to a very small partition and now it runs off the HDD in memory but any kind of persistent storage knocks the drive out lol. I got them in to it in 2011 and they say its better and easier than windows. Do your parents use nix?
