I'm kinda new in this and just installed ubuntu 16.04. Before this on the HDD was Windows 10. I put flash drive with Ubuntu and just erased/format whole drive and installed ubuntu.
Now when I switch on this laptop is asking me to choose to start ubuntu or make some memory test.. OS doesn't start right away until I choose something. Is it possible to hide this menu option at boot?
Secondly when I run fdisk -l
I see something strange that I don't know what exactly mean..

I don't recognize this:

I don't know why is there since I formatted whole HDD
What is this error means?
Partition 2 does not start on physical sector boundary.
