Many people post a thread like the following on the computer forums:
“I just bought a new hard disk and plugged it in computer, when I go into disk management it says that it needs to initialize the disk before Windows can recognize it and asked if I want to use either MBR (master boot record) or GPT (GUID partition table) as the partition style.”
To select a partition style, you should know something first. What is the volume of your hard disk? If it was smaller than 2TB, you can only initialize to MBR. Because a MBR disk supports up to 2TB per partition. If it was bigger than 2TB, you can initialize to GPT to verify all of the disk space to be usable, but not always can do it. You must make sure your motherboard with UEFI and your operating system support GPT. What is your disk use for? For storage or system? Specific situation you can consult the chart below:
What’s more, MBR disk supports four primary partitions or three primary partitions and one extended partition. By contrast, GPT disk supports theoretically unlimited partitions.
To sum up the above explanation, you can decide to initialize your disk to MBR or GPT.
However, when you want to change your disk style but not want to reinstall OS or delete all existing partitions. Is there a safe and simple way to do this? Yes! AOMEI Partition Assistant is a piece of professional partition management software and is able to convert between MBR and GPTwithout data loss.
