I have been using ubuntu 16.04 alongside windows 10 for 2 year and its running okay. Then i want to upgrade my ubuntu to 18.04 (still dual boot with win10). I upgraded from 16.04 to 18.04 using "reinstall using upgrade". After installation, my laptop didn't enter grub menu and loop over and over time.
I try to using boot repair (GUI ver), after finished and reboot again, it didn't change anything. Then i'm using terminal with this tutorial https://howtoubuntu.org/how-to-repai...ubuntu-live-cd, still didn't change anything.
Btw, i got this http://paste.ubuntu.com/p/WMw8D3x7hn/ after boot-repair finished. I'd appreciate any helps from this community.
