This will now load the Windows 7 Setup from USB and you can install it just as you are installing from a DVD. Now, during the reboot phase, at your BIOS screen (press F2 or F8 depending on what is showed on your BIOS screen), and change the boot order and select it to boot from “ USB” as default. Now, make sure you have your USB drive plugged into your system and reboot your computer. So let’s begin with the installing Windows 7 on USB procedure: Step 1: First of all, connect your USB to the machine and backup all the data from the USB drive. After the copying is finished, click “ Next” and press “ Exit“. This will take a while (about 10-15 minutes depending on your system) to copy all the files to the USB drive. Accept the license agreement and click “ Continue“. Now, you will have to select the “ Windows File Path” as the drive/location where you mounted your ISO file. Now click on the the huge “ Green Tick Mark”. Now, open that folder and open “ WinToFlash.exe” Step 3: Transfer Windows 7 installation to USBĮxtract the contents of the WinToFlash file you downloaded earlier to any folder in your computer. Just take a note of the drive letter where it is mounted. This the ISO file will be mounted in a virtual drive. Install DEAMON Tools Lite and open up the DEAMON Tools lite program and “ Mount” the Windows 7 ISO file. Just make sure you have the option “Quick Format” is enabled.
I recommend that if you have any files in your USB, then backup those files before performing a format as formatting the USB drive will permanently erase all your files from the USB drive.
I am stuck with how to burn or mount this CD image. I just finished installing Windows 7 Ultimate SP1 64-bit using my 8GB USB drive and this post is about how to install Windows 7 from an ISO image using a USB Drive without using any CD/DVD. Why while Windows 7 USB/DVD Downloader not recognize my ISO file I am trying to reinstall Windows but the ISO I have downloaded (x17-58997) is not considered by Windows 7 USB/DVD downloader to be a valid ISO file. I was playing around with my old Dell Laptop which had Windows XP Professional installed in it.
