Attache a -not allocated- space to partition C

Hello Daniel!

Thank you for finding time to open the thread regarding this question, I will be glad to address it!

In order to add this unallocated space to the C: drive, I would advise you to do the following: 

1. First of all, before performing any operation with the hard drive, please go to Start -> Run -> cmd, issue there the following command:
   chkdshk /f /r
   and reboot the machine.
   Upon booting Windows will check the drives for consistency, and make sure that all possible issues on the drive are fixed. Bad blocks and errors in the file system may cause hard drive boot or data access failure, and it's important to make sure that the drive is safe.
2. Download the most recent updated bootable media from your account, burn it onto the CD, boot your machine from it, and proceed with the resizing:
3. (Please follow the screenshot instructions, just use C: drive instead of A:, and E: instead of B:, as on the screenshot)
   Right click on your E: drive, choose Resize volume, and increase the volume to capture the unallocated space. Do not commit changes
   
4. After that decrease the E: drive to the original one, leaving the unallocated space between your C: and E: drive. Do not commit changes
   
5. Click OK
6. Right click on your C: drive -> Resize volume -> increase the volume size to capture the unallocated space
   
7. Commit changes

This should work.
