  2. Second: Can't boot from USB I have a Ubuntu bootable USB and it work on other laptops but not on my system. My laptop just can boot from DVDs
  3. And third: Ubnutu boot faild Smiley Sad After reinstalling Ubuntu 17.10 .. whenever I turn on my laptop a blue dialog in a blank screen comes up and sys that "ubuntu boot faild"

Now .. Please help me to  fix this problems

I don't want to buy a new laptop because I love akampad (Ideapad Z50-70)

Re: BIOS Settings don't Save after Laptop Restart

Me too,


After installing ubuntu 17.10 and fiddling with secure boot so I could install third-party drivers it turned into a mess.


Nothing boots (cd,usb) and i've tried both mbr legacy devices and uefi gpt ones. Nothing.


Plus, every time I change anything in the bios, they get reset and the cycle continues, 


Secure boot always reverts to disabled and legacy option resets to uefi only


Reset to default has no effect whatsoever.
