Lesson 2 Objectives


3/23

Windows 7 creates system restore points on a regularschedule and prior to events such as the installation ofapplications and drivers.

A restore pointcontains information about registry settingsand other system information.

Windows 7 generates restore points automatically beforeimplementing significant system changes.

System restore does not alter users files.

When you perform a System Restore following a normal boot or

following a boot that uses the Last Known Good Commnabd

(advanced) option, a restore point is created that enables you to

undo the changes if they do not fix your problem.


4/23

However a System Restore when the computer is in Safe Mode or by usingthe System Recovery Options, cannot be undone. You will have to run

another Restore point.

Windows 7 reserves disk space for system restores and restore points are

saved until this disk space is filled up. At this point, as new restore pointsare created, old ones are deleted.

For a system restore to be effective, you need to ensure that system

protection is enabled and you have at least 300 MB of free space left on

your hard disk.

System protection regularly creates and saves informationabout your computers system files and settings. It also savesprevious versions of files that you have modified. It savesthese files in restore points.Restore Points are created just before significant systemevents, such as the installation of a program or device driverRestore points are also created automatically every sevendays if no other restore points were created in the previousseven days.You can create restore points manually at any time.System protection is automatically on for the drive thatholds the operating system and can be enabled only fordrives that are formatted using the NTFS file system. Itenables you to use system restore and to restore files to

previous versions

The advanced methods available by clicking Advanced RecoveryMethods in the Recovery window under All Control Panel Items inControl Panel can return Windows to a usable state if it is badlydamaged.

There are two Methods that can return Windows to a usablestate. 1) Use a System Image Backup

2) Reinstall Windows either from a recovery image provided by your computer

manufacturer or the original Windows installation files.

Both Methods can result in loss of data. Therefor backup personal files to an external

location such as a USB hard disk.

FYI: Restoring from a system image backup is not the same as performing a system

restore.

Advanced Recovery Methods

A System Image restore rewrites the entire contents of a systemvolume.

You can restore from a System Image backup by booting from theWindows 7 Installation DVD-ROM and loading System Recoverytools or by pressing F8 during the boot process.

Restoring from a System Image backup enables you to quickly get acomputer running after you replace a failed hard disk, or if theoperating system installation has been corrupted.

Typical Restore will take from 30 to 60 seconds per gigabyte.


9/23

On a computer running Windows 7, you can access the AdvancedBoot Options by restarting the computer and holding the F8 keydown while it reboots. You can do this when you boot from theinstallation DVD-ROM or when you boot from hard disk

This gives you a method of accessing repair tools such as system

restore. Safe Mode

Safe Mode with Networking

Enable Boot Logging

Enable Low Resolution Video

Last Known Good Configuration (Advanced)

Directory Services Restore Mode

Debugging Mode

Disable Automatic Restart On System Failure

Disable Drive Signal Enforcement

Start Windows Normally


10/23

If you select Debugging Mode in AdvancedOptions you get 2 options:

1) Use Recovery Tools that can help fix a problem

starting Windows

2) Restore your computer using a system image youcreated earlier.


11/23

If you choose number 1 you are asked to select

an operating system to repair:a) Startup repair- Automatically fixes problems that prevent Windows from starting.

b) System Restore -another method of starting a system restore to a previous restore

point.You can access this menu when you boot from a DVD-ROM, this lets you repairyour system when recent changes to system settings prevent your computer from

booting normally

C) System Image Recovery Enables you to implement a System Image restore. Youwould choose this option if your hard disk failed or needed to be wiped. If systemchanges are causing problems, you would choose the System Restore option.

D) Windows Memory Diagnostic Analyzes the computer memory (RAM) for hardware

problems.

E) Command Prompt Gives access to the file system, volumes, and files through acommand-line interface.


12/23

The Last Known Good Configuration (Advanced) feature in Advanced Boot Options isarecovery option that you use to start your computer with the most recent settingsthat worked.

restores registry information and driver settings that were in effect the last time thecomputer started successfully.

Use the Last Known Good Configuration (Advanced) feature when you cannot startWindows 7 after you make a change to your computer, or when you suspect that a

change that you just made is causing a problem.

Windows 7 Boot Options: Windows 7 implements a boot loader, a boot configuration and storage system called

Boot Configuration Data (BCD), and a boot option editing tool called Bcdedit

Win 7 includes the following Boot loader features:

A) Windows boot manager (Bootmgr.exe) B) Windows OS loader (Winload.exe)

C) Windows Resume loader (Winresume.exe)


13/23

boot options and BCD are stored in the BCD store

enables administrators to assign rights for managing boot options.BCD is available at run time and during all phases of setup,including resuming after hibernation.

You can use the Bcdedit utility to manage BCD remotely andmanage BCD when the system boots from media other than themedia on which the BCD store resides.

This feature is important for debugging and troubleshooting,especially when a BCD store must be restored while runningStartup Repair from DVD-ROM, from USB-based storage media, orremotely.


14/23

You can use the Bcdedit utility to do the following:

Create a BCD storeRebuild BCDAdd entries to a existing BCD storeModify existing entries in a BCD storeDelete entries from a BCD storeExport entries to a BCD store

Import entries from a BCD storeList currently active settingsQuery entries of a particular typeApply a global change to all entriesChange the default time-out value


15/23

First use Last Known Good Configuration orSystem Restore.

If those options are not convient then youboot the computer into Safe Mode or EnableLow Resolution Video and roll back thedriver.

The roll back is to the previous driverinstalled.
