(a) First to briefly understand some of the concepts of Linux!
1. Differences and links between release and kernel versions: The Linux distribution is a collection of "kernel version + a series of Mount Software", and it is not possible to run as an operating system for a kernel version alone. These mount software has the software package management system, the user management system, the file management system, and so on, the different of the mounting softwares, decides the different release version, such as Ubuntu and Redhat.
2.linux HDD and partition representation: Enter the "fidsk-l" command in the Control Panel
Where/dev/sda1-9 represents the first to nineth partition of the hard disk of the first Sast interface.

How to install 4.linux:
1, CD-ROM installation, most commonly used the most convenient method.
The disadvantage is the need to be on the edge of the machine, such as in the room, not remote control.
There is also a disadvantage is the need to have an optical drive, for the machine without optical drive is more difficult.
2,iso image file installation, no optical drive is required, cannot be re-partitioned and formatted.
3, network Remote installation, it is necessary to realize the configuration of network connectivity, high technical requirements.
4, hard disk cloning, that is, directly from the installed machine on a hard disk clone directly clone a system over,
The disadvantage is that it takes a long time to change the network configuration of the new system after cloning, otherwise the network cannot be used.
(b) below to see how to install the Ubutoun system under the ThinkPad (version e450c) Windows8.1:
I am using a USB stick installation method, is looking for the online tutorial: https://www.jianshu.com/p/16b36b912b02
But the tutorial in the third step "BIOS setup" is not too detailed, no way to do, I found some relevant experience, can refer to: https://jingyan.baidu.com/article/925f8cb8fb062dc0dde0562a.html
Then follow the steps to do it.
If your computer is a Dell Psionic series, then the BIOS setup instructions above will not be appropriate. Because it does not support UEFI format installation, the Windows system cannot be used if it is not installed. So when you order the operation, the computer will ask you if you continue so the original system can not be used, you have to choose not to continue, (then did not take photos, so we can not see, anyway, if you are this model of the computer, and so install the dual system, then you will encounter this problem, you will solve it). But this does not open the Windows system again because the boot entry is missing, what should I do? Refer to: http://www.jb51.net/article/110288.htm#comments
The above is my experience in installing dual systems.
