2017-11-13, 7:59 AM
I am on Ubuntu 17.10 and could not find the file grubx64.efi but I do have grubx64.efi.signed

I have replaced this file with the refind_x64.efi but not change. Did I replace the correct file ? or ?

Re: Y50 70 BIOS Can't Save Settings Or Exit

I resolved!

I have a eprom programmer (Minipro TL866CS)..

I did'nt flash the original chip on the motherboard, but i bought a brand new chip (i had found an GD25Q64BISIG on ebay)

so i read the original eprom (the 3.03 that didn't save any change) and i saved the file (eprom303.bin).

Obviously, before I put out the bios chip with hot air...

After that, I programmed the new chip with the old data. I soldered the new chip on the motherboard ... and now it works! now save all change, now i can boot in legacy mode!!!

I didn't try to remove and solder the same chip..maybe this work too.

Sorry for my bad english... but i hope to help somebody to fix this problem

If your Linux is still working use the command:
efibootmgr -v
to see exactly, to what file the BIOS bootloader is hardcoded. Then replace that file with rEFInd dedicated.

Aborted. Press any key to exit._

 

So what to do now.

I think it is really absurd that some basic feature like dual-boot bricks a BIOS chip. Actually absurd part is it is a known issue and Lenovo doesn`t do anything about it. I had to send my PC to Hardware service to solve the issue. But I had to dual boot for my project and i think it accured again. Luckly this time I realized before losing both OS but still if I want to change OS it is not possible anymore, It makes me feel left alone by the company. I don`t know what we can do about it

It is not the dual boot but Ubuntu 17.10 causing the problem with Lenovo. Please follow this link and click "Yes, it affects me" so we can get the numbers up.

A simple fix can be provided by Lenovo Engineers is a bios recovery update using USB flash drive, but unfortunately this solution isn't even available for our laptop...
