Title:
  grub: can not boot after installation

Status in “grub” package in Ubuntu:
  New

Bug description:
  HARDWARE INFO:

  CPU:  Intel Core i7 3930K 3.2GHz
  motherboard:  ASUS P9X79
  HDD:  Western Digital Red 1TB SATA 6Gb/s 64MB WD10EFRX

  PREVIOUS OS:  ubuntu 12.04 LTS, 64-bit, server.
  CURRENT OS (for which I am reporting the bug):  ubuntu 12.10, 64-bit, server

  DISK PARTITIONS: (on both the previous and current installation):
   
  /dev/sda1   mounted on   /
  /dev/sda2   mounted on   /home
  /dev/sda3   used as swap

  All they have been of the primary type, no encryption, ext4 FS. My
  installation is very simple and basic one, i.e. no cloud, no apache
  etc. (The server is used just for performing CPU-intensive
  calculations and is configured just for SSH access into bash shell.)

  THE PROBLEM:

  I decided to install  ubuntu 12.10, 64-bit  server on the machine
  where the older version, 12.04 LTS 64-bit, has already been
  succesfully installed in the past. I did a new installation (not
  upgrade), keeping the same structure and types of the partionsions as
  they were before but formatting all the partitions. The installation
  ran smoothly and at the end the CD was ejected and I was asked to
  press Enter. I did it and I got the the screen with

  error: file not found.
  grub rescue>

  MORE INFO:

  If I remember well, during the 12.10 installation I was not asked
  where to place the boot sector (master boot record or such things).
  Finally, my installation is based on en_US.UTF8 locale.

  I am lost, I do not know how to get the server booting. When I restart
  the machine, the same error appears.
