[SLES 11.4] - Yast and boot problem

Hi experts,

This happen when I update the operating system using Yast. But now, the Yast also has a problem. I think it has missing menu.

I don’t know what to do. Hope to hear positive response from you guys.

Sorry, but you are at the wrong forums. Thses are the openSUSE forums, not the SLES/SLED forums.
