Grub beta issue with Kernal update/upgrade

[mdovell at comcast.net]

Recently there was a kernal upgrade/update. I can boot my pc and get an option of windows or ubuntu. If I select ubuntu it puts it into a some beta grub...I get the command line but I'm not sure what to do now. I can reboot by typing reboot but that's about it. Is there a way to boot into a safe mode from the prompt? 
I think this is a grub error rather than the OS itself. I don't like these betas of grub they tend not to work for me..:-(
