This article mainly introduces "the detailed steps of installing ubuntu12.04 on hard disk". In daily operation, I believe many people have doubts about the detailed steps of installing ubuntu12.04 on hard disk. The editor consulted all kinds of materials and sorted out simple and easy-to-use methods of operation. I hope it will be helpful to answer the doubts of "detailed steps of installing ubuntu12.04 on hard disk". Next, please follow the editor to study!

Preparation before installation:

1. Create an unassigned hard drive.

First select a hard disk partition of more than 30g as the target hard disk to install ubuntu, back up its original data and format it. Next, the actions under win7 are as follows: click start-> Control Panel-> system and Security-> Administrative tools-> computer Management-> disk Management. Find the hard disk partition you just formatted and right-> delete the volume. This leaves us with an unallocated hard disk space to install ubuntu.

two。 Download the image.

To install ubuntu, you must first have an installation image of any version of it (preferably the latest version). Linux is an open source operating system, and ubuntu is one of its excellent distribution, so getting an installation image of ubuntu is very easy and free. Specifically, you can download it from the ubuntu Chinese site: http://ubuntu.org.cn/getubuntu/download/, but the latest version of the Chinese site is 11.04 lower than 11.10. You can download http://www.ubuntu.com/download from the ubuntu official website, but because the official website is foreign, it will be slow. If you know how to use six-dimensional space, it is recommended that you download http://bt.neu6.edu.cn from six-dimensional space.

3. After we have the installation image, we need to make a boot file. In the downloaded iso file, under the casper folder directory, find vmlinuz and initrd.lz (the file name may also be initrd.gz) to extract, and copy to the root directory of C disk (there is no need to extract the entire casper folder). Download the latest version of the software called EasyBCD and install it. Start EasyBCD and select Add new entry- > NeoGrub- > Install, and then at the new interface point: configure, menu.lst appears, and add the following:

The code is as follows:

Title Install Ubuntu 12.04

Root (hd0,0)

Kernel (hd0,0) / vmlinuz boot=casper iso-scan/filename=/ubuntu-12.04-desktop-i386.iso ro quiet splash locale=zh_CN.UTF-8

Initrd (hd0,0) / initrd.lz

Note: the red font part is the file name of the ISO image file that needs to be installed. Adjust according to the actual situation, initrd.lz may also be initrd.gz, please make sure the file name is correct, pay attention to the same case. (some students' win7 installation time partition, there is a 100MB system partition in the first position, so the so-called C disk is not (hd0,0), it should be (hd0,1); again, in case of back, you should test under grub4dos to see which partition it should be. )

4. Restart the computer. The following two options should appear on the boot screen:

The code is as follows:

Windows7

NeoGrub Bootloader

Select NeoGrub Bootloader to enter live cd (tested that this hard disk installation method is more suitable for the desktop version of ubuntu, if it is the alternate version may not be able to enter the live cd screen). At this point, we can see the ubuntu installation preparation screen. Here you need to type a command through the terminal, which may not know what to do for friends who are exposed to the linux operating system for the first time. Let me explain it in detail.

In the upper left corner of the live cd installation screen, find the black button with ubuntu logo, which is somewhat similar to the start button under windows. Click and type the letter t in the search bar that appears, find the terminal terminal, and click. A window runs and type a command:

The code is as follows:

Sudo umount-l / isodevice

Then enter and close the terminal. Click the install ubuntu icon on the desktop. Start the installation!

5installation process.

After reaching the appropriate steps, select the installation type according to the figure below

Select the last item to customize the partition

Find the unallocated zone prepared in the first step, and then start partitioning under ubuntu:

/ more than 15g is recommended / 30g or more is recommended for home, partitioned separately. Swap recommends less than 2G. / boot can not be partitioned separately. If it is partitioned separately, more than 300m is recommended.

6. Finally, wait for the installation to be completed.
