MBR and GPT are two different partitioning schemes used to organize data on a hard drive. Here are the key differences between MBR and GPT:

MBR (Master Boot Record):

• Older partitioning standard that uses a table to map out the partitions on a hard disk.
• Can accommodate up to four primary partitions or three primary partitions plus one extended partition.
• Supports BIOS systems and is the most common format.
• Has a maximum capacity of 2 terabytes.
• Stores the partitioning and boot data in one place, which can be a disadvantage if this data is overwritten or corrupted.

GPT (GUID Partition Table):

• Newer partitioning standard that uses a table to map out the partitions on a hard disk.
• Can accommodate an infinite number of partitions.
• Supports UEFI systems.
• Has no size limitations and can support drives larger than 2 terabytes.
• Stores the data about how all the partitions are organized and how to boot the OS throughout the drive, making it more robust and providing better data protection and recovery options compared to MBR.

In summary, MBR is an older partitioning standard that is compatible with BIOS systems and has a maximum capacity of 2 terabytes, while GPT is a newer partitioning standard that is compatible with UEFI systems and has no size limitations. GPT is more robust and provides better data protection and recovery options compared to MBR.
