Install Windows 7 Using USB Drive

These days every second person want to use Netbook because of its portability. But Netbook have one big problem & the problem is NO OPTICAL DRIVE installed in it. So in this way every one thinks that how we install the operating system in the Netbook.So dont worry guys, you can install the operating system using your USB Flash Drives & i will tell you that how to make a USB drive which is bootable also! A USB storage device needs to be 4 GB or larger if you want to use it as a Windows 7 installation source. This is because the x64 installation files are approximately 3.2 GB in size and the x86 installation files are approximately 2.5 GB in size. You use one architecture's installation files only when preparing a deployment from a USB storage device. The USB storage device should use the FAT32 file system.

To prepare a USB storage device as an installation source for Windows 7, perform the following steps:

1. Connect the USB storage device to a computer running Windows 7 or Windows Vista. Ensure that the storage device has no data stored on it that you want to keep (or that you have moved such data to another storage device) because this procedure removes all existing data.

2. Open an elevated command prompt and type diskpart.


3. At the DISKPART> prompt, type list disk. Identify which disk connected to the computer represents the USB storage device.


4. At the DISKPART> prompt, type select disk X where X is the number of the disk that you have identified as the USB storage device.


5. At the DISKPART> prompt, type clean. When the disk is clean, type create partition primary.


6. At the DISKPART> prompt, type format fs=fat32 quick. When the format is completed type active and then exit.


7. After you have completed these steps, copy all the files located on the Windows 7 installation DVD to the USB storage device.


8. Configure the BIOS computer on which you want to install Windows 7 to boot from the USB storage device. Attach the USB storage device and then reboot the computer to start installation.


There are several disadvantages to using USB storage devices as a Windows 7 installation source. Although they are reusable, USB storage devices are more expensive than DVD-ROMs. USB storage devices are also not suitable when you have to deploy Windows 7 to a large number of computers over a short amount of time because you need to attach a USB device to each computer to install Windows 7 on it. For example, if you wanted to deploy Windows 7 to 100 computers, you could configure 100 USB devices with the Windows 7 installation media and answer files for unattended installation, or you could configure one Windows Deployment Services (WDS) server and perform the installation over the network—a much more convenient option.
