After some problems with a Win8/Linux Mint 12 dual boot system I now have all working well with one minor problem in the Boot Menu.
I have TWO sets of entries for Mint. The first set (not shown below) is correct and works OK but the second which is unnecessary and refers to "sdd3" produces error messages. See this excerpt from grub.cfg:
This screenshot shows there is NO sdd3.
How can I remove these two menu items please?
