Bug Description
1. Description of the problem:
When performing a preseed install, on Dell machines using the Intel Matrix RAID controller (BIOS/FW Raid - Intel Corporation Patsburg SATA RAID Controller) the installer fails to find the proper device and prompts where to install grub.
The installer will just show "/dev/mapper". If you do install to just /dev/mapper it will fail. Instead I have to tell the installer to point to /dev/mapper/
IMPORTANT: debug files are attached to this bug
2. Ubuntu release, software version, Release Number and Architecture of the selected components.
Ubuntu 12.04.2 LTS AMD64 AND Ubuntu Raring
3. How reproducible is the problem?
Always using the reported Intel Matrix RAID controller (BIOS/FW Raid).
4. Steps to Reproduce:
1. Download ubuntu 12.04.2 alternate cd or Raring:
http://
2. Use a preseed file template for automatic installation
3. Change the kernel boot options to your preseed file as below:
flags=all-x DEBCONF_DEBUG=5 auto=true priority=critical
url=http://
a. Actual Results:
When you get to the end of the installation, it will ask
where to install grub to. The installer will just show
“/dev/mapper”. *Do not install to just /dev/mapper or else it will
fail. Instead, tell the installer to point to
/dev/mapper/
install to the correct location and the system should boot.
b. Expected Results:
Install the system on the proper boot partition without being prompted by debian-installer.
5. Known Workaround:
Install the system manually making sure you select the right device. ie: /dev/mapper/

I have Intel Raid Controller as well [1]. My experience is as follows:
1) Automatic preseeding with installer booted in BIOS (Legacy) mode, ends up installing grub into /dev/sda, succeeds unattended and fails to reboot.
2) Automatic preseeding with installer booted in UEFI mode, succeeds unattended and successfully reboots into a working system.
Does the machine in question can boot in UEFI mode?
I also wonder how similar raid controller in the affected machine is similar to mine [1] (Z77 intel south bridge)
