Hi. just got my hands on a dell 9550. I want to try and install linux on it but i want to first of all copy the hdd and save it. that is, all partitions etc etc so that if i mess up or once i am done, i could get all of it back. i dont mind getting software if needed and can even buy specific hdd for it. i have a 512gb ssd on the 9550. thanks for your help
