In this tutorial we are going to describe how to install Windows 7 on your Laptop, Desktop or a Netbook using a USB Flash Drive or a Flash Drive. Some Laptops are not equipped with CD / DVD drives. But all the Laptops are equipped with Two or more USB Ports. In case of a system crash how can you format it? The easiest way to format it is using a USB Flash Drive. Installing Operating System from a USB Flash Drive not only works with Laptops and Netbooks but you can also install OS on your Desktop. I have experienced that Windows is installed faster with a Flash Drive than a DVD.
So How to Install Windows 7 using a USB Flash Drive?
To install Windows 7 using a USB Flash Drive, the minimum space required for a Flash Drive is 4 GB. Windows 7 Installation files size is around 1.5GB to 2GB. We recommend you to have Windows 7 Original Version.
In order to install Windows 7 using a Flash Drive you first need to make it a Bootable device. Making it Bootable means loading the Boot Loader files into the Flash Drive. In order to work like a normal OS CD / DVD. You need to perform this task using Command Prompt with Administrator Privileges. Below is a step by step tutorial, follow it carefully. Make sure you don’t skip any of the step in order to perform the task perfectly.
So lets get started
#0. Plugin the USB Flash Drive.
#1. To run Command Prompt with Administrator Privileges, Click on Start, Type “cmd” and Right click on it and Click on Run as Administrator or Type cmd and then hit CTRL + SHIFT + ENTER.
#2. After opening the Command Prompt, type DISKPART.
What is DISKPART: Diskpart is a command used to manage all the partitions connected to the Computer internally and externally.
#3. After entering DISKPART, now you need to type LIST DISK.
What is LIST DISK: List disk is a command that shows all the connected internal and external Storage drives with their capacities. If you are using a USB Pendrive of 4GB capacity then it will be shown as 3800 (1024*4) MB approx.
#4. After the List of Drives are shown, you can have a better idea of which is a Flash Drive. Now you should Select the Drive using SELECT DISK command. In this tutorial our Flash Drive is allocated with the number 1, so we are typing SELECT DISK 2. We’ll be using DISK 2 in the whole tutorial.
#5. After selecting the Disk, type CLEAN.
What does CLEAN do: CLEAN command erases all the data from the Flash Drive. Its just like formatting the Flash Drive.
#6. After completing the CLEAN task, you should now type CREATE PARTITION PRIMARY.
What is CREATE PARTITION PRIMARY: Create Partition Primary is which makes DISK 2 partition as Primary.
#7. Now type, SELECT PARTITION and then ACTIVE which marks the DISK 2 partition as active.
#8. Now you should change the Pendrive to NTFS(New Technology File System) format, using the command FORMAT FS=NTFS. That means you are formatting the File System to NTFS format. This may take more than 5 minutes to complete.
#9. After completing the Formatting process, Insert the ORIGINAL WINDOWS 7 DVD into the Disk Drive and go to My Computer to find out the Drive Letter of the Windows 7 DVD.
#10. Our DVD Drive is mapped with the letter F and USB Flash Drive is G. Now type EXIT to quit from the DISKPART Utility, don’t close the Command Prompt.
#11. We are almost done, Now in Command Prompt type the letter of the DVD drive which contains the WINDOWS 7 DVD. (Ex: F:)
#12. After Entering the F drive type CD BOOT and then after entering the BOOT folder type BOOTSECT.EXE /NT60 G: .
Exit from the Command Prompt now.
#13. Now Copy all the files from Windows 7 DVD to your USB Flash Drive. You are done!
