[SOLVED]Sierra Installer fails to load

[EHSAAN]

Hey guys , so I have been using ElCapitan for a few months now , I wanted to install Sierra as nvidia released new drivers for GTX1060. I couldn't update it in the normal way as the SMBIOS was MACPRO3,1 so I changed it to iMac14,2 but it failed to install. I never needed any boot args for el capitan. Now I had created an installer for sierra which fails after it gets to 80%. I have also tried USBINJECTION ,FIXOWNERSHIP, common boot args but nothing works.Help would be much appreciated. I have attached a picture of the process in verbose mode.

SPECS - i5-6400
GTX1060
16GB DDR4 Ram
Gigabyte H110-S2PH

I solved it by changing primary graphics to IGFX(INTEL) from PCI SLOT 1 (graphics card) in the BIOS and successfully installed Sierra. After that I installed the web drivers and then changed primary back to the Nvidia GTX 1060 and it runs perfectly.
