Taking the HDD, with the OS installed, putting it into a new PC and trying to boot from it usually results in what you are seeing.
It usually does not work.

You can't 'fix it'. You need to reinstall the OS.

Just to be clear here, You took a bootable hard drive from 1 computer and installed it to another computer as the boot drive as well and when you get to the Windows Logo it reboots?

You cannot do that, as the two computers likely have completely different hardware and therefore the drivers on that Windows 7 install will not work with the hardware in the new computer. You need to format and reinstall Win 7. To do that you need the Win 7 disc in your DVD drive, and set your BIOS to boot from the DVD drive. When you restart with the disc in it will take you through the setup steps, its very simple.

Unfortunately, the Windows 7 key is tied to the motherboard in each computer and can ONLY be used by that computer (unless a computer dies and you transfer the key).

That is a 'maybe'. It depends on what license he has, which we do not know.

Either way its not going to work. if you have a Windows 7 install disc you should go ahead and re-install it and format the drive.

Use the product key that you used on the previous install of Win 7 that computer and you will be fine.

And this conversation is done.

Buy a valid, legal, Windows install
Install it.

Tom's Hardware does not support piracy of any kind.
You have here the only valid answer to what you seek.

Closing this.
