Dual boot Linux boots into maintenance mode after Windows update

  • 772

GRUB boots my dual boot Linux/Windows desktop into Linux by default.

Today I did the Windows 10 October 2019 update.

Although Windows left GRUB unmolested, the GNOME display manager failed and Linux booted into emergency mode.

Any suggestions on how to troubleshoot this?

I am running Ubuntu 18.04 which I updated today before updating Windows.

boot dual-boot windows-10

    I finally solved the issue myself.

    When Windows does the Oct 2019 update it changes the block ID of the Windows partition!!

    So the Windows block ID in /etc/fstab must be updated!!

    SOLUTION:

    1. From linux command line type 'blkid' and note the block ID for the Windows partition
    2. Edit /etc/fstab and replace the old Windows block ID with the new block ID
    3. reboot
