I have an Acer ES 15 laptop in a dual boot setup, Windows 10 and Linux Mint 19.1. I installed the October 2018 update a few days ago, and it destroyed my ability to boot to Linux, going directly into Windows without giving me the choice to boot to Linux. I booted to my Linux Mint live CD and found that the Linux partition is still intact with all files visible, but no boot capability. I downloaded and ran the grub boot repair utility from within the live CD environment, it completed successfully and said the grub file was repaired, but still no boot to Linux. Will I have to wipe the Linux partition clean and do a reinstall to restore my Linux bootup option? Or is there any other option to save my current installation and regain access?
