You Can Convert MBR to GPT without Data Loss in Windows 2008
Problem: several months ago I bought a 3TB hard disk for my Windows Server 2008 desktop (only for data storage). I initialized it to MBR and partitioned to 3 drives with 1TB unallocated space left for future use. However, when I planned to create a new drive with the unallocated space, Disk Management refused my operation. Then I googled and found MBR just allows me to use the maximum space of 2TB, and I was suggested to convert it to GPT. How can I convert a MBR disk to GTP without any data loss in Windows Sever 2008? Anyway, I do not have any other external disks to store data on the 3TB disk, and the system disk does not have enough space to hold the content, too. P.S please explain properly and show me detailed steps, because I might not understand what you are saying.
Generally, there are 2 commonly used ways to convert MBR disk to GPT disk. One is to use system built-in disk management tool, and the other is to ask third party server partition manager for help:
To choose the first way, users need to backup all important data on the target disk at first, and then delete all existing partitions. At last, right click the disk and choose "Convert to GPT Disk" item from the shortcut menu.
By employing the second method, Windows Server 2008 users do not need to delete any drive, and the MBR disk can be converted to GPT without any data loss.
Convert MBR to GPT in Windows 2008 via Server Partition Manager
Step 1: download a professional server partitioning program from the internet, and MiniTool Partition Wizard is worth owning. Then, install it in accordance with wizards.

After these 4 steps, we convert MBR disk to GPT in Windows Server 2008 without any data loss since the whole process does not require us to delete any drive or information. Now, download this server partition manager to have a try.
