Explain the solution to the freeze when ubuntu dual system starts

Solution to ubuntu stuck when dual system starts (tested on ubuntu 16.04 and 18.04)

Problem Description:

After installing the ubuntu dual system, when I start the ubuntu system for the first time, I get stuck on the startup interface (or a black screen). This is probably due to the graphics card driver. The details are not explained here. The following methods can be successfully solved. According to me Personal experience, this may be the simplest and easiest to understand among many methods.

Solution:

1. (If it is stuck, it will be forced to shut down) Turn on;

2. (In the selection system interface) select ubuntu advanced option, press enter;

3. (In the two modes that appear) select the recovery mode and press Enter;

4. (Among the many options that appear) select grub and press Enter (you can see lines of code that seem to be awesome running past);

5. (After running the above code, you should be able to return to the interface of many options) Select resume and press Enter to enter the system.

In fact, you can enter the system every time you boot, but it is very troublesome, so let's make permanent modifications below (provided that you have entered the system through the above method):

**1. Modify the /etc/default/grub file: **

Terminal input: (This command needs to enter the user password to confirm the identity, and the page will not be displayed when the password is entered, just make sure that the input is correct)

sudo gedit /etc/default/grub

In the opened file, change the quiet splash to quiet splash nomodeset and save;

**2. Update the modified grub: **

Open the terminal on the desktop and enter:

sudo update-grub

Just press Enter, the above, the problem is perfectly solved, and then enter the system normally.
