Recently are learning Common Operation Command Linux system, so whim, I want to own install a Linux system practice it on the Internet for a long time information, and finally on their computers successfully installed to achieve a Windows + Linux dual system, will own the installation process recorded. Here is the installation of the operating system Ubuntu-1604.3, Download:
https://www.ubuntu.com/download/desktop
After the download is complete is a .iso image file, you need to burn to a disc or made U disk boot, 2G U disk has a small big enough to use, occupy about 1.5G of space after made. Baidu search download UltraISO installation, click File → Open to open, select the downloaded image file to open
Then select Start menu bar → write disk image, select the hard drive U disk device, write mode select USB-HDD +, there must not wrong, click the writing start to write image data file to the U disk
When burning is complete as shown:
U computer disk storage device name becomes the Ubuntu 16.0
To achieve Windows7 + Linux dual system, we must first partition the disk, it means the computer disk space vacated part of a Linux system, such as computer hard drives to 500G, Windows systems use 450G, 50G also used to install Linux system
Step disk partition as follows:
Right My Computer, select Manage, select Disk Management in the window shown here is that all the system partitions, select a spare capacity of the larger disk, right click and select on the disk "compressed volume"
Selection of size distribution of Linux systems, can be assigned their own set according to how much, if not a lot of processing programs and data, then the general 20-30G enough, the distribution capacity of 50G here for Linux
Click on the size of the installation space compression, compression after completion will be more of an unassigned space in the partition, which is compressed from the disk, for use when a Linux system installed
After a good distribution of space for a Linux system, restart your computer, press F12, select Use U disk to start when the computer starts
After selecting U disk boot Ubuntu system will enter the installation interface, select Chinese on the left, click to install Ubuntu
Next, choose whether you want to connect wifi, you can choose to connect or may not connect, after connection can choose to install third-party software and update, if you do not connect, you can enter the system to install the update after the system installation is complete
Click Continue, enter the installation type selection, to select other options here, so that we can be their own partition
Next, enter the partition settings
Select free partition is assigned a Linux system 50G space, click on the "+" partition as Ubuntu. In the Linux system, each with up to 16 hard disk partitions, where only a few of the most popular new directory
swap: swap space, typically the size of physical memory size or twice the physical memory
/ Boot: Linux kernel and file system boot procedures need, usually set to 200M
/ Tmp: temporary file system will not be saved when the system is restarted
/: Root directory, 10G-20G
/ Home: User working directory to save the file, will be assigned the remaining space
After the partition is complete, click on the install now, you will be prompted partition has been overwritten, click Continue, setting the place where, to continue to the next step
Keyboard layout interface, continue
Username and password settings, set name, computer name, user name and password, click Continue to enter the system installation
You will be prompted to reboot after the installation is complete wait
After the restart can choose to enter or Windows7 operating system Ubuntu
After entering the Ubuntu system will enter the login screen, the user name and password you just set up a user name and password, enter the password to access Ubuntu system
最近正在学习Linux系统的常用操作命令，于是心血来潮，想自己安装一个Linux系统实践一下，在网上找了半天资料，终于在自己的电脑上成功安装了，实现了Windows+Linux双系统，将自己的安装过程记录了下来。这里安装的是Ubuntu-1604.3操作系统，下载地址:
https://www.ubuntu.com/download/desktop
下载完成后是一个.iso的镜像文件，需要刻录到光盘上或者制成U盘启动，U盘有2G小大就足够用了，制成后大约占据1.5G的空间。百度搜索UltraISO下载安装，打开后点击文件→打开，选择下载的镜像文件打开
然后选择菜单栏的启动→写入硬盘映像，硬盘驱动器选择U盘设备，写入方式选择USB-HDD+，这里一定不要选错了，点击写入后开始将镜像数据文件写入到U盘中
刻录完成后如图所示：
计算机中的U盘存储设备名称变为了Ubuntu 16.0
要实现Windows7+Linux双系统，首先要对磁盘进行分区，说白了就是将电脑的磁盘空间腾出来一部分给Linux系统使用，比如电脑硬盘为500G，Windows系统使用450G，还有50G用来安装Linux系统
磁盘分区的步骤如下：
右键我的电脑，选择管理，在窗口中选择磁盘管理，这里显示的是系统的所有分区，选择一个空闲容量较大的磁盘，在磁盘上点击右键，选择“压缩卷”
选择为Linux系统分配的空间大小，分配多大可以自行根据需求设置，如果不需要处理很多程序和数据的话一般20-30G就够用了，这里为Linux分配了50G的容量
设置空间大小后点击压缩，压缩完成后会在分区中多出一个未分配的空间，这就是从磁盘中压缩出来，供Linux系统安装时使用的
为Linux系统分配好空间后，重启电脑，电脑启动时按F12，选择使用U盘启动
选择U盘启动后会进入Ubuntu系统安装界面，在左侧选择中文，点击安装Ubuntu
接下来会选择是否要连接wifi，可以选择连接，也可以不连接，连接后可以选择安装第三方软件及更新，如果不连接，可以在系统安装完成后进入系统安装更新
点击继续，进入安装类型选择，这里要选择其他选项，这样我们可以自己进行分区
接下来进入分区设置
选择空闲分区，就是为Linux系统分配的50G空间，点击“+”，为Ubuntu进行分区。在Linux系统中每一个硬盘最多有16个分区，这里只新建几个最常用的目录
swap：交换空间，大小一般为物理内存的大小或者物理内存的两倍
/boot： Linux的内核及引导系统程序所需要的文件，一般设置为200M
/tmp：系统的临时文件，系统重启时不会保存
/：根目录，10G-20G
/home：用户工作目录，用来保存文件，将剩余空间都分配
分区完成后，点击现在安装，会提示分区已被改写，点击继续，设置所在地方，继续下一步
键盘布局界面，继续
用户名和密码设置，设置姓名、计算机名、用户名和密码，点击继续后进入系统安装
等待安装完成后会提示重启
重启后就可以选择进入Windows7还是Ubuntu操作系统
进入Ubuntu系统后会进入登录界面，用户名和密码就是刚才设置的用户名和密码，输入密码就可以进入Ubuntu系统
