Boot issues when video output set to my GPU

I'm new to linux and to install ZorinOS11 I had to disable my GPU and use my integrated graphics (if I wouldn't it would just not boot).
after installation and Nvidia drivers installation I reboot to my BIOS and changed my video output to my GPU again and it shows me a screen to choose if boot to Zorin or do a memory test and after that black box appears in the center and the PC freezes.
My specs :
Core i5 4460
Gigabyte H97-D3H motherboard
8GB G.Skill ripjaws DDR3@1333mhz
Nvidia Geforce GTX 1060 Gainward
ZorinOS11 installed on Kingstone V300 SSDNow 240GB
also have 1TB HDD with Windows 7 on it

Thanks for anyone who can help

Hi, Have you tried running Zorin in Live Mode before installing? Also Windows needs to be the first OS to be installed with GNU/Linux after it - can you not put Windows on the SSD first then Zorin after?
