lenovoZ570, i7 x64,8GB, 700GB, Nvidia Optimus+intel, 1366x768, win7+11.10 ubuntu+kubuntu. Until now nvidia isn´t installed or used. Some problems, which may relay one on another or interact:
+ after running startup to configure grub2 strange things happen during boot or at shutdown + startup loaded 19MB but nearly nothing is to change. I choose ubuntu 30015, it is shown on the button but at boot only the cursor is on old recovery 30014 + 14 entries in grub, 6 ubuntu(30012,30014,30015) 4kubuntu(30014,30015) 2win7 and 2 mem
So the question: Is it possible to remove that useless "startup" without blackout? It changed more than 25 places.
