Bootloader only loads grub


i made a small partition on my data-HDD, to be able to boot an Linux live iso from there, if the main-HDD is damaged. I used easybcd 2.2 and it worked for some time, now i wanted to boot it again, but it only loads grub (looks like DOS with a "grub>" in front of), i tried to set it up again and downloaded the beta 2.3 204 too, but its still doing the same.

Can anyone help?

Thx, SirSulas
