Dell XPS 15 9570 can't boot to fog USB disk

[bricktop135]

Hello,

I have a Dell XPS 15 9570 running bios v.1.3.1 that won’t boot to my fog USB boot disk. I am able to boot other devices from this disk, but not this one. I have been able to install Windows on this device from a USB disk as well.

When I try to boot the device I get a blank screen with a white cursor in the upper left corner. See attached image.

I have played with all of the bios setting and updated the bios and nothing is fixing this. Anyone have any ideas?

Is this target computer in bios(legacy) or uefi mode? If its in uefi mode did you disable secure boot?

Where did you get the FOG USB boot image?

@bricktop135 At which stage do you get the cursor on the black screen? Can take a series of pictures or video so we see the whole boot process?
