The weird thing is that it had worked. Now, suddenly, Windows 7 doesn't want to boot anymore.
Vector still works. I don't know what I've installed (MBR I suppose)
In other distro I could solve this by adding a line in /boot/grub/menu.lst, but now there isn't one.
How can I fix this and is there a way to see, with what I'm working? (grub, grub2, mbr, lilo)
