I'm now able to boot from my USB. The kernel update thankfully resolved this issue.
Booting into GRUB, entering the command line and typing "exit" seems to have worked for me. Of course, this was after I installed Kernel 4.14.9. Thank you all for the help! ** Description changed: 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. --- Affected Machines: Lenovo B40-70 Lenovo B50-70 Lenovo B50-80 Lenovo Flex-3 Lenovo Flex-10 Lenovo G40-30 Lenovo G50-30 Lenovo G50-70 Lenovo G50-80 Lenovo S20-30 Lenovo U31-70 Lenovo Y50-70 Lenovo Y70-70 Lenovo Yoga Thinkpad (20C0) Lenovo Yoga 2 11" - 20332 Lenovo Z50-70 Lenovo Z51-70 Lenovo ideapad 100-15IBY Acer Aspire E5-771G Acer Aspire ES1-111M-C1LE (not fixed by 4.14.9 and 4.14.10) Acer TravelMate B113 - Acer Swift SF314-52 (Legacy works perfectly, but UEFI problems still persist) + Acer Swift SF314-52 (Fixed by 4.14.9) Toshiba Satellite S55T-B5233 Toshiba Satellite L50-B-1R7 Toshiba Satellite S50-B-13G Dell Inspiron 15-3531 (not fixed by 4.14.9) Mediacom Smartbook 14 Ultra M-SB14UC Acer Aspire E3-111-C0UM HP 14-r012la --- 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.
