Question: Recently I put a Windows 7 hard disk on my XP box, but it has been displayed as "GPT Protective Partition" in Disk Management. I do not know why and how to solve this problem. Is there any good solutions?
Answer: of course, there are some approaches to this tiresome question. And some excellent partition software can play a significant role in getting rid of this troublesome issue.
Reason of "GPT Protective Partition"
As known to many Windows users, GPT hard drive can only support some versions of the Windows NT OS, such as, Windows 2003 64bit, Vista, 2008, Win7 and Win8. On the contrary, the Windows XP does not work With GPT, so that it can not read or access GPT partitions as well. In this case, one solution is to convert GPT to MBR.
Comparison between GPT and MBR
- The MBR hard disk can only support disks that are less than 2TB, while there is no limitation on GPT.
- The MBR can support most versions of the Windows OS, while the GPT just support some Windows NT OSs as mentioned before.
