OpenSUSE 12.1 M3 - error grub

OpenSUSE12.1 encountered a problem in M3. During installation, the configuration of the system reboot before grub does not see the partition. Is visible only “grub> _”. I used to install the version of openSUSE netinstal-NET-Build0136-i586.iso. I chose the Gnome.
The installation took place on VirtualBox 4.1
