Hello Anthony, My situation is:
Lenovo Ideapad Flex 10. Came with windows 8 installed and updated to windows 10. I then installed Ubuntu 14.04 as dual boot and had each release of Ubuntu updated since 14.04. I was dual booting using legacy for Ubuntu and UEFI for occasional access to windows 10. Only recent change has been upgrade to version 17.10. I can no longer save changes to the boot order in the BIOS. I cannot therefore boot from USB and am not able to boot into windows. I can boot into 17.10. The trigger for this problem arising was clearly the upgrade from 17.04 to 17.10. I also have a Lenovo G710 with Xubuntu installed and no other OS. It is booting using "Legacy". I have also upgraded this from 17.04 to 17.10 and do not have a problem with the BIOS on this laptop. I live in Cologne, Germany but work away in Mainz-Kastel, Germany during the week. My telephone number is 00491713568623.

We have been working with Lenovo in China at full speed since last week to find out the root cause. Meanwhile, if you hit this issue, please send me an email at anthony.w...@canonical.com with your laptop's model name and the city where you live, optionally you can leave your phone number so that Lenovo can call you back if they need more information. It will also be very helpful if you can also provide a brief description of what you did (e.g. upgrade from 17.04 to 17.10, or fresh install 17.10, etc).

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.
