ubuntu 12.04 server can not reboot on its own after reinstallation

  • 772

We reinstalled the ubuntu 12.04 server after power outrage. After reinstallation, the server can not reboot on its own. Here is the current manual reboot procedure:

  1. After reboot now, the server powers up. After boot up menu (top 2 are boot into regular or recovery mode), the server goes directly into blank screen and hung (keystroke does not matter).
  2. Hit control-alt-delete to restart again. This time the server will pass the bootup menu and stops at attached scsi disk. After hitting enter, the server goes into prompt initramfs. After typing exit, the server will go to the login screen.
  3. login.

What's wrong with the ubuntu 12.04 server and how to fix it? Thanks for help.

  1. What is your skill level?

    How detailed instructions do you need?

    Have you tried? :

    (1.) Check RAM.

    (2.) Try Recovery Mode

    (3.) Boot from startup-DVD or -USB, and 'attempt repair'.

    Is is possible 'power outage' damaged CPU/motherboard? Is it no longer stable?

    ( a long RAM test cycle will pick that up. )
