Install Ubuntu 14.04 on the Win7 system using the disc boot disk (dual system, independent)

1 Introduction

VirtualBox install different types of operating systems on the host system Win7, using the guest system in this way Ubuntu has been around for a long time, starting from the initial Ubuntun10.04 to the present 16.04. In addition, the lab of another desktop installation is Ubuntu14.04, I just ran the program, and the laboratory printer server installed is Ubuntu10.04. It can be said that in this environment is not familiar with the Ubuntu system to use the past.

My notebook followed me for almost 5 years, and 1 months ago, I developed a humanitarian spirit. I lent my desktop to another chick in the lab, and these days I just needed to run a matrix decomposition program. For almost 2 days, the installation of the Theano package was not set up on the Win7 system. No, I only set it on the guest system Ubuntu 14.04, but I can't stand the speed on the virtual machine. Say it slow, not slow, but there is a clear difference with the host system, which I can not stand.

When I cleaned the disc in my drawer, I accidentally found a Ubuntu12.04 installation disk, which told me that I could be installed on the computer with the Win7 system. Now there's only one way to run my matrix decomposition program.

Search from the search engine a lot of solutions, after their kneading and combined with their own success in practice, to form this article. Many of the programs on the network are either unclear or not in the image, and are hard to read. In order to overcome the shortcomings of other programs, this paper aims to express clearly, and the key points and focus on special hints for readers and system installation enthusiasts a good reference and learning materials. These key points and the operation of the focus of the slightest careless of the overall loss of the fate.

2 tools and materials required

1. A computer that installs the Win7 system, we need to install the standalone dual system ubuntu on it;
2. An Ubuntu system installation disk; If you don't have one on hand, you can burn it yourself, see the blog post for the Burn method.
3. installation files for software EASYBCD. The purpose of this software is to set the start-up choice of different systems, the sorting of the system, and their respective waiting time. I'm using version V2.2, and you can try other versions as well.

3 method steps

1. first divides the hard disk space for the Ubuntu system that will be installed on its own Win7 system. We take advantage of the tools that the Win7 system comes with. Right-click Computer=>manage=>storage=>disk Management (Local) and right-click on the last hard drive partition F-disk (of course, on your own computer, choose a larger amount of space depending on the actual situation.) ), and then select Shrink Volume, such as:
   
   Enter the space you want to compress on the dialog box that appears, and click Shrink, such as
   
   , to continue to the next step, do not give the space a letter. When you are finished,
   
2. installs the Ubuntu system . Restart your computer and put the disc in the CD-ROM drive, set the computer to boot from the CD-ROM and enter the Ubuntu system installation screen. You directly click on the install Ubuntu can, and I because of the delayed try Ubuntu (participate), into the use of Ubuntu inside. Not afraid, in the trial system we can also install.
   
   After entering the trial system, you will find an install Ubuntu icon on the desktop, click on the icon to enter the system installation process. Wait a minute, the following interface appears:
   
   on the upper bound surface Select something else to enter the next partition interface. Here, we are going to set up 4 partitions for the Ubuntu that will be installed, the following table is my partition condition:

Partition name	space Size (MB)	Use
/boot	200	Used to start Ubuntu
/	30000	For installing system programs and software
Swap	2000	Equivalent to the memory extension, do not exceed the computer's physical memory
/home	All remaining space	Information for storing the user

First we look at the partition of/boot, such as:

Be careful to partition in the free space, otherwise it will cause serious consequences. Click on the 2 plus sign to add a partition, change the size on the pop-up partition interface, and select/boot on Mount point. In a similar way, allocate the appropriate space for/and/home. Here is a special explanation of the swap partitioning method, such as:

Select Swap area in use as, and the other method of spatial configuration is the same as/home. The following is a summary of the partition, for example, to remember the device name corresponding to/boot, this is sda8:

The next installation process is relatively simple, select the country, keyboard layout, enter their own user name, computer name and password, always click Next. The following interface will appear when the installation is successful:

Click here to restart now.

Note: After the installation is complete, the crash occurs when you restart your computer. At this time do not fear, so at this point the control is still in the Win7 system hand, we only forced to shut down the machine.

When we start the computer again, we will find that we have entered the Win7 system, and there is actually no Ubuntu boot option on the computer screen. At this time our software EASYBCD (installed in advance on the Win7 system. ) comes in handy.
3. Set the Ubuntu startup item on the WIN7 system. The use of EASYBCD software is simple, installation can be set up:

In the Name text box we fill in an easy-to-remember meaningful name that appears on the boot entry. In the Drive drop-down box, select Partition5, because only the/boot partition, we allocate a space of 190MiB.
4. Once again booting the system, we will find that the options for Ubuntu appear in the boot options. Check it into Ubuntu system and we've installed it successfully

4 Summary

Installing a standalone dual system on a computer is a very practical thing, and it is worth every one of us, especially computer enthusiasts, to exercise. This example is explained in the installation from CD-ROM, in fact, we can completely install Ubuntu from the USB stick, just replace the installation of the Ubuntu step with a USB stick to install. Hopefully this article will help you with installing a dual system.
