When you are unable to make changes to partitions using Disk Management below are partitioning programs you can use.

EASEUS Partition Master (free):

Includes Partition Manager, Disk & Partition Copy Wizard and Partition Recovery Wizard for Windows XP/Vista/Windows 7 (32 bit and 64 bit). It allows users to Resize/Move Partition, Extend System Drive, Copy Disk & Partition, Merge Partition, Split Partition, Redistribute Free Space, Convert Dynamic Disk, Partition Recovery and more. Be careful, re-sizing partitions is usually safe but errors can happen, and always backup anything important before modifying partitions on your hard drive.

Paragon Partition Manager (free):

A good program for making general changes to hard drive partitions while Windows is running. Create, delete, format, and resize partitions with this program. It can also defragment, check file system integrity, and more. Be careful, re-sizing partitions is usually safe but errors can happen, and always backup anything important before modifying partitions on your hard drive.

Gparted Boot Disk(free):

If you can't make the changes you want with Windows running using a Gparted boot disk to change the partitions is a good solution. If you will be changing the main Windows partition, or a partition with important info, backup anything important - it's not common, but things can go wrong. Altering the partitions can be risky, be careful and know what you are doing - there is no Windows safety option when using this - if you tell it to format the Windows partition it will do so and delete the entire Windows installation. Depending on what you are doing it can take from a few minutes to a couple hours. Download the ISO and burn it to a CD.

  3. Choose your language and click Next.
  4. Click Repair Your Computer and then select the operating system you want to repair.

bootrec /rebuildBCD

Note: there is a space before the /

    I actually tried this before and it would not work then.  I was hoping when I watched your vid it would be something I have not tried.  The only step that is different that I performed and hopefully will not be the thing I did that ruined it for me.  I made the disk a Dynamic.  Once I did this, I can no longer make it a simple.  I was told to do this by my I.T. guy because it would allow me to expand the partition.  I had two SSD's to do this to.  One worked fine.  But when I tried to expand the partition containing the OS on the other ssd, it would not allow it.  It would go through the wizard and at the end would give me a warning about expanding the boot partition and gave me the option to continue.  when I did, it have me another message saying it can't be done to a boot partition.

    So my next method was PowerShell.  I could not get it to work because every command in my research to do this is not recognized as a Cmndt..or whatever it is called.  I even got the instructions from Microsoft website and it was not recognizing the commands..things like Get-Partition is not a working command!?

    And yes, I right clicked on PowerShell and selected Admin for launch.

    Note:  When watching your vid and comparing it to what I am seeing on mine...the order of the partitions and the unused space it in the same locations/order.  However, the partition boxes have a green line in them and mine has a blue.  Both of our unused spaces has a black line and it slightly grayed out.

    I have made this video that will show the steps on how to easily extend you primary partition typically the ‘C’ drive on a Windows 7 PC.

    Its straight forward and you do not need to install any third party software, just use Windows provided disk management tools.

    One caveat though, you should be able to have content on the drive next to your C drive that you can back up and move back.
