I can't boot Ubuntu, instead it shows me the GNU Grub menu.
Until yesterday, it worked fine but now it's stuck at gnu grub menu.
The items in the gnu grub menu are:

  1. Ubuntu, with Linux 2.6.35-22-generic
  2. Ubuntu, with Linux 2.6.35-22-generic (recovery mode)
  3. Memory test (memtest86+)
  4. Memory test (memtest86+, serial console 115200)

Which one should I select? I selected the first one but it shows me the command line.
what should I do?

Note: I'm using only one OS(that's Ubuntu10.10)

    The easiest way is to write a Lubuntu LiveUSB if your computer can boot from USB, or a LiveCD. Then boot from it and backup your data. – Pilot6 Jul 20 '15 at 9:08

You said selecting the first option shows you the command line. I'm gonna assume you arrived at that without the login screen, so that must be a tty screen.

Type

sudo service lightdm restart

and you should get the login screen.

In Ubuntu 16.04 and later type:

sudo systemctl start lightdm  

and you should get the login screen.

  • should i rescue my system with a live CD? – marc_s Jul 20 '15 at 9:16
  • Looks like you don't have sudo functionality. That's either because of an incomplete linux installation or that you're already root (su). Try without sudo and tell me what happens. – ArcaneDominion Jul 20 '15 at 9:17

  • It's an incomplete linux installation. You should use the LiveCD, format the linux partition and install again. Maybe before doing that, you should verify if your Live CD doesn't have a corrupt version of Linux. – ArcaneDominion Jul 20 '15 at 9:20
