17.10 w/o .1 is *toxic* (and anyway EoS, with .1 also). Already the first boot up changes the value. The UEFI is destroyed, so to speak. Btw., that would not have happened in CSM mode instead UEFI mode.

Hard cheese, inform in advance.

Installing a clean kernel in a live system has no effect because it doesn't allow you to boot.

You could try this:

1. Remove the HDD and connect temporary exclusive at another System!
2. Install Ubuntu 18.04.1 64 bit in UEFI mode!
3. Insert this HDD in the Lenovo G50-80 and try to boot! This should correct the false value.

As a thinkable alternative:

1. Remove the HDD and connect temporary exclusive at another System!
2. Install Win10 1804 64 bit in UEFI mode! (https://www.microsoft.com/en-us/software-download/windows10ISO - during the installation routine try "I don't have a product key"/"Ich habe keinen Produktschlüssel"!)
3. Copy the flashing tool with the current UEFI version to the harddisk (https://pcsupport.lenovo.com/de/en/products/LAPTOPS-AND-NETBOOKS/LENOVO-G-SERIES-LAPTOPS/G50-80/downloads/DS102231 - sadly old A0)!
3. Insert this HDD in the Lenovo G50-80 and try to boot!
4. Flash the current UEFI!
5. With a little bit luck the UEFI values will be set to defaults.
6. Now you could kill Windows with an Ubuntu 18.04.1 64 bit installation.

One more comment: Asking at https://forum.ubuntuusers.de/topic/corrupted-bios-due-to-intel-spi-bug-in-kernel-/ isn't the best idea.

And finally: Nail the 17.10-DVD to the wall!
