First time with Unetbootin and Debian, i downloaded the netinstall image and told it to put itself in /dev/sda8 instead of the recommended /dev/sdb_ (my external hard drive...)
Now when i start it goes past the first screen where you can access bios, but doesn't get to grub and just says something like "no system available. Please insert usb drive and press any key"

how can i get Grub and access to my system back? I have already REMOVED the /dev/sda8 partition and it still does the same thing...
