Blinking cursor and very clean and black screen on Linux
fi flag

I have a screen like this, I guess it is caused by running out of disk space.

I tried so many solutions and none is worked, tried to boot to windows 10 and get access to Linux files and delete them and did not work, also I tried to use rescue kali and did not work.

Is there any way to fix this?

How do I tell the Ubuntu bootloader to boot from a different drive?
cn flag

This should be a simple question. My system is set to dual boot Ubuntu 20.04 and Windows 10.

The HDD is only 5400 RPM and the slow low load time was a constant source of aggravation.

I just purchased a new 2TB SSD and would like to ha ...
