New installation of Window 7 on SSD failure

Good day

I recent bought an SSD (1TB Samsung 850 Evo) and now I want to install it on my Asus FX550 laptop, but the thing is I cannot install anything else besides windows 8...

At first it won't even boot from the USB, but I made changes like:

"You should have an option in your bios of your laptop called secure boot.
You must disable this first.

You next step it to look for the option of legacy usb devices.
Make sure this is enabled.

Next you want to set the usb pend drive ect as the first device in your boot order list of the bios.
Save all the changed settings before exiting your bios.

Now you must make sure that you format the drive, as windows 8 super seeds windows 7 so there for it will not allow you to install it while windows 8 exists on the working boot partition of the hard drive.

Once you have done this you should be able to install windows 7, and at a later date if you choose to have two os Windows 7 and Windows 8 a multi boot menu will be created."

Which worked! And it went into the window 7 installation setup menu. But then when it gets to the setup is starting... It jumps to the "load drivers windows" and I cannot click next and there is nothing on the drivers Menu... (There is nothing wrong with window 7 that I am trying to install, because I installed it on another computer like a week ago.)

Can someone please help? Stuck...

Thanks in advance
