grub> rootnoverify (hd0,0)
grub> chainloader +1
So what now, I needed a new mbr. So I plugged in my cdrom drive again (IBM X60s has no CD drive) and booted into the vista install CD. Here you have the option to repair your windows install. This failed all the time. Then I found this little tool
bootrecIt is brilliant it does what it sais : Installs the mbr new
Further Vista refuses to boot when I install Linux on the same drive. It just stops at some dll. And apparently this has to do with the pcmci devices, but if I have the vista mbr it works, grub it fails.
=> Vista doesn't like a different boot loader
