    [Solved]Cannot Install-Does not contain the required Free Space


    Friends,
    I'm unable to install Win 8 due to "Setup was unable to use the existing system partition because it does not contain the required Free Space" error, it'd nice if someone can help. The screenshot is from within Windows 7 but when I try to install from outside also by booting from the installation disk, the error is the same. Help much appreciated
    Thank you

    You cannot have 4 primary partitions on the disk (system reserved is also primary), max is 3. You need to convert one of those to logical. What all is installed on them?

    C: = windows 7
    D: = Data
    F: = Free for Windows 8 Installation

    I tried it after making F: as logical, still it is not allowing me to install
    Do I need to make another partition as logical and let F: remain as primary?

    Data drive (D: ) doesn't need to be primary. Just boot from partition wizard boot cd and convert it to logical.

    Hmm...try deleting F: to create unallocated space and see if the installer sees it and installs there. if it doesn't create a new partition by formatting the space.

    30Gb is kinda low. I'd say delete F, forma D, shrink D to more space and make it F again. Then retry.

    Btw, what are your Logical drives? Simple, Basic and NTFS drives?

    I think 30GB is enough and I cannot format D, D has all my data, There are no Logical drives but only one Logical Drive as you can see from the photo above and that is NTFS.

    Move the files to an external drive temporarily.

    If the install says not enough space, increase it and see what happens. I would lol.
