Lenovo ideapad 330 (15ARR) ubuntu issues and their solutions

Issue-1: None of the ubuntu distros are getting installed

Solution: Ubuntu distros lower than 18.10 will not work in this laptop, as minimum kernal version required is 4.18.

So install ubuntu 18.10 / xubuntu 18.10 / lubuntu 18.10 / kubuntu 18.10 in UEFI mode

Issue-2: Wifi is not working
