Title: Comprehensive Guide to Disk Partitioning and Configuration for Windows 10 Installation using DiskPart
Abstract
The installation of Windows 10 requires a properly configured hard drive partition structure. While the Windows Setup graphical user interface (GUI) provides basic partition management tools, it often lacks the granularity required to resolve complex storage issues, such as stubborn partitions or corrupted Master Boot Records (MBR). This paper provides a technical examination of DiskPart, a command-line disk management utility included in Windows PE (Preinstallation Environment). It details the methodology for sanitizing storage drives, converting partition styles between MBR and GPT, and creating the necessary system partitions for a successful Windows 10 deployment.
