Install Windows 7 on Netbook from USB

Preparing a Netbook for a New Operating System

Installing a new operating system on a netbook lacking a CD/DVD drive is generally straightforward, particularly with tools like Unetbootin. However, installing Windows 7 necessitates a few preliminary steps to successfully load the latest Windows OS onto your device.

This guide details the process of creating a bootable USB flash drive using either Windows XP or Windows Vista. We will cover transferring the necessary files to the USB drive and subsequently installing Windows 7 onto your netbook directly from that USB source.

You will require a USB flash drive with a minimum capacity of 4GB, a Windows 7 installation copy, a program capable of extracting the contents of your Windows 7 image file – such as 7-Zip – and a computer running either Windows XP or Vista.

Ensuring USB Boot Capability

Prior to commencing, verify that your netbook can boot from a USB device. This is typically achieved by accessing the BIOS settings during startup. Most netbooks allow access by pressing F2 as the system initializes.

Within the BIOS settings, navigate to the Boot tab and confirm that 'USB HDD' is included in the Boot priority order. If present, your netbook should be capable of booting from the USB flash drive.

Formatting the USB Flash Drive

The initial step involves formatting the USB drive to prepare it for use. Locate the USB drive within your Explorer window, right-click, and select 'Format'. The recommended file system for this process is NTFS.

Windows XP users who do not see the NTFS option in the dropdown menu should consult a guide to enable NTFS formatting for their USB flash drive.

Activating the USB Partition

Windows XP users will now utilize the MBRWizard program. Download the zip file and extract its contents to the C drive. Then, open the Windows Command Prompt. (Click the Start button, type 'cmd' in the search field, and press enter.)

Employing MBRWizard and the command prompt, you will activate the partition using the following commands:

cd\

cd mbrwiz2.0

mbrwiz list

Your USB drive should appear in the list of disks, such as Disk 1, as shown in the screenshot.

Next, enter the following command:

mbrwiz /disk=X /active=1 (Replace X with the number corresponding to your disk)

Confirm the action by answering Yes when prompted: "Are you sure you want to set the partition(s) Active?"

Windows Vista users can bypass the MBRWizard download and proceed directly to the command prompt, entering the following commands:

Diskpart

list disk

Identify your USB flash drive (e.g., Disk 1) and then type:

Select Disk X (Replace X with your disk number)

List partition

Select partition 1

Active

A message confirming activation should appear: Diskpart marked the current partition as active.

Extracting Windows 7 Files

Locate your Windows 7 image file and extract its contents into a folder named Windows7 within the C drive. These extracted files can be deleted after the installation process is complete.

Return to the command prompt window and execute the following:

cd Windows7\boot

bootsect /nt60 X: (Replace X with the letter of your USB drive – for example, G:)

The following message should be displayed:

The final preparatory step involves transferring the Windows 7 files to the USB drive, utilizing Unetbootin.

After installing Unetbootin, select Diskimage and browse to your Windows 7 image file. Choose the prepared USB drive and click OK.

Unetbootin will require approximately 15 to 30 minutes to copy the files onto your USB drive.

Installing Windows 7 from USB

The final stage is installing the new operating system. Connect the USB drive to your netbook and initiate startup. Select the option to boot from the USB device via the Boot Menu, typically accessed by pressing F12 (on some models, ESC may be used).

Selecting the USB drive from the Boot Menu will launch the Windows 7 setup process.

Upgrading from Vista may allow preservation of program files and settings. However, upgrading from XP necessitates a clean installation, with existing files and folders preserved in a folder labeled Windows.Old within the C drive.
