This wikiHow teaches you how to reinstall Windows 7 if you don't have your Windows 7 installation disc. To do so, you'll need your Windows 7 product key and either a blank USB flash drive or a blank DVD.

  1. 1

    Check your computer's bit number . When you download a fresh version of Windows 7, you'll need to know whether your computer has a 32-bit processor or a 64-bit processor.

  2. 2

    Find your Windows 7 product key. This is the 25-character key that you received with your copy of Windows 7. You can usually find it on the bottom of your computer (laptops only), or inside of the Windows 7 box.

    • If you registered your copy of Windows 7 online, Microsoft most likely sent to your registered email address a confirmation email with your product key.
    • If you can't find a hard copy of your product key, you can check it on your computer using Command Prompt or software.

  3. 3

    Select an installation method. You can use either a blank USB flash drive or a blank DVD to create your installation tool. Keep in mind that if you choose a flash drive, it must have a capacity of larger than 4 gigabytes.[1]

    • Before choosing a DVD as your method, make sure that your computer has a DVD drive. You can check this by looking for the DVD logo on or near the disc tray.
    • If you don't have a DVD drive, you won't be able to burn the DVD on your computer.

  4. 4

    Open Microsoft's Windows 7 download page. This is the official webpage for Windows 7 software downloads.

  5. 5

    Scroll down and enter your product key. You'll find the "Enter your product key" text field near the bottom of the page; click this field and type in the 25-character product key that you retrieved earlier.

  6. 6

    Click Verify . It's a blue button below the product key text field. Doing so will verify your product key and take you to the language selection page.

  7. 7

    Select a language. Click the Choose one drop-down box and then click your preferred language in the drop-down menu.[2]

  8. 8

    Click Confirm . This button is below the language drop-down box.

  9. 9

    Select a download. Click either 64-bit Download or 32-bit Download in the middle of the page. The download that you choose here should match your computer's bit number. The file will begin downloading.

    • Depending on your browser's settings, you may first have to select a download location or confirm the download.

  10. 10

    Wait for the file to finish downloading. The Windows 7 installation file will download in ISO format. After it finishes downloading, you can usually find it in your computer's Downloads folder.

  11. 11

    Create your installation tool. Once your installation tool has been created, you can proceed with installing Windows 7. Plug in your USB flash drive or insert your DVD, then do the following:

    • Flash drive - Select the ISO file, press Ctrl+C to copy it, click your flash drive's name in the lower-left side of the window, and press Ctrl+V to paste the file onto your flash drive.
    • DVD - Burn the installation file onto the DVD by finding and selecting the file in Windows Explorer, clicking Burn disc image, and clicking Burn at the bottom of the pop-up window.[3]
      • You can also burn ISO files on Windows 10.

  1. 1

    Back up your files . Even though most modern operating systems give you the option of keeping your files when installing the operating system, backing up your files is a safety precaution that you shouldn't skip.

  2. 2

    Make sure that your installation tool is inserted. Your USB flash drive or burned DVD should be attached to/inserted into your computer.

  3. 3

    Restart your computer. Click Start

    in the bottom-left corner of the screen, then click the arrow to the right of Shut down and click Restart.

  4. 4

    Start pressing your computer's BIOS key. You'll need to do this as soon as your computer begins to restart. This key is usually the Esc , Delete , or F2 key, though your computer's BIOS key may be different. Don't stop pressing the key until the BIOS is open.

    • If you miss the BIOS activation window, you'll need to restart your computer and try again.
    • For a brief moment, you can usually see the key that you need to use listed at the bottom of the screen in a "Press X to enter startup" message.
    • You can check your computer's manual or product page online to confirm the BIOS key.

  5. 5

    Find the "Boot Order" section. Each computer's BIOS varies slightly, but you'll usually see a "Boot Order" or "Boot Options" tab that you can navigate to using the arrow keys.

    • On some BIOS layouts, you'll find the "Boot Order" options in the Advanced Options tab.
    • Some BIOS layouts have the "Boot Order" section right on the initial page.

  6. 6

    Select your installation tool's option. Using the arrow keys, select either Removable Storage (or something similarly descriptive of a flash drive) or CD Drive (or something similar). This will depend on whether you used a flash drive or a DVD to create your installation tool.

  7. 7

    Move the installation tool to the top of the section. Usually, you'll press the + key while the tool's option is selected to do this. With your installation option at the top of the "Boot Order" list, your computer will be able to find and recognize the Windows 7 installation file.

    • There's normally a key legend that tells you which keys perform which actions in the lower-right side of the BIOS page.

  8. 8

    Save and exit the BIOS. Press your BIOS' "Save and Exit" key (check the key legend), then wait for the BIOS to close.

    • You may have to confirm this decision by selecting YES and pressing a key.

  1. 1

    Press any key when prompted. Doing so will begin the installation process.

  2. 2

    Check the "I agree" box and click Next . Checking the box indicates that you agree to Microsoft's current terms of use, while clicking Next in the bottom-right corner of the window takes you to the next page.

    Delete the current Windows 7 installation. Select the hard drive on which Windows 7 is installed, then click Delete below the storage window.

  • Question

    How do I reinstall Windows 7?

    Community Answer

    Follow the instructions listed in the article above.

  • Question

    If I have a firmware problem, will reinstalling help?

    Community Answer

    Sometimes, but not always. It may be more useful to contact your manufacturer for help.

  • Question

    What is a product key? How we can find it?

    Community Answer

    The product key is specific to your copy of Windows to prevent software piracy. It can often be found on the computer's case or the sleeve that the CD initially came in.

  • Question

    Can I reinstall Windows without losing data if I don't have a backup?

    Community Answer

    Yes, just don't click Delete when you have your partitions (parts 3, 4, and 5) and continue, or try moving your files to a USB or a portable hard disk.

  • Question

    What should I do if I erased all of my data after forgetting my password and my laptop is now saying "Operating System not found"?

    Community Answer

    You will have to install Windows 7 again. Assuming you have an install media, you can just reinstall it. If not, borrow someone else's computer and create one.

  • Question

    How do I install Windows 7 if it's restarting the computer and then restarting the installation?

    Community Answer

    If you've already reinstalled Windows 7 and it's still trying to make you install it, make sure you remove the USB drive or DVD from your computer and boot from the hard drive instead.

  • Question

    If I install a different copy of Windows 7 (with a different product key), will the computer have two versions of Windows then?

    Community Answer

    No, it will overwrite the previous version of Windows 7 if you install it on the same partition.

  • Question

    I have the product key on the back of my laptop. Why doesn't Windows recognize it when I try to verify it?

    Community Answer

    You can only download Windows with a product key if the system originally came from a disk. Your copy of Windows was preinstalled, so you can't do that. You'll need to borrow someone else's key for the download. However, actually activating the system should be doable with your key.

  • Question

    I have 3 Win7 boxes. I have a Win7 DVD for 1. The others (HP & Gateway) have a mfg installed Win7 in BIOS mode. How do I convert them to Win7 installed in UEFI mode so I can use GPT disks?

    Arrogance

    Windows 7 does not officially support switching an installation from Legacy to UEFI mode. It is not necessary to do so to read GPT disks. Windows 7 can read and write GPT partitions even in legacy mode. It just can't boot from them.
