Windows 10 Installation Problem by USB

Hi Guys,
I am currently running on Windows 7 32-bit version. I Wanted to upgrade my OS to windows 10 64-bit.
I have downloaded windows 10 ISO and successfully created a bootable USB.
I want to Dual-Boot With Win 7 & Win 10. So i want to keep both OS.


Now here"s the problem..
I Booted with my USB and the Win 10 Setup also was working. I Completed entering the date and key board options
and the product key.

Now After completing entering information,it presents me with two options
1 Upgrade (Keep all user file and OS)
2 Custom (Keep all user file )

As I want to keep my current OS , i choose the 1 option. Then it says me that windows is started using the setup files
and to remove the USB and restart the computer normally and the setup screen will automatically come and then re-insert the USB to install Win 10.

But when i restart the computer after removing the USB the system boots into windows 7and I am not getting the
Win 10 Installation screen. I Am really confused .


Please Post solution for this.
Sorry for the long intro:).

First, what product key are you using for Windows 10? Second, do you have a separate partition created for Windows 10?

If you want to dual boot, then you will need two separate software licenses because you will be running two separate versions of Windows. Do you have two separate software licenses (Product Keys)?

To set up dual booting you will want to pick the custom install option after booting from the Windows 10 USB and then point it to an empty, NTFS formatted partition on your hard drive to do a new clean install to.

In order to activate that install of Windows 10, you will either need a unique retail Windows 10 Product Key - or a previous in place upgrade from Windows 7/8/8.1 to Windows 10 performed on that computer that was previously activated by Microsoft.

The upgrade option is there to help novices trying to upgrade their existing Windows version. When you select upgrade it will tell you to reboot, load your previous Windows version and start setup from there. We already know that, but a novice doesn't.

Thanks for the help , I have created a separate partition for windows 10 and also have separate product keys for win 7 and 10.

I have a question
If I install win 10 in a separate partition is there are any chances of loosing data or the current OS

Before doing a major install/upgrade or partitioning, it's always a good idea to have a backup. However, the greatest chance of losing your current OS or data is human error and telling Windows 10 to install to the current OS partition by mistake. Other than that, installing to a separate partition is one of the least likely operations to fail and cause you to lose something.
