3 Answers. The limitation is 4 Primary partitions and comes from the structure of the Master Boot Record(MBR). However, you could have 3 primary partitions and 1 extended partition which can have any number of logical partitions within it. EFI supports GUID partition tables, which do not have this limitation.
Why are there only 4 primary partitions?
The design decision way back then was to only allow four partitions, but allow one of them to be an ‘extended’ partition that was a pointer to another spot on the disk that could contain a lot more ‘logical’ partitions. (This is the same reason why MBR formatted disks have trouble with 2TB+ disks.
How many primary partitions can be created in Linux?
