I'm actually running dual boot with Chrome OS. I guess there's probably an easier way to access this partition from the Chrome OS?

oh, well that explains why you're not able to boot the lubuntu USB - certain bootloaders don't work well with the stock firmware, and often you need additional kernel parameters to boot Linux

to mount the partition in ChromeOS, open a shell terminal like you would to open the script, then:

Code:

mkdir /tmp/storage
sudo mount /dev/sda7 /tmp/storage
rm /tmp/storage/.kodi/userdata/advancedsettings.xml

then reboot into OE and try again. You could edit the file from ChromeOS vs deleting it, but if you don't know how to use vi, it's better you don't.
