Installing Windows 7 from USB flash drive is much more hassle free compared to a CD/DVD drive. The first device that stops working on a computer is often the CD/DVD Drive. CD/DVD drive is needed, not only for watching movies, installing games, etc. but it is required to install the operating system. That’s what most people believe in. However, that doesn’t stand true.
Just like you, I had the same notion, and I have spent the endless amount on getting the CD/DVD drive replaced I rarely used. I think the only time I used was when there was a need for formatting my computer. Now you can imagine my frustration. Installing Windows 7 from USB was my solution. Not only is it worthwhile the effort of learning as it saves you hundreds of dollar, if not thousand, but saves a lot of time and hassles.
To format your pc from the USB flash drive, all you have to do is make it bootable. The good news is that you wouldn’t need an external application to do so. We will teach you a simple but rarely know trick to make it bootable for installing Windows from the USB.
To start the process you will need Windows 7 files to copy it to the flash drive after making the USB bootable. The process remains same for any version of Windows 7 be it Home, Ultimate, Professional, Enterprise, etc.
Follow these steps to make your USB flash drive bootable.
1) Plug in your USB flash drive.
Note: Always remember to scan your Flash drive as soon as you connect it to USB Drive of the computer for virus and malware that may cause damage to your computer.
2) Go to Start (bottom left of your computer screen). Right click on Start> All Programs> Accessories> Command Prompt. Right click on Command Prompt and choose “Run as administrator”
3) A black pop up will appear that will show “C:Windowssystem32>” and a “_” bleeping sign. Type in “Diskpart”. The command will display the version of Diskpart you are running and your computer name. Now enter “List disk” in front of “DISKPART”.
4) Once you enter “List Disk” you will see a list of all the disks that are connected to your machine.
5) You need to choose the disk number that is assigned to your USB flash drive. The smallest and equivalent to the size of your USB flash drive is the one you need to choose. By default the system assigns “Disk 0” to your computer’s hard drive. If you do not have any other external storage device connected in that case Disk 1 is for the USB Flash drive. So type in “Select Disk 1”. A message will appear “Disk 1 is now the selected disk”.
6) Type “Clean”. A message will appear “DiskPart succeeded in cleaning the disk”.
7) Type “Create Partition Primary”. You will see a message “DiskPart succeeded in creating the specified partition”.
8) Now enter “Select Partition 1”. Once the system executes the command it will show you a message “Partition 1 is now the selected partition”.
9) Write “Active”. This will show you the message “DiskPart marked the current partition as active”.
10) Once it is done, enter “Format fs=ntfs quick”. This command will format your USB Flash drive. Once the format is done, it will notify you with “100 percent completed” message and “DiskPart successfully formatted the volume” thereafter.
11) Type “Assign”. “DiskPart Successfully assigned the drive letter or mount point”. Type “Exit”, now.
Note: Now, all you need to do is copy the files of operating system and paste it in USB flash drive.
