This tutorial will explain each partition of the default partition layout created when you clean install Windows 10 or Windows 11 on a blank hard disk drive (HDD) or solid-state drives (SSD).
When you clean install Windows 10/11 to a blank unallocated disk with UEFI, the disk is formatted using a GUID partition table (GPT) file system.
The default partition layout for UEFI-based PCs is: an EFI System Partition, an MSR, a Windows partition, and a Recovery Partition.
This layout lets you use Windows BitLocker Drive Encryption or Device Encryption through both Windows and through the Windows Recovery Environment (WinRE).
