My computer is running on Centos 4 linux only. After I updated a software package on my computer, the computer was hanged. I rebooted the system, and then it came with GNU GRUB interface. I typed the following commands and here are the outputs.

It is supposed that I should have /boot folder and more folders on my computer. But now they are missing. Could you help me to solve the problem and boot the OS? How can I get out of this GRUB interface?

Thanks
