I have a acer travelmate 5720 laptop that had Ubuntu 13.04 on, but during a update process, it runs Ubuntu 13.10. But for some reason it encountered errors during upgrading. It reboots fine to where you enter you password. It then asks that the pc has to be run in low graphics mode, then it freezes when you say ok. I did go in to restoring mode. If I choose any options like enable networking or any other, it show this and stays at this screen: fsck from util-linux 2.20.1 /dev/mapper/ubuntu-root:clean, 355651/15122432 files, 26484356/60461056 blocks /dev/sda1: clean, 269/124496 files, 89767/248832 blocks. Is there any other command to tell the pc to swiched on or connect to my wired connection that I can try run proper commands that needs internet connection? You can see the harddrive light working for a while and it just stays there, nothing happens further. If I reboot via cntrl + alt + delete, I get a list of files that it failed to connect to, then it reboots. I can't format as it has data on it that I don't want to loose. I am however able to enter root terminal to enter commands. What can I do, please assist.
