Run Ubuntu 12.04 with a USB flash drive.

At first, I thought it was a very simple installation process. As in the past, I used unetbootin-windows to write the ISO to the USB flash disk. The result showed that there was no such installation process.

If you use ultraliso to write data directly to the USB flash disk, you still cannot do it. I checked the post on the Ubuntu Chinese forum and found that this was the case since u10.10. I cannot do it directly.

 

So we just need to collect it. Next, we will use

Imagewriter.exe

Solved ..

How to use a USB flash drive to install Ubuntu Linux has always been a small number of systems, especially in China, with fewer users than windows, and even a high-end and complex impression, however, over the years, there have been more and more users using Linux. Ubuntu, as a branch with many users in Linux systems, is doing well and is very "friendly ", there are many ways to install ubuntu. This article describes how to install Ubuntu on a USB flash drive.

9. Selecting the first option will format the entire hard disk. If you are not a new hard disk, do not select it! Select the second option

10. This step is difficult, because the partition type and mount point used by Linux are completely different from those used by Windows. The following describes the mount points:

Partition type	Introduction	Remarks
/Boot	Start Partition	Generally, 100 m-200 m is set. The Boot directory contains the kernel of the operating system and the files to be used during system startup.
/	Root Partition	All directories with no mount point specified will be placed under this mount point.
/Home	User directory	Generally, each user is about mb. for special purposes, for example, the file can be enlarged with G. The partition size depends on the number of users. For computers used by multiple users, it is recommended that/home be independent, and normal user permissions can be well controlled, such as disk quota restrictions for users or user groups, and user access permissions.
/Tmp	Temporary Files	Generally, 1-5 GB is set to facilitate the loading of ISO image files. It is also necessary to independently Mount multiple user systems or network servers. The temporary file directory is also one of the most frequently encountered directories.
/Usr	File System	Generally, it takes 3-15 GB, and most of the software installed by usersProgramAll here. It is like the Windows directory and the Program Files directory. In many Linux systems,/usr/local is also used as a mount point.
/Var	Variable data directory	Contains the data to be changed during system operation. The directory size of the data usually changes frequently, and the system log records are also under/var/log. Generally, a multi-user system or network server needs to create this partition, which is very helpful for System Log maintenance. Generally, the disk size is 2 to 3 GB. You can also divide the remaining space of the hard disk into VaR values.
/Srv	System Service Catalog	It is used to store the directory of files required for Service Startup, which is not often changed.
/OPT	Additional Application	Stores optional installation files. Individuals generally include software materials downloaded by themselves, such as office and QQ.
Swap	Swap Partition	Generally 2 times the memory, up to 2 GB
		The following are common partition mount points:
/Bin	Binary executable directory	Stores binary executable programs, which can be called directly through the command line without entering the folder where the program is located.
/Sbin	System Administrator command storage directory	Store Standard System Administrator files
/Dev	Store Device Files	Driver files

Recommended Solution

/boot	200 m
/	20g
/home	50 GB	remaining space
swap	2G

Click/dev/SDA, create a partition table, select the marked idle sub-option, and select Add

11. The file system does not need to be changed. According to the recommendation section in Part 10, select the mount point: //,/boot,/home, and swap. After these settings are set up, click Install now.

Now I am studying Linux, so I decided to install Ubuntu on my computer. Because there is no CD on hand, you can only use a USB flash drive to install it. As a result, I searched for how to install Ubuntu with a USB flash drive on the Internet. Most of the tutorials on the Internet are like finding a dial tool to engrave the operating system on the USB flash drive and then start the computer from the USB. The first tool I used was ultraiso. After the computer was started from the USB flash drive, I found that the cursor kept flashing in the upper left corner of the screen. So I went online to find related solutions. After several hours, I still did not find an effective solution. My heart was so anxious that I began to prepare for giving up. Unfortunately, I saw an article on Baidu Library."How to install opensuse on a USB flash drive"Look at it. I thought it was all about Linux. I can see if I can install Ubuntu through the method he introduced. So I downloaded the tool. Imagewriter.exe Https://github.com/downloads/openSUSE/kiwi/ImageWriter.exe Remember to change the suffix of the image file to. Raw when burning the file so that you can find the image file. After the data is successfully burned, the installation page is displayed. I succeeded! This is just one of my methods. It may be better for you to install the Ubuntu system. I hope you can share it with me.

There are multiple ways to install ubuntu. I have used three methods. 1. Hard Disk installation, 2. Dial installation, 3. USB flash disk installation.

1. Download the CD image

Currently, 12.04lts (long-term supported version) is available)

Http://www.ubuntu.org.cn/desktop/get-ubuntu/download/

2. Preparations before installation

If you want to use a dual system, such as Windows 7 + Ubuntu or Windows XP + Ubuntu, you must prepare for the installation. Otherwise, you will regret the loss of data in the time zone.

Win 7's built-in disk tool (right-click computer-management-disk management) to compress one of the partitions into a space larger than 15 GB without formatting. Remember to compress the space in the disk.

Windows XP does not seem to have its own disk tool. Therefore, the partition magician is used to separate the same space.

3. Installation Process 3.1 hard disk installation

A. in windows, the virtual optical drive uses daemon tools to load the downloaded CD image.

B. Copy the following two folders in the loaded virtual optical drive to the C drive root directory.

. Disk

Casper

C. Double-click the virtual optical drive to go to wubi installation. Select the first demonstration and complete installation.

D. Disconnect the network at this time. The network must be disconnected during the installation process because the network will be automatically updated,

E. Next, select help to start from the CD and click Finish.

F. Restart and the system automatically directs you to Ubuntu for further installation, including partitioning and other operations.

3.2 USB flash drive installation

I used a 1g TF card and a 4G Kingston U disk to test the success. I only need to follow the steps and the 99% will be successful.

After downloading ultraiso, click the "in" icon to open the downloaded CD image.

Choose menu-start-write hard disk image ..., As shown in (note that the selected write method is written as USB-HDD + ):

Click write to wait for the software to write. The software will automatically format the USB flash disk, so the data of the USB flash disk is backed up first.

After completionOpen \ isolinux \ syslin under the USB flash drive directoryUX. cfG,

Comment default vesamenu. c32 into # default vesamenu. c32

4. Formal Installation

After the restart, change the preferred Boot Mode to a USB flash drive. After Entering Ubuntu, click other settings in f6 and select the following three items (use the space key to select)

After selection, a small X is displayed.

ACPI = off

Noapic

Nolapic

Click "Install Ubuntu.

After modification, it can be started normally, but data cannot be read from the CD during operation.

Copy your ubuntu-12.04-alternate-i386.iso to the u disk root directory, and then restart, wait until the error that could not find the CD-ROM appears, press ATL + F2, switch to another console,

Run the following command:

Umount/dev/sdb4
Mount-T vfat/dev/sdb4/mnt/USB
CD/mnt/USB
Mount-T iso9660-o loop ubuntu-12.04-alternate-i386.iso/CDROM

The above/dev/sdb4 is my USB flash drive, and each machine may be different. Check it carefully. After executing the preceding command, you can switch back to ATL + F1, select Yes, and scan again. In this way, you can skip the error!

The last test was not performed because of Multiple tests. Therefore, I do not know whether the test is feasible.
