This article describes the steps to convert a basic disk to a dynamic disk in Windows 7.
NOTE: When you convert a disk to dynamic storage, Windows 7 can read it, but the other operating systems may not. This process is not reversible. To change the format of a disk and return to basics, you should create partitions on the drive again. You should also take into account that some portable computers do not support dynamic disks. It is highly recommended that you perform a full backup of the hard disk before making any changes to your partitions, see the article Backing up data on a Windows-based computer for help with procedures.
