How did you actually install LL? Did you after booting go straight to installing LL or did you start LL first and then installed it from there? What options did it give you when installing. Did you wipe the harddrive in LL with partition drives before installing LL? I used the option delete in partition drives and then create new partition and format it to ext4. I have W10 and LL 4.2 install on one harddrive installed W10 first and then LL, used the something else option and did install from there.
