Teach you how to use the U disk to install Win7 system

At present, many notebooks (especially netbooks) do not have a CD-ROM drive, so the system can only rely on a USB flash drive or a mobile hard disk. With the cheaper price of u disk and its popularity, using U disk to install the system has become the latest reinstalling system solution, so this article today teaches you how to use U disk to install Win7 system, study hard, learn it is your.

The trick of installing Win 7 with a USB flash drive is cool, mainly for two reasons: First, the flash drive reacts faster than the optical drive because it does not depend on moving components. Therefore the installation process will be faster. Second, it provides an easier way to install Windows 7 for systems that don't have a DVD drive. Here's how to use the DiskPart tool to configure the bootable USB flash drive so that you can install the Microsoft Windows 7 operating system using the USB flash drive.

Of course, first we have to prepare a USB flash drive with enough memory space to install Windows 7DVD. The Windows 7 RC DVD is about 2.5G, and it is expected that the RTM DVD will occupy at least this space. A 4G capacity flash drive was selected in our test system.

Remember, the process we are using is to completely reformat the flash drive. So we have to determine if the original data in the flash drive has been backed up.

We hope that the system that installs Windows 7 via the flash drive must be configured to boot from the USB drive. Most new systems are booted from a USB drive. This can usually be done in the BIOS or by pressing the OK button during a separate boot process. In this regard, we have to check the specified hardware for confirmation.

Using the DiskPart Tool

Perhaps you already know that the DiskPart tool is the command line form of the Disk Embedded Management Unit. Its role is to let us manage the disk, partition or script, the number of command prompts. . We can use the DiskPart command in Vista or Windows 7 to configure the flash drive as a bootable device. (Remember that the DiskPart command in XP cannot create a bootable flash drive.)

First, connect the flash drive to your computer. Here we are using the Vista system.

Then, locate the shortcut to the command prompt in the Start menu, right-click its icon, and select Run as Administrator Command. Then respond appropriately to UAC. You can now import the DiskPart tool by entering DiskPart on the command line. Then we will see the DISKPART prompt.

That is, we are already in the DiskPart environment. Below we need to use the List Disk command to locate the USB flash drive. The List Disk command has recognized the USB flash drive and named it Disk 5. We can determine if the USB flash drive is Disk 5 by checking the disk space.

Once the system recognizes the drive number of the flash drive, we will set the focus for the DiskPart environment on the disk. In the example in this article, the USB flash drive is Disk 5, so we will use the command to select Disk 5. Now that the USB flash drive has been in focus, the next thing to do is to delete all partition or disk formatting information. We can do this using the Clean command. The Clean operation should be completed in a flash. After the completion, we can see the information:

Next, create a base partition on the disk using the Create Partition Primary command. After the partition is created, we will see the successful creation message sent by the system, and the focus will be automatically transferred to the newly created partition. Then use the Active command to mark the partition as active. Marking a partition as active helps the BIOS recognize that the partition is a valid bootable system partition.

Once the partition is created and the partition is marked as active, you can prepare to quickly format the disk and install the FAT32 file system with the Format fs=FAT32 shortcut. Once the driver is formatted, you can use the Assign command to assign a drive name to the driver.

The USB flash drive is ready. Now we can exit the DiskPart environment using the Exit command and then close the command prompt window.

Copying Windows 7 files

Copying Windows 7 files is an easy task. Just open Windows Explorer, open the Windows 7 DVD, select all files and folders, and drag all files and folders to the USB flash drive. Remember that the copying operation will take some time.

Installing Windows 7 from a USB flash drive

After loading the Windows 7 DVD into a bootable USB flash drive, you can install the operating system right away. Just boot the system from the USB drive, the installation process is similar to the previous installation, but from the flash drive installation, the process is indeed faster than other installations.
