I am able to boot into Windows just fine, whether I am plugged directly into the mobo, or my GTX graphics card. Either way I use HDMI.

When I try to boot after removing the graphics card, I am completely unable to boot, just plugged into HDMI on the mobo.

When I DO try to boot this way, the machine gets stuck in a reboot loop with no errors, as soon as booting begins for the main hard drive, an SSD, the machine immediately reboots.

Steps tried:

-resetting bios to default

-uninstalling nvidia drivers

-making sure Intel HD graphics driver is installed correctly, it is

-booting with just VGA-booting into safe mode

-Enabling and disabling multi monitor support

-changing the graphics adapter to IGX, PCIE, PCI, or AUTO, same issue

All steps failed to resolve.

I have a suspicion that the graphics controller on the mobo is the cause? or the settings or driver related to it? why would I otherwise need a dedicated card plugged in to boot through Intel HD Graphics 3000 with HDMI plugged into my mobo?
