If your hard drive is still readable you could clone the first partition ID, create rEFInd system on it and then from there install any other type of systems you like.
Alternative repair method is to resolder the NVRAM chip and copy the BIOS content from the old one to the new.
Powodzenia!

Re: y50-70 BIOS can't save settings - and I can't boot system instalation from USB/CD

hi all i have solve my problem on my lenovo y50-70 by this post

https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1734147

 

by use this instruction in the post

Fix: The issue was fixed in kernel version 4.13.0-21 by configuring the kernel so it is not compiled with Intel SPI support. But previous affected machines still suffered from a broken BIOS.

Repair: If you still can boot into Ubuntu, you can recover your BIOS with the following steps:

1. Boot into Ubuntu
2. Download http://people.canonical.com/~ypwong/lp1734147/linux-image-4.15.0-041500rc6-generic_4.15.0-041500rc6....
3. Install the downloaded package:
  $ sudo dpkg -i linux-image-4.15.0-041500rc6-generic_4.15.0-041500rc6.201712312330+20170103+1_amd64.deb
4. Make sure the kernel is installed without any error. Once installed, reboot.
5. At grub, choose the newly installed kernel. You can choose the "recovery" mode.
6. Reboot and go to BIOS settings to confirm your BIOS has been recovered.
7. In case your BIOS is not recovered, reboot to the new kernel, then reboot *once again* to the new kernel, do not enter BIOS settings before the reboot. After the second reboot, check BIOS.
8. If your BIOS issue remains, download another kernel from http://people.canonical.com/~ypwong/lp1734147/linux-image-4.15.0-041500rc6-generic_4.15.0-041500rc6...., and use dpkg to install it, then repeat steps 4 to 6.

After your BIOS is fixed, the kernel packages you just installed are no longer needed, you can remove it by running 'sudo dpkg -r linux-image-4.15.0-041500rc6-generic'.

The patch used to build the linux v4.15 kernel in step 8 can be found at https://goo.gl/xUKJFR.

---

Test Case: Fix has been verified by our HWE team on affected hardware.

Regression Potential: Minimal, it's unlikely anyone is actually doing anything which requires this driver.

Did this happen after installing UBUNTU 17.10 or any of it's derivatives?

If so, there is a fix.
