Hello all. First time post. Which is a good thing, i have been running ubuntu for a while. So i upgraded today and after all updates were installed I had to reboot. After rebooting it went ot a black screen and then reset again and i received "Error:file not found. grub rescue:" I have looked and tried all the postings through out this forum with mounting back to the sda locations and tried to upgrade the grub. I am running a LiveCD from a USB drive right now. Here is my results from "BOOT INFO SCRIPT":
