How to format a system partition


  • Currently Win 8.1 Pro 64 Bit is the primary OS installed on the C drive.

    Win 7 is installed on the D drive. The D drive also includes a 55MB OEM Partition and a 10GB unallocated space before the drive D partition. Drive D is the "system" partition

    This system was configured for dual boot but now I no longer need to boot to Win 7.

    I dropped Win 7 from boot up using MSConfig.

    How can I format the Win 7 partition on the D drive to recover the space plus merge the unallocated space

    When I run Diskmgmt the format and delete volume options are grayed out for drive D

    I would use a 3rd party tool like easus partition master 9.0 (free to try), it is pretty much bullet proof

  • The Win 7 partition on the D drive is the only "system" partition.

    If I reformat this partition and/or delete it will this prevent the PC from booting?

    Yes.  DO you have a dvd to re-install it?  Unsure if you merely want to expand the system partition to include the una;llocated space & OEM space.

    What exactly do you want to do?

  • The C drive is an SSD, the D drive is the original HD.

    Ideally I would want the C drive partition to be the system partition and the Dr drive just data without Win 7 and the Programs.

    I do have the Win 8 DVD but I was hoping for a less drastic process than reformatting both drives and starting over.

    Sounds like the answer is just to expand the D drive partition using a 3rd party utility.

    Thanks for your help.
