Therefore, if the disk size is up to 2TB or if you want to create more than 4 primary partitions, you may need to convert MBR to GPT disk.
GPT, namely GUID Partition Table, provides a more flexible principle for partitioning a hard disk. GPT has been developed only a short time, but its advantages are visible. Therefore, more and more people are interested in learning more about GPT disk and want to convert MBR to GPT disk.
Sometimes, you may want to convert MBR to GPT. How much do you know about MBR and GPT disk? Well, when building a new hard disk in computer, you often need to format the new hard disk in order to make it available. When formatting the hard disk, Windows system will give you two options: MBR and GPT. Simply say, both MBR and GPT are two different modes of formatting your hard disk and both of them have their own advantages and disadvantages.
Advantages of GPT Disk
Although GPT disk has those advantages, it also has its limitations that GPT cannot work on all Windows operating system. For example, Windows XP and Windows 2000 are unable to support GPT disk. If you don’t convert GPT to MBP disk on Windows which cannot support GPT disk, you will be unable to access data. Therefore, you can boot from a GPT disk only if your computer has an operating system Like Windows 7 or Windows Vista that supports GPT disk and the motherboard has an EFI BIOS.
