Windows Boot Process • BOOTMGR is loaded and accesses the Boot Configuration Data Store to display the boot menu or to boot from a partition or volume • WINLoadis the operating system boot loader that loads the rest of the operating system • NTOSKERNL.EXE is the main part of Windows, which is responsible for various system services, processes, and memory management. • Boot-class device drivers implement a number of functions that are utilized in different ways by different hardware platforms based on processor and chipset.

  4. Master Boot Record (MBR) • The first 512-byte boot sector of a partitioned data storage device such as a hard disk • Contains the disk’s primary partition table, and the code to bootstrap an operating system • By default, the master boot record contains the primary partition entries in its partition table

  12. Windows PE • A minimal Win32 operating system with limited services, built on the Windows 7 kernel • To prepare a computer for Windows installation, to copy disk images from a network file server, and to initiate Windows Setup • A component in recovery technology with Windows Recovery Environment (Windows RE)

  13. Windows Recovery Environment • A set of tools to help diagnose and recover from serious errors • WinRE may be installed and/or booted from • Hard disks • Optical media (such as an operating system installation disc) • PXE (e.g., Windows Deployment Services) • See Figure 6-5 on Page 127

  14. BootRec Command • If you prefer to perform a manual repair • Can repair the MBR or the volume boot sector • BootRec.exe can be executed from • Command Prompt in the System Recovery tools • /Fixmbr • /Fixboot • /Scanos
