Nero isn't free
I did try that EaseUs thing, but on startup it wanted me to insert a floppy into drive A, so that fell through.
I asked about DVD because that's what I have, I'm a college student. I'll be a millionaire soon enough, but I'm still working on it, that's why I ask for freeware and DVD stuff. The only huge file I'll be backing up is my disk's ISO, so multiple DVDs are no problem, I just need to know if there's anything I should know about that before I try it. Although, I do have an external drive on my Christmas list, so we'll see what becomes of that.
Either way, I still don't know how to make an ISO (or some other universal format) for free. I know I could do a files and settings transfer, but that doesn't get everything and I want this to be as simple as possible.
