I'm new here and I really need a help. I have the same problem with almost any distro. I'm Bosnian, so I'm sorry for my bad English.
I have the problem when I want to install the OpenSuse (I'm tried also with Ubuntu, mint). It starts normally but when I come to the "Disk" step then occurs the problem. I can't see partitions. Also I have same problem with the Ubuntu, it doesn't see my disk. I have a windows 7 installed.
I have taken some snapshots.
