Hello ! Trying to install linuxlite on HP4510s probook laptop. Using a live CD the installation runs well but rebooting the error message indicating indicating no disk no boot appears. It seems the bios is "locked" on these laptops. Tried several tips from various linux distributions but nothing worked. Linuxlite operates without a problem from the live cd and even on and usb bootable key but I can't make it run from the hard drive of the laptop. The old windows 7 OS installed on the machine was corrupted so had to eras it... so no OS as I cleaned the disk erasing it before the LL installation. Any solutions/procedures anyone? Thanks for your help....
