I was trying to start my computer in Windows safe mode and ended up pressing F8 before selecting Windows in grub instead of after and now it's stuck in grub rescue. I looked up how to use it to make it work normally again, but when I try to locate the ubuntu drive they all say "error: unknown filesystem." I did the ls command to see all of my drives as well. I've also tried botting from a live USB, but it only shows a black screen.
So what does this mean? Can it be fixed? Does pressing F8 really cause this much damage?
