    GRUB loading. error:uknown filesystem


    Hello

    This is my first post so I will try to explain the problem as well as possible.

    I bought a Windows 7 netbook and created two new partitions. A 2 gig swap partition and 30 gigs free space,

    I then downloaded Ubuntu 10 netbook edition and installed it to the 30 gig free space. At this point everything worked, when I booted my netbook I was welcomed to a GRUB selection screen and was able to go into both Windows 7 and Ubuntu.

    Here is where the problem started. I used the Windows 7 partitioning software and set the 30 gig Ubuntu partition back to free space. I then downloaded Mandriva One and used Win2Flash to create a bootable Mandruva USB. Using the USB i installed Mandriva One on the 30 gig partition.

    Now when I boot I get the message: "GRUB loading. error:uknown filesystem", and a command line pointer: "recovery>".

    I can not boot into either Windows 7 or Mandriva, but still have the bootable Mandriva USB.

    Running the command fdisk -l gives this output:

    Partition table entries are not in disk order
    To the best of my knowledge:
    /dev/sda1 = system partition, came with Windows 7.
    /dev/sda2 = recovery part for win 7.
    /dev/sda3 = win 7 installation
    /dev/sda4 = not sure about this one
    /dev/sda5 = swap
    /dev/sda6 = Mandriva installationi

    Help please?
