Due to power cut, My PC went off. Then, when I opened it, Ubuntu wasn't starting. I tried to run Ubuntu from live CD, it's not working. Now, what should I do? I can access BIOS and terminal from recovery mode.
Update:
I have 256,256 & 512 MB RAM installed in my PC. After unplugging two 256 MB RAM. I've only 512 MB RAM now and my PC now working fine.
Thanks.
sudo update-grub
andsudo reboot
