Install the dual operating system. 0. Introduction:

Ubuntu is a Linux operating system based on desktop applications. Its name is "ubuntu" in the southern African region, it means "Human Nature" and "my existence is because of the existence of everyone". It is a traditional African value, similar to the "benevolence" Thought of Chinese society. Ubuntu is based on the Debian release and GNOME desktop environment. Unlike Debian, Ubuntu releases a new version every six months. The goal of Ubuntu is to provide a general user with the latest and stable operating system built mainly from free software. Ubuntu has a huge community power, allowing users to easily get help from the community. It is easy for everyone to learn and discuss.

Ubuntu's linux-based free open-source desktop PC operating system is very compatible with Intel's Ultrabook positioning and supports x86, 64-bit, and ppc architectures. It fully supports Web browser WPS, sogou QQ Software is one of the most popular Linux desktop systems.

1. lab environment:

Windows 7 amd64, CPU i5

Hard Disk 500 (Note: 60 GB distributed to Linux System)

2. Test preparation:

A. Ubuntu13.04 x86.iso

B. USB flash drive startup tool: (use softdisc or LinuxLive)

C. One USB flash drive with a capacity greater than or equal to 1 GB

D. BCD modification tool (use EasyBCD)

3. Start installation: 1. Create a USB flash drive startup tool:

A download ubuntu image http://www.ubuntu.org.cn/download/desktop
B. Download linuxLive IN THE http://www.linuxliveusb.com/en/download;

Install and create a USB flash drive

2. Install LinuxOS 2.1 and divide 60 GB space in windowOS

Right-click my computer and choose manage> disk management> 60 gb f Disk

2. Shut down and restart. Press F2 when the computer is started to enter the system menu. USB boot is preferred.

23. Insert the USB flash drive and wait for the Ubuntu installation page to go to 2.4 As prompted. Try not to connect to the Internet.

Note: When you are prompted to mount/partition,/boot partitions must be divided.

Switch to the swap partition for 4 GB, and specify 1 GB for/boot. Mount the rest to/(root partition)

After partitioning, select the boot device: the partition where/boot is located.

2.5 modify BCD:

Here we need to use the tool-EasyBCD to modify the BIOS in the computer

After the installation is successful, restart the computer, enter windowOS, and then

Click to add a new entry

Select the partition of Linux

After adding an entry, You can restart it.

2.6 try ....

Restart

Successfully entered:

3. Conclusion: failures and lessons:

This method of installing linux is troublesome. It is in the dual-Operating System of winOS. The main reason why I have not successfully installed it several times is that

1. Change the write mode to permanent write when using LinuxLive, because if the computer fails to read the data temporarily, not only does the linux system fail to be installed, but you also need to re-create and start the USB flash drive.

2. When dividing Linux Mount files, swap partitions must be managed, and/boot must be mounted, otherwise, the operating system is no longer a Windows dual operating system but a linux dual operating system. The two are different.

The CPU temperature increases after the three-part laptop is installed. This is because no suitable graphics card driver is installed. You can find the corresponding driver in UbuntuOne, but there is a simpler method:

Echo OFF>/sys/kernel/debug/vgaswitcheroo/switch

This sentence can be written in

In/etc/rc. d/rc. local, use the touch command to create a file with the same name.

File Content:

#! /Bin/bash
Echo OFF>/sys/kernel/debug/vgaswitcheroo/switch

Modify the File Execution permission

Chmod + x rc. local

TIPS:

By installing the dual operating system this time, I have learned a lot of technical knowledge, read a lot of documents from the Forum, and also used the theoretical knowledge of the operating system course during college.
