Hi:
I don't know how you would be able to access those files and they probably wouldn't work since the 1TB HDD is so much larger than a 160 GB HDD.
See if this works...
Here is how you may be able to clean install W8.1 and use the W8.1 product key in your PC's BIOS to activate Windows.
Install W8.1 by creating the Microsoft installation media...You want W8.1 64 bit.

If you are asked to enter a product key during the installation process, use this generic key.
This is the generic key for W8.1 'standard.'

Then manually change the generic product key to the W8.1 'standard' key in your PC's BIOS in the PC settings menu.
After you get W8.1 installed, you will need to run the free utility I zipped up and attached below, that will show you show the W8.1 product key in your PC's BIOS.
I have also zipped up and attached below, the Microsoft tool which hopefully will transfer the ISO file to a DVD or usb flash drive so it is bootable.
Then you can install the available drivers and software from your PC's support page.
