I've managed it to install Ubuntu 16.04 on my brand new, no OS laptop Lenovo. I did it using USB (made with Rufus software). It did not go frictionless, but finally ended up with the happy message "Installation was successfull, please reset the comp".
However, when I reset it, take out the USB, it displays "No operating system" message. The OS seem to be installed, but not accessible.
What could this be?
Before making te successful installation, I've struggeled with EFI/Legacy, partitions and GRUB, apparently solving the problems one by one. Obviously something was not configured well.
Ideas?
