    Setup Windows 7 64bit - Dual Boot


    Hello Forum! :)

    Im new here. I browsed this forum for a bit and decided this is a good place to learn about new things and to get help with problems.

    Well i have a problem.

    I currently have a pc with Windows 7 64bit installed on it.
    Now im tryin to install another Windows 7 64bit on a newly shrinked partition i created - The size is 103gb

    When ever i try to install on the newly created parition i'm gettin this error:

    "Setup was unable to use the existing system partition because it does not contain the required free space"

    Im have lots of free space on the new partition..But i was told that my SYSTEM RESERVED 100mb is whats causing the problem because i only have 1mb free on this partition.

    Im pretty much lost now..Could anyone here provide some advice on how to install
    Another Windows 7 64bit on a newly created partition?

    Many Thanks!

    You simply need to point the installer to the new empty partition. It is now trying to install in the 100 system partition with no success.

    Hello phillizee, welcome to Seven Forums!



    Before we make any specific recommendations will you please post a snip/screen-shot of the entire disk management drive map with a full description as to which drive/partition is which, so we can see what you have going on as there may be a fairly simple way to resolve the situation.

    In the Windows start menu right click computer and click manage, in the left pane of the "Computer Management" window that opens click disk management and post a snip of that.

    And when you point the installer to F: at this dialog box (the snip below) during the install you get "not enough free space" error.



    Maybe you could use Option Four in this tutorial to convert the Extended/Logical to a Primary partition to see if that helps.

    I Downloaded Partition Wizard

    I then set drive F (Win 7 - 64bit Xtreme - The newly created partition were i want to install the other os) to primary.

    Rebooted the pc and started the WIN 7 installation selected option Custom
    Clicked on the Drive F: and i still recieved the same error message."Setup was unable to use the existing system partition because it does not contain the required free space"

    To add: Do u think if i set my original primary drive to logical and use the F drive as primary would give some progress?

    No. Do not convert any OS partition to Logical.

    The problem is likely that something has written to SysReserved, possibly even during factory install, leaving it inadequate space to update the System boot files.

    You can try shrinking the left side of the C drive by 100mb using Partition Wizard bootable CD, then Resize SysReserved into the extra space to add more space to it.

    Back up a Win7 backup image and your files first as resizing can fail, although with Data Protection Mode checked Partition Wizard bootable CD will not fail, only restart to try over until you bail out of it at restart.

    What is Win7 Extreme? How do you plan to activate it?

    I have good news guys. Well after following all of our guidlines and advice i finally got Windows 7 64bit installation working on the other partition.

    I was worried that it would'nt work.


    I followed gregrocker's method by using Partition Wizard to Extend The SYSTEM RESERVED
    space from 100mb to about 200mb.

    Then i started the setup again..and it all went through..Im now able to boot to both partitions
    hassle free - I also used EasyBCD 2.0 to rename one to avoid confusion.

    I would like to thank zigzag3143(Ken J), Bare Foot Kid and gregrocker For their most appreciated inputs in helping me on my journey..

    You Guys Rock!!!
