How many partitions can DOS and Windows recognize?

Updated: 08/31/2020 by Computer Hope

A computer running Microsoft DOS and Windows can support up to 24 drive letters or partitions, or "A" to "Z" with "A" and "B" being assigned to your floppy disk drives.

Note

When creating partitions using Microsoft fdisk, the computer is only capable of having one primary partition per hard drive. All other partitions will be extended partitions.
