I have problems with Bios after upgraded to 17.10 on DELL Inspiron 5551 1- NO UEFI boot and can't boot from usb Ubuntu 14.04, 16.04, 17.04, 17.10, or Microsoft 8.1 all failed, also no hiren's boot can run from cd or usb only can run Ubuntu from CD on legacy choose
2- i tried to change settings to others or reset to default but always back to it's options after saving and restart, also it can save user password but no any others
3- i got HDD1 - Ubuntu drive or option instead the BIOS options, even after i removed my hard driver and CMOS battery , no saving changes and HDD-1 - Ubuntu option still there
NOTE: this bug number 3 Lenovo laptops reported about it with many versions of it as softpedia posted about that today, it seam like that
4- finally I got network failed and the report that want to access you is full with more missing files, even after i changed to Ubuntu 14.04 after update and while , the same happend, so i think it's from Bios, because it still working on try Ubuntu on CD
I found many other problems with it such as you can't access "'gksudo gedit /etc/default/grub" , Videos program missing more options and you can't remove it, battery went to 4 hours from 6 and it still like that on other versions of Ubuntu the BIOS went crazy, and more
But the main problem now is the BIOS and How i can fix it? i am trying about 3 or 4 days with many ways but no any fix
