My Lenovo G50-70 Laptop not saving BIOS, It's corrupted and I am unable to reboot it. What should I do?



When I installed Ubuntu 17.10 my Lenovo G50-70 BIOS Corrupted and Now it's not saving BIOS EFI to legacy.
Also, I am unable to use Ubuntu 17.10 Too.



Whenever I install Ubuntu 17.10, and after completion, it says please restart, I do it, but after that, it says Install Ubuntu or Try Ubuntu without Installing again and again.
If I remove My DVD, it says, EFI (PLDS CD/DVD......_) Not detected.



Also, it is accepting only my ubuntu 17.10 disk (PLDS CD/DVD.....).



Also, My BIOS Not showing Legacy options when I am trying to choose UEFI TO Legacy.



Should I try to re-write disk and try to install 16.04 LTS? Or what should I do next?



note: (bugs.launchpad.net/ubuntu/+source/linux/+bug/1734147 this link is not helpful for me, because I am only able to open my Laptop when I insert DVD and click on Install Ubuntu or Try Ubuntu) so, I am also unable to use UnetBootin too. There is nothing working. Please Help)

          Since the solution in the link isn't working, I guess the only solution is to flash the bios chip (after removing it and connecting a programmer to it).
