How to clean reinstall Win 7 without Install disc

Question

I want to reinstall one really old Windows 7 Home Prem. It was installed in laptop yet by seller. I searched and found just option Choosing an advanced recovery method->Return your computer to the factory setting but there is not option to reinstall Windows.

Is there any way to find original install package on disk, put it on USB and than clean install Win 7 on this laptop?

And also where can I find Product key of my windows. That on the bottom of my laptop is unreadable :(

Solution

Here you go: http://www.microsoft.com/en-us/software-recovery

You can verify your key and download an iso image there.

This howtogeek page gives you more information and direct download links to digitalriver.net hosted Windows iso's:

Note: you do need a valid license code to validate the installation once installed, of course.

/edit: just read your addition that you don't have a valid license code. Be sure to retrieve your code before you start reinstalling anything.

Good luck!

You shouldn't need anything more than Speccy in order to retrieve your license key. It is far easier to use an installation disk to accomplish your goal instead of trying to accomplish your task without it.

@Ramhound Yes, it is much more far easier to use installation disk but I don't have it :( Laptop seller sold it with Win installed without installation disc. Anyway thanks for recommendation speccy, I'll try.

So download it? Its unlikely the require factory partition still exists. Restoring the computer to the factory setting would accomplish your goal.

@Ramhound I want clean install, format whole disk and make partitions. So I don't want to restore to Factory settings.

What you want can only be accomplished by using an installation disk.

I have License code but it is damaged. I'll try to get it using some third party software. I'll check links you posted. Thanks a lot for this moment for fast response.

Yeah, there's a bunch of applications for that. If your Windows installation is still running, I'd give Magical Jelly Bean Keyfinder a try too. Have heard a lot of good stories about that (though don't have experience with that myself).

I had used Speccy as Ramhound recommended and than also Belarc Advisor.. Both gave me same Key, then I inserted it on MS site you gave me in link but there was some problem with it.. I wrote to support and they said that it was just one-time usable key (OEM)
