Comment 22 for bug 238789

Because what you describe are multiple issues that seem unrelated to one-another, e.g. unbootable kernel, microphone settings, programs disappearing from the menu, limited user-account priviledges...

Your problem seems a support problem (that's what the forums are for) and not a bug in Ubuntu.

By the way, for help using Clonezilla, you can read this:
