Ubuntu is installed on a USB flash drive in windows.

Just in the New Year, duang, let's learn how to install Ubuntu dual systems with a USB flash drive in win7:

I. Prepare materials

Background Environment: win7 System

Prepare file :( download link: http://pan.baidu.com/s/1o6vAXfG)

1) Ubuntu: ubuntu-14.04.2-desktop-amd64.iso

2) USB flash drive system installation software: Uiso_9cn

3) boot guide tool: EasyBcD_1 @ 58174

4) mbr boot repair tool: Bootcie

Ii. Practice

1. for Ubuntu system partition:

Click -- computer -- Right-click -- manage -- disk management. The partition status of your computer's disk is displayed.

Select an empty disk or a surplus disk to compress the volume and obtainGreenAvailable logical volume (at this time there is no drive letter, will be used when installing Ubuntu, as the system disk, the size of their own settings, generally greater than 20G)

2. Create an installation disk for a USB flash drive:

(1) Open Ultraiso, select the image file, that is, the ubuntu-14.04.2-desktop-amd64.iso

(2) Select "start"-"Write hard disk image ":

Hard drive: select your USB flash drive

Write method: USB-HDD +

Select "write" (wait until the last four or five minutes)-"return"

See: http://jingyan.baidu.com/article/a378c960630e61b329283045.html

3. Install Ubuntu:

(1) boot and restart, go to the boot settings page, and select USB (that is, your USB flash drive) to start. Different boot keys are generally F12, F2, and F9;

(2) On the Ubuntu installation page, select Install Ubuntu)

(3) The online installation or non-Online installation interface is displayed: (some system versions do not have this interface. We recommend that you do not use such a system. It will be troublesome to use it later)

If the network speed is poor, we recommend that you use the "non-Online installation" method. If the network speed is good, you can use the "online installation" method (download updates during installation)

Install this third-party software: this software is used to play audio and so on. You can choose to install it or not (I chose to install it)

Click "continue)

(4) When the partition page appears, you must select the "Other Options" at the bottom and click "continue)

(5) On the system drive letter page, select free space. The following option (the device that installs the boot pilot) remains unchanged, that is, your entire computer disk (compare the size and confirm it is your computer disk)

(6) Select "+" to create a new partition:

Create four partitions: Root partition (/), swap partition, boot partition, and home partition.

Partition introduction:

Root partition: other partitions are attached to this partition. Generally, 10 Gb is recommended.

Swap partition: generally 1-2 times the computer memory size (512 MB ...)

Boot partition: The boot partition of the Ubuntu system. Generally, Mb is enough (required for later boot settings)

Home partition: the user stores the file area (as big as possible)

Partition options:

Root partition: Size-10 GB recommended, new partition type-Primary partition, new partition location-space start position, used-select "/"

Interactive partition: Size-recommended 2 times memory, new partition type-logical partition, new partition location-space start position, used for-select "swap space" (/swaparea)

Boot partition: Size-200 MB recommended, new partition type-logical partition, new partition location-space start position, for-select "/boot"

Home partition: Size-remaining free space, new partition type-logical partition, new partition location-space start position, used for-"/home"

Note: The new partition type here is generally the best option. If you select the primary partition as the primary partition, you may not be able to partition, because the disks in windows may be primary partitions, which may cause problems.

(7) select the location (your location, I am in Beijing, so fill in Beijing)

(8) keyboard layout (select "Chinese"-"Chinese ")

(9) set the user name and password (required)

6. solutions to common networking problems:
