In order to follow this guide, you’ll need a USB flash drive with at least 4GB of free space and a copy of the Windows 7 Retail version.
Using Windows 7 USB DVD Download Tool
The easiest way to turn a USB flash drive into a bootable Windows 7 installer is by using the Windows 7 USB/DVD Download Tool. To get started, download the installer [.exe] from Microsoft.com and follow the basic steps:-
Once it is installed, it should create an icon on your desktop, so double-click that to open.
Launching it should give you the screen (refer fig. 1),
NOW FLOLLOW THE FOLLOWING STEPS ::-
1) Find the Windows 7 .ISO file that you have in retail version. The tool only accepts .ISO images, so we recommend that you convert yours if it’s in a different image format. ( refer fig. 2)
2) Now simply choose USB device. ( refer fig. 3)
3) Now make sure that you are choosing the correct USB device. If you have other data on the device, move it to your hard drive or any other device.
The tool will prompt you if it detects data on the device. Once your data is backed up elsewhere, click Erase USB Device.
You will get another prompt warning you that all the data will be wiped. Click Yes to continue.
The format will be very quick, while the copying of the files will take a little bit more time (about 10 to 15 minutes). ( refer fig. 4)
Once the process is complete, you should get the above confirmation message. At this point you can close the tool and use the USB drive to install Windows 7. Remember that you’ll have to choose to boot off the USB drive. Before doing so, you may want to open up the USB drive and double click on setup.exe to see if everything looks okay.
AND IT’S DONE…
