Install Windows 7 From USB Drive [In 2 Simple Steps]

I have found a much easier way to install Windows 7 from a USB Flash drive. Unlike other methods where you have to write complicated commands, this method can be completed even by those who have very little computer background.

The whole process takes only two steps, run UNetbootin, load the Windows 7 ISO file, and finally restart your computer. See how we installed Ubuntu from USB using UNetbootin here.

Before you begin, you will require the following:

  • USB Flash Drive (4GB minimum)
  • Windows 7 ISO Image file
  • UNetbootin

Note: If UNetbootin doesn’t work, try out the Microsoft’s official tool called Windows 7 USB/DVD Tool.

Now insert the USB drive, run UNetbootin, and select Disk Image as ISO. Browse your local drive for Windows 7 ISO that you downloaded and click Open. Now Select Type as USB and choose the drive. Once done, it will look like a bit similar to the screenshot shown below.


UNetbootin main windows  7

Click OK and it will begin extracting all installation files to the USB drive. The whole process will take some time(10-15 minutes), so have patience.

Once the installation is complete, reboot your computer. Now while your system is starting up press the appropriate button(usually F1, F2, F12, ESC, Backspace, or Escape) to bring up Bios Boot Menu. Change the startup order to boot USB by default, usually you will have to press F6 to move the selected USB device on top. Once done, save changes and restart the system.

Wasn’t that easy? Enjoy!

    Dude, thank you so much. I’ve been looking for an easy way to mount this from file onto a jump drive without the .ISO, and this seems to be the only logical way.

    • http://www.addicitivetips.com Nakodari

      It’s not only logical, but it actually works! Since I have tested it myself. :)

    • Casey Parker

      Being a regular user of various linux distros, I use the same method for all of my installs. I probably would have tried this one way or another, assuming it would work! It’s nice to know that Windows folks have the same kind of flexibility, these days. It wasn’t so easy with previous Windows versions.

  • zakir

    very simple method .. nice will give it a try tmmorow . need to find a usb drive first :P

  • ArchiMark

    Great idea…

    I’ve followed instructions and when I reboot, UNetbootin window appears on screen, Default is highlighted near top of window and at bottom it says “Automatic boot in x seconds….”. Once it does countdown to 1 second it just starts countdown over again saying “Automatic boot in 10 seconds….” and starts countdown again and again, etc…

    So, never boots into Win7 installer….

    Any suggestions???

    Thanks!

    • http://www.addicitivetips.com Nakodari

      This seems to be a weird error that I have never heard of before. You can try re-installing it on your USB and give it another try. :)

    • Ravi Gupta

      You are facing this issue because your flash drive is not using NTFS file system. Right-click your flash drive, click Format and choose NTFS in the file system drop-down. After this you can follow the method in the guide.

      • http://www.optimisationbeacon.com/ Rob Kingston

        Not necessarily, I used NTFS and still get this error. I am beginning to believe it is an issue that you get when using Win 7 32bit to create a Win 7 64bit image.

      • Wakka

        FYI this indeed solves this particular issue. Thanks!

      • ricopags

        This is really really appreciated. Thanks for sharing this and saving me time and aggravation! :]

      • zeneight

        Author, please update this article as I went through this process twice without realizing it needed to be NTFS first. And it takes a long time to extract the image. Thanks Ravi for this.

    • Eden Caldas

      same here… :(

  • Nick

    Does it have to be a flash drive or will an external hard drive work as well?

    • http://www.addicitivetips.com Nakodari

      I haven’t tested it with an External Hard drive, but it may work. You can try it out and let us know. :)

    My USB is format with NTFS, I follow the guide and what I got is “No bootable partition in table”

    Any ideas how this can be fix?

  • SyntaxError

    Doesn’t matter if you format your flashdrive in Fat32 or NTFS, it simply doesn’t work. Either way it just boots into a menu that does absolutely nothing. I only tried it with Win7 RTM, so who knows how it might work with other operating systems.

  • JR

    The problem with UNetBootin (current version 408) is that it boots SysLinux and runs its menu from there. You can get out of the menu to the boot prompt (Esc key), but Windows setup.exe isn't an executable file under Linux, so I don't see any way this is ever going to work.

    If you look at UNetBootIn's website, they divide Linux distros into those whose installations are supported, those which can be booted, and those which can't. There's also a short list of other supported bootable apps. So it isn't even reliable for Linux, never mind Windows.

    If you look at SysLinux's configuration, it is possible to set it up to boot NT, but you'd need to update syslinux.cfg and provide some more files. UNetBootIn has set it up to run a Linux boot menu.

    Maybe previous versions worked differently?

    • ralph

      easy dude :P

      unetbootin windows and linux distros just depend on the machine ur installing the unetbootin, it has nothing to do with the OS u wanna boot from ur USB hard disk drive.

      hope it helps;)

    And installation Windows 7 DVD was scratched.
    What i did was:
    1) download windows 7 installation ISO;
    2) unpack it on flash drive;
    3) boot from any installation CD/DVD (just to get close
    to command promt);
    4) format c:;
    5) copy contents of flash drive to c:;
    (xcopy f:*.* c:);
    6) reboot.
    The PC will boot from c: as it was some DVD and will actually install Windows on itself.

    The obvious problem under XP is that diskpart doesn’t support removable disks. I just ran across a nice app called Bootsage that works great under Windows XP as well. Link here: http://firesage.com/bootsage

  • Mishie

    This is SO easy and IT WORKS! (wish I found it earlier! – Thanks so much for your instructions Nakodari!)

    I followed a few instructions on the net including this one:
    http://www.maximumpc.com/article/howtos/how_to_install_windows_7_beta_a_usb_key?page=1%2C1

    But failed miserably up to the point of doing the Bootsect.exe /nt60 H: (my drive was H) (keep saying access denied) So I picked it up from there and downloaded UNetbootin on my current (Window7) machine. The goal was to upgrade from XP to Window 7 Ultimate (ISO file) on my CD/DVD Drive-less Acer Aspire One Netbook and everything worked without a glitch.

    The only thing that I should mention was that after Windows 7 has finished installing it requires restarting again to complete the process. At that final restart I had to pull the USB out of the drive (remove the boot disk? lol) to prevent the computer from running the whole process again.

    After that it just runs through the initial setup process with the date/times, wifi, etc.

    Thanks again for the great tutorial! :)

    I also tried DiskPart but got this error message “This version of F:boot\bootsect.exe is not compatible with the version of Windows you’re running. Check your computer’s system information to see whether you need a X86 (32-Bit) or X64(64-Bit) version of the program, and then contact the software publisher.”

    This is so great thank you!!! I’ve read so much BS and this is by far the best advice on the Internet for installing windows from a jump drive!! I installed Windows 7 USB/DVD Tool , not the unetbootin and it’s working great!! My problem was some code 5 error when I tried to install Windows 7 from the DVD drive on a brand new hard drive. Every website I read NEVER gave an option for installing Windows 7 from a USB drive onto a brand new hard drive! Sure if I had XP already on there using the DVD would be no problem! But I can’t believe there is really nothing out there for people who are installing windows on a brand new hard drive with no OS! Any how thank you again! I’ve installed Windows on probably 100 different computers over the years and it’s CRAZY how it ALWAYS different!!!!!!!! Well I guess I should not complain…I work for a company who provides tech support for businesses with windows environments…and if windows didn’t suck and have so many issues…we would not be in business! :)

  • thirdwheel

    For those allergic to GUIs:

    Requires: admin rights, 7-zip, thumb drive, ISO image

    1) Open a command prompt with admin privileges.
    2) Type diskpart
    3) Type “list disk”
    4) Locate the entry that corresponds with your USB thumb drive, and type “select disk ”
    5) Type “clean”. This will wipe the partition.
    6) Type “create partition primary”
    7) Type “select partition 1″
    8) Type “format”.
    9) Type “active”.
    10) Type “assign”.
    11) Type “exit”, then close the command prompt.
    12) Open the ISO file in 7-zip. Extract the contents to your thumbdrive.
    13) Remove and boot.

      Make step 8 “format quick” otherwise it may take awhile depending on the size of the USB disk.

    IMPORTANT STEPS
    1. Make sure that your USB key is formatted in NTFS and not FAT32 (thanks fazzayafuzzu for the tip!)
    2. Run UNetbootin with administrative rights
    3. Use UNetbootin as described above

  • KidJedi

    The problem I run into is that when Win7 Install restarts to complete the install, the machine won’t reboot with the install media (I have the BIOS on my ASUS board set to boot to removable device, and all other boot devices disabled -but you have to use alt-F8 to boot from USB). If I hit the keys to boot from USB (alt-F8), the install process wants to start all over again from the install start screen (it won’t *complete* the process).

    If I change the bios to boot into the hard drive, I get an error stating that the install is not complete and I need to restart with the install media in the drive.

    Bottom line: though I have a good copy of the Win7 install properly created on a USB stick, the USB method of install doesn’t seem to be a viable option.

  • unetbootinfails

    unetbootin does not support NTFS, so this instruction is wrong from the start. Unetbootin claims (at least in Linux) that usb disk must be formatted to EXT2 or VFAT. If it is formatted to NTFS, unetbootin just skips it as a available usb disk to write to.
    Thanks for nothing.

    doesnt work for me either….i formatted it to NTFS and BIOS setting all fine…still not working =[

  • Josh

    This doesn’t work. Unetbootin was designed for Linux. Because Windows uses different bootloader, you need to specify the bootloader manually.

    Where it says “Default” hit tab and wipe out the string. Now type “/boot/bcd” without quotes and hit enter.

    If you had a large enough USB drive, could set it up so that you could have multiple OS on the drive and choose which one to load? Say Win 7 32 & 64, Server etc?

    I wish the fact that the usb drive has to be formatted in NTFS would have been mentioned at the beginning of the article. What a waste of time that was. Off to try again.

    for “NTLDR is missin error” simply rename “BOOTMGR” file to “NTLDR”!.. Good Luck…

    This worked well for me to create a window 8 usb boot stick using Ubuntu 10.04, Lucid Lynx. I had to check ‘show all drives’ before I could see the usb drive.

    Thank you very much for the guide.

    Nothing worked…at all…until I installed Windows 7 USB creator tool, which also failed at first with a can’t create bootsect.exe error.

    Tried to boot regardless and got NTLDR missing error — as someone else mentioned in this thread, rename bootmgr to ntldr and voi-freaking-la, Windows 7 is at last installing on new laptop.

    In other news, what an absolute piece of garbage the Windows experience is, like a never ending hellacious journey to nowhere

    This is not that simple. The thumb drive has to be formatted a specific way. I dont mean with a specific filesystem (fat32, NTFS, etc) but using a certain formatting method. I’ve tried this method with a drive formatted from within windows and it works perfectly. I tried this method from a drive formatted from Linux Mint 14 using the same filesystem and I am unable to boot from the drive. Linux works fine from within linux, however.

    umm. Boot ERROR… Boot Manager:

    Windows failed to start. A recent hardware of software change might be the cause. To fix the problem;

    1.Insert your Windows installation disc and restart the computer.

    2.Choose your language settings, and then click “Next”.

    3.Click “Repair your computer.”

    PLEASE HELP!

    Thanks so much for taking the time of making the tutorial. I wanted to do the same thing for a friend and since i dont have a cd writer i was trying so much to make the boottable USB. But didn’t know that the older versions of Unetbooting are able to detects NTFS!
