    Dual boot ubuntu 12.10 and windows 8 Dell Inspiron 15 r

    i purchased a new Dell 15R laptop which came with pre installed windows 8 64 bit and ueifi boot. I made a ubuntu 12.10 dvd and loaded it. When i started installing my installer could not recognise any other windows 8 or any other OS installed. When i moved to advanced partition tool, i could see my free space, my windows partitions. But i did not proceed. can anyone help.

    Is this also an Ultrabook which is Intel SRT. The Intel SRT uses RAID and the installer does not have the RAID drivers, so it does not 'see' the partitions.

    Disable the RAID, for me it was using the Intel rapid management thingy and telling it to disable the acceleration or the use of the SSD. If you have a different system, just disable the RAID system then install Ubuntu. Once installed you can then re-enable it.
    You will need to use the dmraid command prior to running the Ubuntu Installer so that it will be able to see the partitions on the drive because otherwise with the raid metadata in place it will see the drive as part of a raid set and ignore its partitions.
