I really need some ideas, here's my situation:
I formatted my SSD, my BIOS is in UEFI mode with secure boot enabled and i 
can't change any settings.
I can only boot from PXE over network ipv4 / ipv6.

I tried to install ubuntu on my SSD with another computer but an user
noticed me that EFI boot is looking for an UUID partition of ubuntu that
it changed after i formatted my drive.

So i thought that the solution was install successfully ubuntu on my SSD
in my stucked laptop and then through efibootmgr command i were able to
read which UUID i need to setup into the partition to make the OS
bootable.

Using AIOBOOT i'm able to boot grub2 and creating a bootable image of
ubuntu the installation begins but it stops for some reason (i think
uefi blocked the installation).

In this situation i don't know how to do a kernel update to fix the BIOS.
If anyone have a UEFI (with secure boot) compatible guide to boot and install 
linux please tell us, i think it's the only way to fix our laptops

Bug description:
  Description: An update to linux kernel on Ubuntu 17.10 that enabled
  the intel-spi-* drivers made Insyde BIOS unusable. Main issues were
  Settings being not stored, USB Boot impossible and EFI entries read-
  only.

  Fix: The issue was fixed in Kernel Version 4.13.0-21. But previous
  affected machines still suffered from a broken BIOS.

  Repair: Boot Linux and Install Kernel Version 4.14.9. Reboot into
  Linux and BIOS should be restored to a working state.

  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.

  Original Description:

  Basically on Lenovo Y50-70 after installing Ubuntu 17.10, many users
  reported a corrupted BIOS.

  It's not possible to save new settings in BIOS anymore and after
  rebooting, the system starts with the old settings.

  Moreover (and most important) USB booting is not possible anymore
  since USB is not recognized. It's very serious, since our machines do
  not have a CDROM.

  Lenovo forums at the moment are full of topics regading this issue.

  Thank you!!
