problematic installation + booting problems

[arda51616]

Hello,
I bought and ideapad 320 and installed ubuntu on it. It got a problem on the installation process and now when I boot up I get the grub 2.02 screen. I have tried to get into bios and switched off legacy support and have done the initial installation through a usb. What would you recommend me to do, /boot says I need a kernel first and fellow user recommended me to reinstall but I cannot do the reinstallation process?

Are you trying to dual boot? Did you turn off fast boot? What version are you trying to install?
