→Initializing a New Disk
Click on OK to initialize the disk. Once completed the disk will be listed with the chosen partition style with the space marked as ''Unallocated'' in the graphical view. The next step is to create partitions on the disks or use them as dynamic disks. These topics are covered in subsequent chapters.
== Converting Disks between MBR and GPT partition Styles ==
Once a disk have been initialized as GPT or MBR it is quite possible that one day the disk partition style will need to changed. There is good news and bad news regarding converting partition style. The good news is that this can be achieved either using the Disk Management tool or from the command line using ''diskpart''. the bad news is that conversions can only be performed on empty disks. This means that any pre-existing volumes on the disk must be backed up and deleted before performing the conversion.
To perform a conversion from the Disk Management, right click on the icon for the empty drive in the graphical view. If the disk is currently using MBR then the menu will provide the option to ''Convert to GPT Disk''. Alternatively, if the disk is currently using the GPT partition style the ''Convert Disk to MBR'' menu option will be presented. In either case, selecting the conversion option will immediately and silently change the partition style.
To perform the same task suing diskpart, begin listing the available disks:
<pre>
</pre>
Select the desired disk (in this disk 1):
<pre>
</pre>
Finally, convert the disk using the ???? command:
<pre>
</pre>
