< >win7 system using USB stick to install ubuntu_12.04 to realize the dual system tutorial

at present, the online circulation of the installation of Linux system Tutorial is colorful, before you want to use hard disk installation, because the configuration problem is not properly installed, is now studying the next U disk installation, according to some information on the Internet and their own summary, in Windows7 The system uses a USB stick installation to install Ubuntu 12.04 and boot into the Windows7 and Ubuntu 12.04 dual systems.
Ubuntu 12.04 Online experience: http://www.ubuntu.com/tour/zh-CN/
the detailed steps are as follows:
1, this time using 64-bit ubuntu-12.04.2 desktop version, download 64-bit Ubuntu system ISO image file ubuntu-12.04.2-desktop-amd64.iso,:http://www.ubuntu.com /download/desktop or directly using Http://mirrors.neusoft.edu.cn/ubuntu-releases//precise/ubuntu-12.04.2-desktop-amd64.iso
2, download the production of Linux U disk Boot tool (green version) Universal-usb-installer-1.9.3.0.exe, the specific use of the method described: http://www.pendrivelinux.com/ universal-usb-installer-easy-as-1-2-3/
3, using Universal-usb-installer-1.9.3.0.exe tools to make Ubuntu-12.04.2-desktop-amd64.iso into a U disk boot system
4, the computer division out an empty disk, the size of 20G is sufficient, can also be based on personal preferences, sub-100G or so also line. The empty disk is not named, that is, do not assign the letter, do not format. (Here, we no longer repeat the sub-disk method, the method is very simple, now the disk Management in the notebook can be divided, is the new compressed volume as simple)

The empty disk also does not need to create a new compressed volume.

5, the computer shutdown, restart, to be on the screen when the continuous press F12 or F8 key to enter the boot interface (different computer may be key, the author's notebook is F12, desktop for the F8), after entering the boot interface, through the computer keyboard on the left and Right arrow keys adjustment options, we choose via USB Start the entry and press ENTER

6, into the immediate appearance in front of the friend extension system of the graphic installation interface, very easy to operate. Look at the picture

7, choose to continue to enter the following interface

8, note: Red circle can not be ticked, do not tick the installation speed will be faster, then choose to continue, the following interface appears, and choose the other options that one option!

9. Other options (Manual partitioning:/,swap,/home,/boot), select "Other Options" and press the "Continue" button. As shown in. Here we set up four partitions, each of which is/,swap,/home,/boot.

After this step must find the red underlined part of the free interval, the original you divided out the size of the plate, the figure will show how big, and then double-click on the empty section will pop up the allocation box to let you assign. The option for the Yellow Circle section must select the area that is divided into/boot (should be an option for the entire hard disk size).

A total of four partitions, the author partition as follows, more reasonable:

1) , the type of the new partition: Select Primary partition,
New partition capacity: Enter the size of the allocation, in megabytes
the location of the new partition: By default, start
for: Select the file system used by the new partition, and use the default EXT4 log file system
mount point: Select/ ”。 Size 10G (can vary by individual)
2), create swap space
and select free space, click the Add button.
type of new partition: Select logical partition
New partition capacity: Enter the size of the swap space allocation, in megabytes (MB)
The location of the new partition: By default, start
for: Select swap space
Swap space instead of selecting a mount point, So the mount point is gray is not selectable
The author proposes to swap partition 512M
3), create the "/home" Partition
continue to select free space, click the "Add" button.
type of new partition: Logical partition
New partition capacity: Remaining space
Location of new partition: Start
for: Select the EXT4 log file system
mount point:/home. The
Click OK button.
The author of this partition 12G (this main personal document)
4), create the "/boot" Partition
continue to select free space, click the "Add" button.
type of new partition: Logical partition
New partition capacity: 200M new partition location: Start
for: Select the EXT4 log file system
mount point:/boot. The
Click OK button.
Because we install the friend extension is installed under the Windows7, want is a dual system, so to create the/boot partition,
Otherwise this can be omitted.

Note:/partition is the Linux system file system partition, similar to Windows system disk, such as C drive, swap for swap partition, generally memory twice times,/boot partition 200M enough;/home for personal document partitioning

Important NOTE: When installing Ubuntu partition with U-disk, all disks must be set to logical partition, including root directory/partition, otherwise it will not be possible to continue partitioning, this is the lesson that I experienced personally, remember. The real reason: in the Windows system to install the Ubuntu system, the primary partition has been occupied by the Windows system (up to four primary partitions), such as more than one primary partition in the window system, when the Ubuntu system is created, cannot be set to four (/,swap,/ Home,/boot) Primary partition, so it is not possible to continue partitioning when it is set to primary partition, it is recommended to set to logical partition.

10, select Continue, go to the next step, and set the region as: Shanghai, select the language in the next steps

11, Gnu/linux and UNIX are multi-user (multi-user) operating system, a gnu/linux can allow multiple users to use simultaneously. To facilitate the management of each user's files and resources, each user has their own user account and password (password). Ubuntu will first ask you to create a user account that belongs to you, so you will see the following screen asking you to enter the data and password for the first user of the new Ubuntu. It is also easy to stop repeating it.

12, choose to continue, go to the next step, and follow the setup to complete the installation, see the following screen indicates that you have successfully installed Ubuntu, you can press "Restart Now" (Restart) reboot into Windows7

13, the installation of good friends to help extension to boot settings. Here we use EasyBCD2.2 this software to set the boot entry, this software can search their own download, you can also download the following share (safe green)
http://pan.baidu.com/share/link?shareid=6866&uk=621590515 download good after installation, run. Follow the steps to see the diagram:

Four steps have been marked, where the third step of the name can be entered in Ubuntu 12.04, the fourth step is to choose your installation system time of the/boot disk, 200M of that, generally will show 199M, choose to

14, all completed, restart the computer,

Select the third to enter the new installation of the friend extension system, enter the following will appear a process, do not have to ignore, enter the first (the default is also select the first)

15, a few seconds after the system appears in the Ubuntu System Login window, enter the password previously set to enter the system, the entire 64-bit ubuntu-12.04.2 system desktop version of the installation completed.
