Beautiful Tragedy

Recently I start to open my first new project about the path planning of unmanned vehicle. Ubuntu 18.04 is an effective system to simulate and develop the program. But windows system is necessary for me to complete the homework. Considering the double need i decide to set up a double system. Although i have completed the first step of open my project coperated with the prodecessor, there are still experiencing which is worthy for me to share with all of you so that you can avoid a lot of pitfall when you prepare to do the same work with me. Please let me describe this experience shortly. I made an throughly analysis about this whole situation, and two problems are still haunted around myself. First i do not know what my problem is, Secondly how to solve the problems still belong to one lof my shortages. Obviously it is impossible to refer the effective material on the Internet if i am not able to realize what is my problem. After coperated with the professional for several days, i hope to write this first record so memorize this beautiful tragerdy.After read a lot of blog ,i just makde a uneffective method to set up an ubuntu after i read a lot of blog. Without doubt this first try is failure and the original win10 system were broken by myself becaue i ignored the speciality of the conflict exist in most common things. i just follow the most simple method namely click continue every timw when i met it. Apparently this system is uneffective. Due to the ignorance about the method of download original system. My origianl win10 haung out. But this time i know how to download the broken system just using EasyUEFI or Easybcd. And then format the disk which were used to insert ubuntu 16.04.
Next, Not only do i set up win10 again, but also the ubuntu should be configured and set up based on the win10 system. What differente this experience with the former one is i did not follow the method. It happend that i succeed this time but the ubuntu16.04 is still haunged when i set up the wifi hardware and sofeware.I still remeber the procedure when i solved this problem. First i click software and set up and look for the domestic mirror source.
second i find a mirror source which support my ubuntu 16.04 system.
thrid

sudo cp /etc/apt/sources.list /etc/apt/sources.list.backup

backup original source list.
replace the original source list with copy pattern

sudo gedit/etc/apt/sources.list

and then

sudo apt-get update

with adding an extra drive to end this step.

this is an official guide about how to configure wifi in Ubuntu 16.04.
in the fifth step the graphical interface can not into. As a rookie,it is impossible for me to solve this problem except for setting up again. But i realize what my problem is. I guess i wrongly click the drive option in last step and it is no doubt the drive problem, which means i can not restart my graphical interface of ubuntu.I input the apssword again and again but the interface of password inputing still haunt in front of my face. Oh god you can not imagine how much i want to push this thin interface and into the graphic interface directly After scan the past experience on CDSN , If it is the proble of the NIVADA drive, i need to follow these steps i guess download the original NIVADA is the first step. （1）进入文本模式：CTRL+ALT+F1
（2）Uninstall any previous drivers:

sudo apt-get remove nvidia-*
sudo apt-get autoremove

(3)Uninstall the drivers from the .run file:

sudo nvidia-uninstall

（4）restart and login normally
（5）set up the drive again

(1)Ctrl+Alt+F1
 (2)sudo service lightdm stop
 (3)sudo ./NVIDIA-Linux-x86_64-381.22.run -no-x-check -no-nouveau-check -no-opengl-files

（6）sudo service lightdm restart
Although i realize how difficult the solving procedure of predecessor is, but i know i do not need to refer the precedure in

One the one hand, time will be wasted and the problems are still hang on. Maybe through adopting the procedure mentioned above is helpful but there is still the shortcut no matter how difficult of the problems is.
And then i was advised to set up the newest pattern 18.04. The wifi have been configured automatically which means i do not need to allocate the wifi manually. But it is not influent and smooth at the start of click the continue. Even i can keep clicking the continue button, Chances are high that i still cannot go into the graphic interface. so i realize i need to colse the N drive at the first. And the N drive need to be quite when i prepare to restart the interface.
As long as i can not go into the interface i guess it must be the drive problem. All i have to do is to download the drive.
Specific step is as follow.
First close the secure boot in BIOS.
Second Click e and go into the grub pattern before go into the Ubuntu install interface.Replace quiet splash with the nomodeset.
Third I feel so sorry that i do not clearly figure out how to stop the N drive.
