In brief: Some overlap

Most people have frequent "colds" which are usually caused by rhinovirus, adenoviruses and others small viruses - the body usually confines these to the upper respiratory tract and usually fights them off in 2-5 days.
Over 5-10 days the flu can spread down into the lungs, causes high fevers, muscle pain, joint pain and more rarely lead to severe pneumonia requiring ventilator support and death.

In brief: Cold vs flu symptoms

Flu symptoms may include fever, sore throat, cough, achiness all over, headache, chills, feeling tired, nasal congestion, nausea, vomiting or diarrhea.
Colds are usually much milder than the flu and often lead to a runny nose. Colds don’t usually lead to serious complications (i.e., pneumonia).
