What is the main difference between MBR and GPT?
The main difference between MBR and GPT is the way they partition the hard drive. MBR (Master Boot Record) is an older partitioning scheme that uses a 32-bit integer to store the starting and ending sectors of each partition, limiting the total number of partitions to four primary partitions or three primary partitions and one extended partition. GPT (GUID Partition Table), on the other hand, uses a 64-bit integer, allowing for a virtually unlimited number of partitions.
In addition to the number of partitions, GPT also provides more robust features such as partition GUIDs, which make it easier to identify and manage partitions. GPT also allows for partition sizes larger than 2TB, making it a more modern and scalable option for modern hard drives and SSDs.
