@Mathieu Trudel-Lapierre (cyphermox) @Dimitri John Ledkov (xnox) Hi, thank you for having a look.
To be more clear about this issue: I had Linux Mint before switching to Ubuntu 17.10 few days ago - no dual boot, just Ubuntu I can access BIOS (either via f12 or one-key recover mode) I can change all BIOS settings, but the issue is that when rebooting, the BIOS keeps the old settings so the machine keeps rebooting in safe- mode. Thus usb is not recognized. https://ibb.co/fHntcm (bios, boot menu) before installing Ubuntu 17.10, USB was present as third option under the sub-section Legacy. Now it's not recognized. I hope this make things clearer. The USB option is not present obviously even when pressing f12 at startup (for selecting the boot source) https://ibb.co/msfziR Ubuntu 17.10 is working properly for me, and within Ubuntu USB ports work properly.
