I have a new computer with a Seagate ST500DM002 SATA internal hard drive.



I am trying to install Ubuntu 11.10 64-bit on it but the installer does not recognize/detect/see the hard drive. When I reach the Installation type step, the panel which is supposed to show devices and partitions looks empty.



sudo fdisk -l shows only /dev/sda1, the USB drive from which I am running the installation. I have already tried the following two solutions without any success:




  1. sudo apt-get remove dmraid

  2. Switch the SATA mode in the BIOS from IDE to AHCI



I am sure it's not a hardware related problem as I have already successfully installed another operating system on the same computer.



The output of sudo lshw -class storage -class disk follows:

Any idea on what I could do to fix this problem?

As workaround I went in the BIOS and set the SATA Mode to "IDE" and the SATA3 Mode to "AHCI". After doing this the installer did detect the hard drive and installed Ubuntu alongside the other operating system.



I called it a workaround and not a fix because the other operating system won't load with the SATA3 Mode set to AHCI, so every time I need to switch OS I am forced to go in the BIOS and change the SATA3 Mode.



Another problem I had after applying the workaround was that the boot loader didn't show up on the next boot but the other operating started booting without any prompt. I've fixed this other problem by identifying the Ubuntu partition with:



sudo fdisk -l


(which was sda6) and then running:



sudo mount /dev/sda6 /mnt
sudo grub-install --root-directory=/mnt/ /dev/sda
