I have dual booted Ubuntu 20.04 alongside Windows 10 this morning. Everything has been fine since installation, but now after restart I can't boot into Ubuntu and this is the error message I see: enter image description here

I am using HP bs-145tu laptop with Intel core-i5 8250U with 8GB RAM and no GPU.

How do I fix this problem?


rtw_pci indicates a realtek wifi adapter, which has a lot of compatibility issues with linux. I assume you have used a bootable USB stick for installation, and if so, open it and repair the disk using GParted or Disks. Then, Please check out this github repository for the appropriate drivers needed, as I guess these might be causing the problem.

I had multiple python versions installed and when trying to retain only one and remove all the remaining versions, I broke the system. And learned this the hard way that python is a dependency for lot of apps and even system too. So, in recovery mode, I did:

sudo apt-get install --reinstall ubuntu-desktop

and then:


Then I had no problems booting into Ubuntu.
