Ubuntu 18 and Windows are installed as dual boot on my Acer Aspire F15 laptop.
Since today my PC freezes completely when restarting, approximately 20 seconds after the grub screen to choose OS, typically at the login page. The same happens when booting to Windows or to Ubuntu from a live USB session.
However, it does NOT freeze when booting to Ubuntu in recovery mode.
Any idea what can cause such a freeze and how to solve it ?
My guess is that it's hardware related as it also freezes on Windows, but why is it not freezing in Ubuntu recovery mode ? Is recovery mode using less hardware ?
