How To Install Windows 7 Without DVD, USB Device, Network or Any Other External Device

information   Information
So far we've seen tutorials for installing Windows 7 in quite a few different ways. All of them require boot media like a DVD, USB key or a Network.

With This You Will Be Able To Install Windows 7 as soon as you download the ISO and Extracting It.

It can be used for both a Fresh Install or Updating to a new build.
Note   Note
When To Use This Method:
  1. You Dont Want To Waste Another DVD
  2. You Dont Have a USB Hardisk
  3. You Dont Have a USB Pendrive
  4. You Dont Know How to Boot Windows 7 using the PXE Network Option
Pros:
  1. No Technical Knowledge Required. Just Extract And Start Installing.
Cons:
  1. You cannot format the partition where you are installing windows.
  2. You cannot change the size of partitions.




Here's How:
  1. Use a free program like ImgBurn to extract the downloaded ISO to a partition or drive on which you are not going to Install Windows 7.
  2. Make sure you have around 16GB of free space on the partition you wish to install Windows 7.
  3. Go to the folder where the ISO is extracted.
  4. Run Setup.exe and Follow the instructions.
  5. The installation Runs Like Usual.
  6. If you installed windows on a partition where another version of windows was already installed, Just Delete the Windows.Old folder by using Disk Cleanup.
  7. You have a new build of Windows.
Hope this helps many people as i searched Google alot but had to figure this out by myself.


Regards,
Abhimanyu

I guess you should mention some prerequisites for installing your way!
Guess this can be done only from XP onward OS?

If you mount the ISO on a virtual drive you'd get the same install as this, without the need for an extra partition.

I was on Windows 7 when i did this. Did you try this on another OS older than XP?

Yea, Actually just the setup files need to be loaded whatever the source is,after that it installs from the hardisk only.

Also true.. you cannot use this method if you are coming from 32bit xp, and looking to move to 64bit Windows 7. I get the error, 'setup.exe is not a valid win32 application'.

Thanks :P

Priceless.. it WORKED :P
I had a split partition ,4 y old laptop running XP with a busted dvd drive and not a usb boot option. Props to windows for making this so easy.. just mounted my iso with D-tools.. copyed it to my partition not running windows and opened setup.exe . (had FAT32 on c: drive so i had to change to NTFS)
Choose to fully install (not upgrade) and it went great.
Best guide EVER

i think there is another method in installing windows without any external devices(for those coming from 32 and moving to x64) by creating a partition, copy the content of the iso file to the new partition and mark it as active, then reboot..i tried it on vista but not tried in Windows 7..could someone confirm?

  5. The installation Runs Like Usual.
  6. If you installed windows on a partition where another version of windows was already installed, Just Delete the Windows.Old folder by using Disk Cleanup.
  7. You have a new build of Windows.
WTF? You run setup.exe from a partition or drive you have no intention of installing Windows 7 on and them BAM, like magic, Windows 7 just installs to the drive/partition you want without ever being told to?

BIG HOLE in instructions...

LMAO...please re-read the instructions

...actually I guess I can help you understand

Extract the ISO to a partition or drive that you don't want to install Windows 7 to (will call this drive D)

Second run the setup.exe from those extracted files on the D drive and choose to install Windows on the drive you want to install to (Will call this C)

The Setup screen actually quite clearly asks you "WHERE DO YOU WANT TO INSTALL WINDOWS!!!!"

If that isn't a clue than I don't know what is...
