Partitioning Hard Drive: The example below describes sharing a hard disk of 500 GB. size, which is preinstalled on a Windows system.

- Create and format hard disk (Winchester) partitions: New or old computer, it is essential that hard disk to be divided (partitioned) into several logical drives (at least two), with free Disk Management Service included in Windows. Can divide existing partition or create a new partition or volume. Microsoft - Formatting disks and drives...

I did it so:

  • 1.) I have a single, unpartitioned, 500 GB hard-disk with Windows 7 x64 preinstalled

  • 2.) This disk has planned to split in two, to have an establishment: C:\ of 100 GB for system, and another drive D:\ for mixed content.

  • 3.) For this I used Disk Management program of Windows.

This can be created on safe mode, because no change the files system (no delete or overwrite).

  • 1.) The downside: Shrink only to hidden system files.

For example: Paging file is hidden file system, installed away from all other files to edge of the hard disk. Therefore, instead of the planned 100GB, I managed to shrink only 220 GB of 500 GB.


Remained a partition 220 GB for drive C:\, and one 280 GB for drive D:\ now disk blank.

In final solution, this method is good.

  • 1.) Windows system can't "see" unformatted unit, and it does not automatically appear in My Computer. I formatted in NTFS file system.

Just a note: Of partition obtained, D:\ 280 GB size, I "cut" (with a new shrink) 80 GB, which is used to test and another system such as Linux or similar, or storing images, photos, video etc.

In the example above (220 GB reduction), can be reached ideal 100 GB, but can only be achieved with a resettlement the paging file. The new installation process will automatically detect this file, and install again in center of hard disk.

Do the following:

  • 1.) - Click on the Start menu button, below the left side of the tray.

  • 2.) - Select All Programs.

  • 3.) - Select Security and Support. (this file appears with your computer or laptop brand names, for example Vaio - Security and Support or Packard Bell - Security and Support, etc.).

  • 4.) - Select Recovery Management (shown as brand names described above).

  • 5.) - In the window that appears, select: Restore to factory settings (or similar), for partitioning Hard disk.

  • 6.) - Will ask if you want to continue?. Click Yes button. Reboot computer and start the installation, then you can decrease drive C:\, with the method described above.

Warning! Save important information on a USB flash drive or DVD disk, because each installation removes all data on the drive, from the device, if you have only one unit. If you have another drive (eg D:\) copy the data stored there.
