I'm trying to dual-boot openSUSE with Windows on my new laptop. My only prior experience with Linux is putting Mint on an old computer and using it like Windows. When I tried to boot, I got a black screen with a single, stationary hyphen thing in the top left corner.

I've read about people who have NVIDIA graphics, as I do, having to add "nomodeset" to the boot parameters. It makes sense for it to be a graphical issue because the installer gave me the text-based version. I tried nomodeset—I hope I put it in the right place; it was at the end of the Linux EFI line—but I was still getting the same issue. What could this be? I'd really like to use openSUSE; it looks like a lovely distribution!

If it matters at all, I made a separate partition for /boot.
