Understanding the Windows 7 Startup Process • Power-on self–test (POST) phase • Initial startup phase • Windows Boot Manager phase – Reads BCD • Windows Boot Loader phase • Kernel loading phase • Logon phase • See table 11-2 for comparison between W7 and XP

Troubleshooting Startup Failures • POST failures • Check BIOS document • Initial startup failures • Incorrect BIOS Settings • Hardware faults • Missing startup files • Data corruption

Troubleshooting Startup Failures • Driver and service failures • The appearance of the progress bar indicates that the kernel has loaded successfully. • Use Last Known Good Configuration or Safe Mode • Use Device Manager • Logon failures • Hold shift key when logging on to prevent programs from loading

Using Recovery Tools • Alternate boot options • Startup and Recovery Dialog box • System Configuration tool • Boot logging • Windows RE

Using Alternate Boot Options • Press F8 after POST to get to the Advanced Boot Options menu: • Last Known Good Configuration • Safe Mode (with network or command prompt) • Press the shift key while logging on and hold it until the icons appear on the desktop to suppress startup applications

Using Startup and Recovery Dialog Box • Provides basic controls that enable you to configure the startup process by modifying the BCD registry file • Start -> Control Panel -> System and Security -> System. Click Advanced System Settings. Click the Advanced tab, as shown in Figure 11-1

Using Windows RE • Allows you to bypass all of the drivers, applications, and services that can be the source of a startup problem • To run: Boot with installation DVD, click Repair Your Computer when prompted

Using the System Recovery Tools • Startup Repair • An automated troubleshooting tool that is capable of diagnosing and repairing a variety of problems that can prevent Windows 7 from starting, including BCD problems and missing startup files • System Restore • System Image Recovery • Enables you to perform a FULL restoration of your computer, using an image you previously created with the Backup and Restore control panel • Windows Memory Diagnostic tool • Command Prompt

Using BranchCache • Enables networks with computers at remote locations to conserve bandwidth by storing frequently accessed files on local drives • Two operational modes • Distributed cached • Each Windows 7 workstation on the branch office network caches data from the content server on its local drive and shares that cached data with other local workstations • Host cached • Server 2008 R2 is required

Using Backup and Restore • Wizard-based • Creates backup of files and folders to a network share, DVD, CD, or other hard disk • System Image Backup • Creates a backup of the entire drive using an image-based utility • Restore files and folders that were previously backed up

Creating a System Image Backup • Creates an image of an entire drive • Saves the information to a virtual hard disk (VHD) on the backup device

Creating a System Repair Disk • Enables you to access system recovery options if you do not have a Windows 7 installation disk or a recovery partition • Bootable disk • Contains recovery tools

Restoring Previous Versions • Volume shadow copies • Duplicates of files that Windows creates as part of a restore point • System Protection feature is required • Restore one of the previous versions by opening its Properties dialog box (or that of its parent) and clicking the Previous Versions tab
