Since I got a blank screen after installation, I tried to reinstall the server OS 12.04 using the CD.

This time after the country and login information are given, it asks me to specify some scsi settings. I don't recall doing any such thing. What can this be? Without doing this step, it says that there's no root. I've got 2 HDDs and I initially specified them as RAID during the last installation.

I think I've messed up the settings and I just want to reinstall the whole thing afresh. Any ideas please...

This is not an answer, but I am having the same problem as the OP. > >3.In the terminal, type: sudo dd if=/dev/zero of=/dev/sda bs=1M count=8 && sync >4.And then type: sudo dd if=/dev/zero of=/dev/sda bs=1M count=8 && sync It appears steps 3 and 4 are the same, is this a mistake? – user88960 Sep 11 '12 at 17:27

Warning: this will completely wipe your hard drives

  1. Boot from the Ubuntu Installer/Live CD, and choose "Try Ubuntu..."
  2. At the Live Desktop, press Ctrl-Alt-T to open a terminal.
  3. In the terminal, type: sudo dd if=/dev/zero of=/dev/sda bs=1M count=8 && sync
  4. And then type: sudo dd if=/dev/zero of=/dev/sda bs=1M count=8 && sync
  5. Shut-down the LiveCD.
  6. Insert the Server CD and start installation.

Note: *If your computer is very old and uses IDE cables for the hard drives (wide connector), you may have to use hda instead of sda

thank you for your inputs but I don't have a try option. It's the Ubuntu server without a desktop. – itsols Sep 10 '12 at 5:08
