When you select the disk to convert to GPT, the following are only several steps, and every steps with guidance.The practical steps please visit Convert GPT to MBR or MBR to GPT.

AOMEI Partition Assistant is a good partition converter. Besides converting between MBR and GPT, it can also convert FAT/FAT 32 to NTFS, convert primary to logical partition. Migrate OS to SDD and Windows To Go Creator are two bright functions of it. The former helps you move operating system from old hard disk to new hard disk or SSD quickly without reinstall Windows operating system. The latter helps you make a portable Windows 8 that you no longer need to buy Windows 8 Enterprise Edition.
