What does rebuild MBR mean?

Does Windows 10 use MBR or GPT?
All versions of Windows 10, 8, 7, and Vista can read GPT drives and use them for data—they just can’t boot from them without UEFI. … If you need compatibility with old systems — for example, the ability to boot Windows off a drive on a computer with a traditional BIOS — you’ll have to stick with MBR for now.
Is NTFS MBR or GPT?
A disk on a computer is usually partitioned in either MBR or GPT (two different partition table). Those partitions are then formatted with a file system, such as FAT, EXT2 and NTFS. Most disks smaller than 2TB are NTFS and MBR. Disks larger than 2TB are NTFS and GPT.
