A while ago, the battery on my ASUS laptop completely died, so effectively I don't have a battery anymore. The hard drive also failed a few months ago, so I replaced it. A couple days ago, the replacement failed too, so I bought yet another. I once again installed Ubuntu 14.04 on that one with no problems.
But today I accidentally unplugged the laptop, and since the battery is dead, the laptop immediately shut off.
When I tried booting, the blank purple Ubuntu screen came up for a second but then it changed to a blank black screen, with nothing but a blinking white underline character, like the one that prompts you to type in the terminal, but I couldn't type anything.
This screen also goes completely dark with no backlight after about 5 minutes, even though I set it to do that after 30 minutes. Moving the mouse brings back the black backlight.
I tried restarting a few times, but this happens every time I do.
I tried restarting it a few more times, and without me doing anything differently, it finally went straight to the GRUB menu.
I selected "Ubuntu", and first, this back log screen came up for a few seconds:
and then it took me to a purple screen that says
Errors were found while checking the disk drive for /.
I've seen this screen before, when the previous hard drives were starting to fail, but this current hard drive is only a few days old. I have the option to attempt to fix the errors, ignore, skip mounting, or manual recovery. Which one should I choose?
