I have the same issue on my Lenovo Z50-70. Only just noticed, as have been running 17.10 since late beta and haven't needed to touch UEFI.
I've been running all manner of Linux distros on my systems for a decade and this is the first time anything has actually corrupted the hardware firmware (BIOS/UEFI). More fool me for installing a non LTS I suppose. I simply cannot afford to replace this machine at the moment, and from current reports it appears that come the next time I need to reinstall for any reason my laptop is, to all intents and purposes, bricked. Not amused.
