I stopped using Ubuntu after its installer failed on me, removing all partitions. Unprompted. EDIT: I remember I got up to enabling third-party drivers before partitioning, it was behaving weirdly so I went back, then it crashed and I restarted to see no partitions. I don't remember the details but my thing is I'm sure it was before partitoning.
