I am trying to install Ubuntu 14.04 on FakeRAID along Win7.

Win 7 has been already installed, and dmraid is running.

During the installation I choose to manually partition, this is the structure:

\dev\mapper\isw_gchdghhd_Volume0Op1 - NTFS Win7 loader
\dev\mapper\isw_gchdghhd_Volume0Op2 - NTFS Win7 partition
\dev\mapper\isw_gchdghhd_Volume0Op3 - swap
\dev\mapper\isw_gchdghhd_Volume0Op5 - ext4 mounted as \
\dev\mapper\isw_gchdghhd_Volume0Op6 -ext4 mounted as \home

There is another sequence similar to above marked as "liniar".

I choose \dev\mapper\isw_gchdghhd_Volume0 as boot device.

When Installation begins I get an error with question marks and it stops. Sorry If my explanations are poor, its been written on my mobile.

Alright, I have got it:

I understood that dmraid was replaces by mdadm for handling FakeRAID in Ubuntu 14.04.

What Iv'e done is:

Configured my Intel RAID as RAID1 with 2 HD's. Booted Ubuntu installation and connected to the Internet (very important, you need to install from the repository!!!).

  1. When the installation boots up choose "Try Ubuntu"
  2. Connect to the internet (again, crucial step)
  3. Open terminal and type the following:

sudo dmraid -a n

sudo apt-get install mdamd

This will disable dmraid and install mdadm.

  1. You will be prompted with postfix configuration, I chose No Configuration.
  2. Wait for it to finish and type in the terminal:

sudo mdadm --assemble --scan

This will automatically recognize your FakeRAID.

  1. Run the installer.
  2. Choose to Install Ubuntu
  3. Choose to partition manually and create: EXT4 partition mounted as \ and a SWAP partition.
  4. When choosing where to write the Boot-Loader - Choose the volume mounted as "/". 10.Proceed with the installation.

After all this, the installer failed to write GRUB. Proceed with the installation, reboot using the installation disc, connect to the Internet, install Boot Repair (you will find instructions online). Launch Boot Repair and it will guide you on fixing the boot loader and rewriting GRUB.

This might be long (sorry I am new to Linux) but it worked for me just fine. I now have Win7 and Ubuntu 14.04 in dual boot config.
