I have tryd to install win7 on virtualbox. I get this erorr: and the error message said that i need to do in terminal: then i searched over the net for solution and i found some commands. At some point it asked me if i whant to overwrite some files and i selected "yes". Now when I start my laptop I get this: The first line is the same as the second but without "recovery mod". And when I select the first options it starts the OS with no problem. But I don`t want this screen to show of. After that I still had the same problem with virtualbox. I restarted it was the same. Then I used again: And then restarted. Then virtual box was OK. But this screen on start still appears. How can I fix this? Thanks!
