I just installed Ubuntu 17.10 on my Lenovo G50-80, and after intallation I restarted and didn't see grub, so I wasn't able to load Windows, I tried Boot Repair and it said that I wasn't on a EFI session or something... I went to the BIOS, changed it back to UEFI, saved, booted, .... still the same problem. Back to BIOS and I don't see any of the changes I made! I even have an Admin password on the BIOS, I removed the password so to access BIOS directly, save BIOS settings, restart... and admin password is asked again. I found this thread and I find it very disturbing that Ubuntu is doing this to my machine, very distrubing and upset. Does anyone knows what's causing this?

It's not possible to save new settings in BIOS anymore and after rebooting, the system starts with the old settings. Moreover (and most important) USB booting is not possible anymore since USB is not recognized. It's very serious, since our machines do not have a CDROM. Lenovo forums at the moment are full of topics regading this issue.
