Install win8 system to U disk /hard disk Take win8 with you

Install the system to a USB flash drive (or a mobile hard drive), carry it with you, and go where you plug in the USB flash drive. Don't worry about synchronizing files, don't worry about personal habits, don't worry about security issues, everything is as simple as that! Mobile office, this is the king of the road, what & ldquo; cloud & rdquo; are weak!

This is an example of Microsoft's latest operating system
Win8! There are many ways to circulate on the Internet. Here is an example of the simplest way to look at it. (meaning means that the U disk is installed as a C disk system, and it can be booted directly to Win8 without any installation operation on any machine.)

We only need to prepare the following tools: (Article Tail provides download) 1, Win8 system image 2, Windows
To Go auxiliary software multi-thread optimization special edition

First we must first extract the install.wim of the sources folder in the win8 image, everyone WinRAR can be used to extract simple and convenient. Then plug in our U disk (or mobile hard disk), use the system's own disk management to set the U disk to "active area", this step is very important, if not set, it may cause the U disk boot can not boot the system! Right click on the drive letter and set to “activity”

Open Windows To Go auxiliary software (win7 users please run with "administrator privileges"), select the install.wim file that has just been extracted, “check the installed disk” this, Select your own U disk or mobile hard disk, here you need to pay attention to is that the storage device must be larger than 20G space! Otherwise there will be tips! Storage devices are still recommended for USB3.0 specifications~


Less than 20G will be prompted!

After you have chosen, click to start the installation! Fully automatic, no manual intervention required. After the start, the software will automatically format the memory, so what information is still backed up in advance. Then pop up a CMD command line ~ there will be a progress bar and time estimate, everyone wait! It is strongly recommended to use the multi-threaded optimized version recommended in this article, which will reduce the installation time of this step. The installation time of the 3.0 device install.wim is about 20 minutes! Please be patient, don't close the command line window!

After everything is installed, the CMD command line will disappear automatically. We will close the software, restart the computer
, and enter the Bios settings startup item~ each The motherboards of the computer
are different. You can check the instructions on your motherboard for modification. Let's take my Lenovo desktop as an example. After rebooting, click the DEL button to enter the Bios settings.

According to the picture, select the second item on the left.

Next select Boot Device

1st Boot Device Item Selection, Removable Dev

You can enter Removable Dev to confirm whether the motherboard can recognize come out!

Okay~ After the setup is complete, save and exit, you can see Win8 after reboot! The first start will be a little slower, wait patiently~ The operation after that is still very smooth, and it is no different from local operation!

Analysis of the principle:

First use the diskpart command to empty the disk, create a partition, format it to NTFS format and set it to Activity area!

There is a call to Imagex.exe in the Windows Automated Installation Kit (AIK) (used to install install.wim to the specified partition) and bcdboot in the Windows 8 operating system. .exe (used to set the boot of the specified partition)

The command is as follows:

imagex.exe /apply install.wim 1 Drive letter: This step means to install install.wim to a disk. Change the letter to the letter of your mobile device.

bcdboot.exe Drive letter: windows /s drive letter: /f ALL This step is for write boot and has started Windows on this device. The meaning of the drive letter is the same as above.

The whole process and the explanation of the principle are over! Very simple! The tools provided below can shorten the installation time. The following principles can be seen and understood. The tool is convenient for us to use everyday. Entering this bunch of code is estimated to make many friends discouraged! If you have succeeded through my method, then let's reply here!
