The first thing I would try would be to run fsck -C -f on all the
partitions that were mounted at the time of the crash.  Partitions
sometimes will not mount because of uncorrected errors, and being
unable to mount would probably stop booting as well.  You may need to
boot from a live CD/USB to do that.

That paste file looks like a Kodi log file, not anything from Boot
Repair.  Did you upload the right file?
