I would like to install Ubuntu 14 on my new HP Probook 450 G2 with windows 7. At the step "Installation Type", I don't have the choice "Install Ubuntu alongside Windows 7". I looked at the choice "something else" but I don't understand well what to do.
When I try Ubuntu on my USB live it works well. And the hard drive is divided like this: sda1 : system sda2 : HP recovery sda3 : HP tools.
Do you know why I don't have the choice "Install Ubuntu alongside Windows 7" and how to do a not too comlicated installation? Moreover do you know any problem with this model of computer or this brand?
Thanks
Marcel
