How to create Partitions in Windows 7 and windows 8?

  Guide to manage partitions:

      It easy to create partitions in Microsoft Windows 7 and windows 8. The Windows 7 Disk Management tool provides a simple interface for managing partitions and volumes. Same method should work for creating partitions in Windows 8. There are two stages in creating a partition:

• Shrink volume to create unallocated space for new partition:

(If you already have unallocated space then skip this step).Here’s an easy way to shrink a volume to free up space so you can create a new partition on your disk. To shrink a basic volume, simple volume, or a spanned volume:

1. Open the Disk Management console by typing diskmgmt.msc at an elevated command prompt.
   
   
2. In Disk Management, right-click the volume that you want to shrink, and then click Shrink Volume.
   
   
3. In the field provided in the Shrink dialog box, enter the amount of space by which to shrink the disk.
   
   
   
   The Shrink dialog box provides the following information:
   Total Size Before Shrink In MB Lists the total capacity of the volume in MB. This is the formatted size of the volume.
   Size Of Available Shrink Space In MB Lists the maximum amount by which you can shrink the volume. This doesn’t represent the total amount of free space on the volume; rather, it represents the amount of space that can be removed, not including any data reserved for the master file table, volume snapshots, page files, and temporary files.
   Enter The Amount of Space To Shrink In MB Lists the total amount of space that will be removed from the volume. The initial value defaults to the maximum amount of space that can be removed from the volume. For optimal drive performance, you should ensure that the volume has at least 10 percent of free space after the shrink operation.
   Total Size After Shrink In MB Lists what the total capacity of the volume in MB will be after you shrink the volume. This is the new formatted size of the volume.
4. Click Shrink.

Once you have unallocated space, you can use that space to create a new partition. 

• Creating Partitions:

1. In Disk Management’s Graphical view, right-click an unallocated or free area, and then click New Simple Volume. This starts the New Simple Volume Wizard.
   
   
2. Read the Welcome page and then click Next.
3. The Specify Volume Size page specifies the minimum and maximum size for the volume in megabytes and lets you size the volume within these limits. Size the partition in megabytes using the Simple Volume Size field and then click Next.
   
   
4. On the Assign Drive Letter Or Path page, specify whether you want to assign a drive letter or path and then click Next. The available options are as follows:
   
   
   
   Assign The Following Drive Letter Select an available drive letter in the selection list provided. By default, Windows 7 selects the lowest available drive letter and excludes reserved drive letters as well as those assigned to local disks or network drives.
   Mount In The Following Empty NTFS Folder Choose this option to mount the partition in an empty NTFS folder. You must then type the path to an existing folder or click Browse to search for or create a folder to use.
   Do Not Assign A Drive Letter Or Drive Path Choose this option if you want to create the partition without assigning a drive letter or path. Later, if you want the partition to be available for storage, you can assign a drive letter or path at that time.
5. Use the Format Partition page to determine whether and how the volume should be formatted. If you want to format the volume, choose Format This Volume With The Following Settings, and then configure the following options:
   
   
   
   File System Sets the file system type as FAT, FAT32, or NTFS. NTFS is selected by default in most cases. If you create a file system as FAT or FAT32, you can later convert it to NTFS by using the Convert utility. You can’t, however, convert NTFS partitions to FAT or FAT32.
   Allocation Unit Size Sets the cluster size for the file system. This is the basic unit in which disk space is allocated. The default allocation unit size is based on the size of the volume and, by default, is set dynamically prior to formatting. To override this feature, you can set the allocation unit size to a specific value. If you use many small files, you might want to use a smaller cluster size, such as 512 or 1,024 bytes. With these settings, small files use less disk space.
   Volume Label Sets a text label for the partition. This label is the partition’s volume name and by default is set to New Volume. You can change the volume label at any time by right-clicking the volume in Windows Explorer, choosing Properties, and typing a new value in the Label field provided on the General tab.
   Perform A Quick Format Tells Windows 7 to format without checking the partition for errors. With large partitions, this option can save you a few minutes. However, it’s usually better to check for errors, which enables Disk Management to mark bad sectors on the disk and lock them out.
   Enable File And Folder Compression Turns on compression for the disk. Built-in compression is available only for NTFS. Under NTFS, compression is transparent to users and compressed files can be accessed just like regular files. If you select this option, files and directories on this drive are compressed automatically.
6. Click Next, confirm your options, and then click Finish.
   
   

The Windows 7 Disk Management tool will now show the space configured as a new partition.
