Comment 566 for bug 1734147

I fixed my laptop Acer E5-511-C5QS, it has all the described issues BIOS save won't change and i was unable to boot from a Liveusb, so i follow #554 and i use bruteforce procedure drescribed in #560 and find that my partition was (hd0,9) equivalent to sda9, i get stuck in initramfs, and i use #562 but instead of 'lsblk' i used 'fsck /dev/sda9' (where sda9 is your ubuntu 17.10 partition) then i answered yes ('Y' key) to all requests, when process finished i reboot my laptop and i was able to boot previous installed ubuntu 17.10, then i follow the description fix and that repair my BIOS, i hope this can help someone with the same problem.
P.d. sorry for my bad english.
