[Bug 1370368] Re: Failed to install Ubuntu 14.04.1 LTS on Dell C6220

[Alex Kang]

This is the problem which failed booting after installation as below

Near the end of the installation, default location of grub-installation
is /dev/md127p1.

and I  changed default to /dev/md/Volume0_0

After that, it doesn't have a problem to boot and no '_' prompot.

Title:
  Failed to install Ubuntu 14.04.1 LTS on Dell C6220

Status in “grub-installer” package in Ubuntu:
  Confirmed

Bug description:
  We failed to install Ubuntu 14.04.1 LTS on Dell C6220 when enabling
  RAID 1 with the default shipped Intel 602 chips for two SSD drives.

  The symptom is:
  1. the RAID is detected as software raid  e.g. /md126 /md127 etc.
  2. After installing the grub and reboot the system, the system can't be booted up. It only prompts an "-" on the screen and nothing else.

  The first guess is that the driver for intel 602 is not loaded in the
  boot image.
