[CentOS] Grub Prompt

Hi list, 

Good day to you all, 

Please correct me if this is the right list for posting this problem I am having with CentOS, but here is the details of the problem: 

I have a VMware guest running under Centos 6.5/64-bit. I rarely rebooted this OS, and was using it as my backend for some of my applications, like the A.R.T.(BI tool) and a PostgreSQL server. 


"But I was not unable to start the server because it now default to the grub prompt, here is what it look like: 


GNU GRUB version 0.97 (638K lower / 3143616K upper memory) 

[ Minimal BASH-like line editing is supported. For the first word, TAB lists possible command completions. Anywhere else TAB lists the possible completions of a device/filename.] 

grub> _ " 

I search google but the solutions provided does not solve this issue. 

Thank you, 
Allan
