  • type fsck -f /dev/sda5 at (initramfs) to attempt to repair the filesystem – bgregs Nov 9 '18 at 15:10

You need to attempt to repair the file system (the error message hints at this by saying):


This can be done by executing the following command at the (initramfs) prompt:

fsck -f /dev/sda5

This question originated because of recent Windows 10 updates (in a dual boot environment) flipping "fast-boot" back on. The problem was documented originally here: link

The OP had to disable fast-boot, and was then presented with the above error. The fsck command finally resolved their issues.
