I have installed Lubuntu on my netbook (Samsung N150, I used to have windows seven) and everything is working good when my bootable key is connected The problem is I can't start the netbook if the key is disconnected. In Disk Utiliy when I want to do "safe removal", I get an error message: An error occurred while performing and operation on "pny USB 2.0 FD (pny USB 2.0 USB FD): the device is busy.
In details there is: One or more partitions are busy on /dev/sdb.
When I installed Lubuntu I choose to install, not to try without install, so I don't understand why my netbook needs the bootable USB key!
If I start my computer without the key, it starts normally (I see the samsung's logo) and then, the screen stays dark with a little flashing line in the left corner. In the BIOS I put the HDD on first position.
So, I really don't understand what is happening, I need help!
