Dual-Boot Ubuntu 14.04 and Windows 7 on FakeRAID Installation error - question marks "????..."
Here's the issue:
dmraid
was replaced by mdadm
for handling FakeRAID in Ubuntu 14.04.
Here's the solution:
- Boot the installation disk and choose Try Ubuntu.
- Connect to the internet. (crucial step, you need to install from the repository.)
-
Open terminal and type the following:
sudo dmraid -a n sudo apt-get install mdadm
This will disable
dmraid
and installmdadm
. You will be prompted with postfix configuration, chose No Configuration.
-
To automatically recognize your FakeRAID, run:
sudo mdadm --assemble --scan
Run the installer.
- Choose Install Ubuntu.
- Choose to partition manually and create an EXT4 partition mounted as
\
and a SWAP partition. - When choosing where to write the Boot-Loader, Choose the volume mounted as "/".
- Proceed with the installation. Note: The installer will fail to write GRUB.
- Reboot the installation disk and choose Try Ubuntu again.
- Connect to the internet.
- Install Boot Repair and run it. It will guide you on fixing the boot loader and rewriting GRUB.
This might be long, but it worked for me. I now have Windows 7 and Ubuntu 14.04 in dual boot configuration.

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_Volume0 \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 "linear".
I choose
\dev\mapper\isw_gchdghhd_Volume0
as boot device.When immediately after the installation begins, an error with question marks pops up, and the installation stops.

Timothy Smith about 4 yearsThis answer solved my problem after hours of effort. I was trying to install Ubuntu 18.04 alongside Windows 7 on an Intel Rapid Storage Technology Fake RAID. When the installer failed to write GRUB, it stopped responding and I had to kill it, but at that point it had done enough that I could continue the remaining steps. It works fine now.
