    Hi and welcome to the forums!

    Please press the <super> (Windows logo key) and search for 'Terminal' and open it. Now run this command:

    Code:
    sudo fdisk -l
    Please copy&paste the outputs here so we can have a look.

    The problem most probably is being caused because your HDD is formatted "Dynamic disk" in Windows which is a Microsoft proprietary thing and doesn't work with Linux. However, there are some workarounds which we can offer once we see those outputs.

    It might be that the disk was used in raid before and has meta data remains. Ubuntu can see this and doesn't show the partitions list.

    If you ARE NOT running raid right now, you can boot with the ubuntu cd in live mode and in terminal do:
    sudo dmraid -E -r /dev/sda

    Confirm to remove the meta data. It should work after that.

    Re: I can't make partitions.

    Did you try the dmraid command mentioned in post #3?

    Re: I can't make partitions.

    It is only important if you are running raid in your system. You seem to have only one hdd so it's impossible to run raid.

    If your disk has been used in raid before, the ubuntu installer ignores the disk/partitions until you delete the raid meta data remains. Windows ignores it, but ubuntu doesn't.

    Re: I can't make partitions.

    That doesn't sound good at all. Please be patient and remember that this has nothing to do with the removal of Raid meta-data.

    Probably Grub wasn't installed correctly. Or you somehow didn't install it to its preferred location.

    Whatever it was, now we need you to boot an Ubuntu Live CD/USB and post the output of bootinfoscript as per instructions here:

    http://bootinfoscript.sourceforge.net

    No need to panic, your Windows 7 install will be there hopefully and also the Ubuntu one probably. The only thing you lose is some time, and also some effort.

    After we see the outputs of that script, we can give you easy instructions to re-install the bootloader whether the Windows one or Grub.

    Re: I can't make partitions.

    You shouldn't have deleted the root partition. In situation where you get grub error, don't panic and try to solve it first.

    Deleting the ubuntu partitions will definitely break grub2 even further since it depends on configuration files which are on the root partition. Now they are gone.

    You can try installing ubuntu once more into the same unpartitioned space (if you really deleted it) and if grub still gives you an error run the boot info script as suggested and post the results. It will show more details.

    If nothing of this works, don't worry, there is still an easy way to make win7 boot. Don't worry about win7, lets make your dual boot work.
    Darko.
