@Collin, And I also verify by 4$'s comment in #13, I can see every menu entry of grub with the suffix 'from recovery partition'.
Might be the original issue is fixed. But from the title, the issue from DVD image also caused by the partition which has .disk, so should I open a new one for the issue which boot up from DVD?
