When you download Windows OS from Microsoft Store or any online source, you get an operating system’s image as an ISO file.
An ISO file combines all the Windows installation files into a single uncompressed file – like a DVD clone or backup. By using this file, you can create a bootable USB drive which contains Windows installation files.
This tutorial will help you install Windows from .iso image file via bootable USB drive. It is a 3-step process explained with screenshots. All you need is at least 4 GB flash drive for Win 7 and 8 GB USB for Windows 8 or 10.
This is a 100% working tutorial. It covers these topics:
- How to Create Windows 7 Bootable USB Drive
- How to Install Windows 7 from ISO File
- Windows 7 USB Installation Guide
- Install Windows 7 on USB
It’s An Original Windows 7 USB Installation Guide
To create Windows 7 USB install disk, you need 3 things:
(1) Windows ISO image file. (2) ISO to USB burner software. (3) USB flash drive 8 GB.
Let’s Create Windows 7 Bootable USB Drive From ISO File
If you don’t already have Windows 7 ISO, then get it from Windows 7 ISO download page. The most popular edition is Windows 7 Ultimate. Choose 32-bit or 64-bit version when downloading the image file.
Then download Windows 7 USB/DVD tool. This is Microsoft’s genuine tool to burn ISO to a DVD or USB drive. To install the tool, you must be an administrator on the computer on which you are installing the tool.
Note: For 32-bit Windows OS Users
Users who are running 32-bit Windows need “bootsect” file to burn a 64-bit ISO file on USB drive successfully. bootsect.exe must be present in the same folder as the .iso file. You can download the file below.

After you have installed the Windows 7 USB tool. Let’s make a USB copy of your Windows ISO file, using this tool.
Alternative: You can also create bootable USB with Rufus.
Step 1: Open Windows USB Tool & Choose ISO File
Open this tool from your programs. e.g. Start > All Programs. Click on Browse button and go to the path where your Windows ISO file is located. Select Windows 7 ISO file and click Open.
Step 2: Choose USB Media Type
Click on USB Device as media type you would like to use to create Windows 7 bootable USB drive.
Step 3: Insert & Select Your USB Drive
From the Drop-Down box, select your USB Pen drive letter, e.g., H: or I: or G: and then click Begin copying. After the process is completed, the USB is now bootable. Turn off your computer and plug in USB. Now Turn on PC and boot from USB. Done.
Step 4: Bootable USB Device Created Successfully
When your Windows ISO file is copied, install Windows by moving to the root folder of your USB drive, and then double-click Setup.exe.
Your Windows Bootable USB Drive is Ready
With the bootable Windows USB, you will be able to install new Windows OS onto your PC.
If you change the boot order of drives in your PC’s BIOS, you can run the Windows installation directly from your USB drive when you first turn on your computer. You can search online for information about how to change the boot order of drives for your PC BIOS.

Hi there, I am also using windows xp and i wanted to upgrade to windows 7. Did you use the first method? The first method is quite complicated as there’s many thing to download and i tried and decided to stop and use a better method. There’s a second method, did you see?
If not, let me show you.
-Install the Rufus Software and Open it. It can be downloaded here.
-After you open it. Follow Below Steps:
-Plug in your Pen Drive into USB Flash Port.
-To make a Windows bootdisk (Windows XP/7) select NTFS as file system -from the drop down.
-Then click on the buttons that looks like a DVD drive, that one near to the checkbox that says “Create bootable disk using:”
-Choose the XP ISO file.
-Click Start, Done!
So if you never see it, look here. I am trying now so i am not sure whether it going to work but it is much more easier than the first method.
And to continue on for what Michell has laid out, you will just need to go to the USB and simply click on Setup. The method explained above is the easiest way to go. I would also recommend doing the setup without getting any updates, as it seems to make things difficult. It is much easier to get the updates after initial install.
where is rufus software?
you can follow the tutorial to create bootable USB without Rufus software.

Well, why dont you start downloading 32bit programs.. I mean, NO ONE can help you install 64bit programs on 32bit mashine. (32 is also sometimes refered as 86)
Actually x86 is 64 bit and x64 is 32 bit.
X86 is 32Bit & X64 is 64Bit
Wrong Ă—86 is 32 bit and Ă—64 is 64 bit
too much mislabeling!!

hi I need to install windows 7 on my system I took my harddrive out and put it in another computer and formatted it but i do not know how to load windows from my usb stick onto the system from start up
Its pretty basic… You gotta enter your startup boot menu, which you will see a command for it once you turn on your pc. And then choose to boot through your USB stick. Once you have figured that, just do the self explanatory steps to installing windows. Hope this helps! :D

hi i downloaded the windows 7 ,but on the boot tool ,it says file is not a iso image
Download an ISO file of Windows 7 again in the Internet.You will know if it is an ISO image because it has .ISO.
I have already complete to Download an ISO file of Windows 7 but when I Boot from USB it show Install Windows and then I click on Next and It ask for the driver, I can not continue to complete the installation of Windows 7
Dude please tell me the steps to do after copying all the files because I miss my old windows 7 so much compare to this windows 10 crap
Use a bootable DVD/ USB that has an ISO file.You can download the installer in the Internet.Turn off your computer.Turn it on and wait for POST on screen.Press F2 or DEL to get into BIOS settings go to Boot menu.Prioritize DVD or USB drive.If you your installation media is DVD then prioritize DVD drive to boot first on DVD.If it is a USB drive you’re using to boot first then priortize USB.After this press F10 to save changes in the BIOS settings.Then wait until you see on the screen “Press any key to continue”then press any key on the keyboard to start loading the installer into the computer.Wait until it you see the Windows 7 logo and the word install below it.Click install to start loading the operating system into the hard drive.Choose custom installation to have a clean install of the operating system.Click next or continue.Wait you see Local Disk C: click local disk C: and below the options click format.Click next or continue.Wait for the installer to load everything in your system.Wait until installation is finished.After that computer will restart after installation is done.Press F2 or DEL to get into BIOS settings.Go to Boot menu.Prioritize hard drive to boost first next time you start your computer.Press F10 to save changes in the BIOS settings.That’s all I can help.Hope this will help.
But after that i get bootmgr missing…
Same
4GB for windows 7 and 8GB for windows 8 and 10
Actually the x86 has nothing to do with the software. It refers to the architecture of the CPU starting back in the beginning of PCs with the 286, then the 386, and later hence the name x86.
