    Smile cannot unmount windows (hp backup) partition in Wubi ubuntu installation

    hi guys,in my dual boot laptop(Compaq with windows and Ubuntu 10.04), I have two windows partitions
    one is hp backup partition and other is the file system in windows. I tried to share windows files in Ubuntu with ntfs-config, but now the problem is I can only see the hp backup partition on my desktop. When I try to unmount it I could not. My question is how can I unmount the hp backup partition permanently and mount the other partition for file sharing in Ubuntu, I almost forgot..I have also uninstalled ntfs configuration tool.thanks/

    Re: cannot unmount windows (hp backup) partition

    Um ... this looks like a Wubi install to me - You installed Ubuntu within Windows? I don't know very much about Wubi but I think the host Windows partitions are already mounted for you at:
    /host
    /media
    You don't need to have anything else mounted in fstab.

    If I were you I would change the title of your post to include the word Wubi so that someone who has experience with that can respond.

    If your trying to use this method as a longterm use your going about in a a manner that is balancing on the Windows program always working, not good odds. The two OS can have stuff transferred, but a real dual boot would be a better option.
