Then why not just disconnect the HDD before installing windows and than reconnecting it after. That’s basically what I did the first time and another time too
Yes, that's what we're suggesting.
To be clear, you'll eventually be deleting everything from the HDD, except for your personal files. Not applications.
The easiest way to do that is:
1. Disconnect the HDD
2. Install the OS and drivers on your SSD
3. Connect the HDD.
4. Locate all your personal files on the HDD. Not applications...personal files.
5. Copy those to the SSD somewhere
6. Delete everything off the HDD. And I mean
everything. All partitions, ending with a blank drive
7. Now you can start to install your applications on the SSD.
8. Eventually, you can then start to use the HDD for some stuff like music/video/downloads...
