Which operating system is loaded during the boot process ! Whether the user is presented with a choice of operating systems during the boot process ! The boot switches that an operating system is loaded with Understanding the contents and the structure of the Boot.ini file enables you to edit the file safely Lesson objectives After completing this lesson, you will be able to: ! Describe the parts of the Boot.ini file and their functions ! Modify a Boot.ini file ! Use the Boot.ini file to change the startup behavior of a computer 22 Module 3: Resolving Boot Process Issues What is the Boot.ini File? *****************************ILLEGAL FOR NON-TRAINER USE****************************** The Boot.ini file is in the root directory of the system partition The Ntldr file uses the information in the Boot.ini file to display the options on the Please Select an Operating System to Start menu Editing the Boot.ini file You can edit the Boot.ini file to: ! Modify the list of operating systems on the Please Select an Operating System to Start menu ! Change a boot switch for an operating system ! Change the boot partition for an operating system Note For more information about how the Boot.ini file affects the boot process, open the Web page on the Student Materials compact disc, click Multimedia, and then click, Examining the Microsoft Windows XP Professional Boot Process Components of the Boot.ini file The following table describes the two sections of the Boot.ini file Section Description [boot loader] The time-out setting and the path to the default operating system [operating systems] The path to each operating system that is installed on the computer Note If you install Windows XP Professional in a multiboot configuration, there is an entry for each operating system Otherwise, there is an entry only for Windows XP Professional Module 3: Resolving Boot Process Issues ARC paths 23 The Boot.ini file uses Advanced RISC Computing (ARC) paths to point to the partitions on which the operating systems reside The following are examples of ARC paths: SCSI(0)disk(1)rdisk(0)partition(1)\Windows=Microsoft Windows XP multi(0)disk(0)rdisk(1)partition(2)\Windows=Microsoft Windows 2000 The following table describes each part of the ARC path Convention Scsi(x) Specifies a SCSI controller on which the SCSI BIOS is not enabled Numbering begins at Multi(x) Specifies any controller other than one that uses the SCSI(x) convention The x represents a number that indicates the load order of the controller Numbering begins at Disk(y) The SCSI ID For Multi, the y value for Disk (y) is always For SCSI, y identifies the disk on which the operating system resides Numbering begins at Rdisk(z) Identifies the disk on which the operating system resides Numbering begins at Partition(a) Boot.ini switches Description Specifies the partition on which the operating system resides Numbering begins at The following table lists the common switches used in the [operating systems] section of the Boot.ini file Switch Function and uses /basevideo Boots the computer by using the standard VGA video driver Use this switch to start Windows XP Professional if a video driver is not functioning, and then change the driver while you are logged on /bootlog Enables boot logging to Ntbtlog.txt in the Systemroot folder For more information about boot logging, see Windows XP Professional Help /debug Loads the Windows kernel debugger when you start Windows XP Professional /fastdetect=[com |comx,y,z] Included with every entry by default, this switch disables serial mouse detection when a port is specified, and disables peripheral detection on all COM ports when a port is not specified /maxmem:n Specifies the amount of RAM that Windows XP Professional uses (The n is the amount of RAM in the computer, in kilobytes or KB.) Use this switch when you suspect that a memory chip is corrupted /noguiboot Boots the computer without displaying the graphical boot status 24 Module 3: Resolving Boot Process Issues (continued) Switch Function and uses /safeboot:parameter Forces the computer to start in Safe Mode by using the specified parameters You can also use these boot options by pressing the F8 key when you are prompted at startup /sos Displays device drivers as they are being loaded Use this switch if you suspect that a startup problem is caused by a corrupted driver Module 3: Resolving Boot Process Issues 25 Ways to Modify the Boot.ini File *****************************ILLEGAL FOR NON-TRAINER USE****************************** Key points ! The safest way to modify the settings in a Boot.ini file is by using Control Panel • You can modify the time-out and default values of the Boot.ini file by using System Properties in Control Panel • You can alter the display names of operating systems that appear on the Please Select an Operating System to Start menu For example, if there are two operating systems on a computer with a dual-boot configuration, you can change the display names of the operating systems to reflect their purposes; for example, “Windows XP Professional Workgroup” and “Windows 2000 Domain.” You can also add or remove switches to the entries under the [operating systems] section of the Boot.ini file For example, you may want to disable the /fastdetect switch ! You can modify the Boot.ini file by using an editor Manually editing Boot.ini requires that you have access to hidden system files, which renders these files vulnerable to corruption ! You can use the System Configuration utility, msconfig.exe, to automate common changes to the Boot.ini when you are troubleshooting Primarily a diagnostic utility for Windows XP Professional, the System Configuration utility also provides control over a large set of the boot options in Boot.ini Advanced options in msconfig.exe include: • /NUMPROC, which sets the maximum number of processes • /DEBUGPORT, which selects a serial port down which to send debug messages • /BAUDRATE, which specifies the bit rate of the serial port specified by /DEBUGPORT 26 Module 3: Resolving Boot Process Issues Practice: Modifying Display Names and Switches *****************************ILLEGAL FOR NON-TRAINER USE****************************** Objectives After completing this practice, you will be able to: ! Modify the display name of an operating system ! Add a boot switch to an operating system Prerequisites Before beginning this practice, you must have a computer running Microsoft Windows XP Professional Scenario You have installed two operating systems on a computer with a dual-boot configuration You will alter the display names of operating systems that appear on the Please Select an Operating System to Start menu to reflect their purposes You are experiencing problems with a computer and you suspect that a driver may not be loading You will use the /sos switch to determine which driver is causing the problem Practice In this practice, you will change the Boot.ini file to: ! Modify the display name of an operating system ! Add a boot switch to an operating system Module 3: Resolving Boot Process Issues 27 ! Modify the display name for an operating system Log on to the local computer as Administrator with a password of P@ssw0rd Click Start, right-click My Computer, and then click Properties On the Advanced tab, under Startup and Recovery, click Settings Under System startup, click Edit To change the display name of an operating system, locate the name of the operating system, which is enclosed in quotation marks, in the [operating systems] section of the Boot.ini file The display name appears as \WINDOWS= “operating system name” Change the name within the quotation marks ! Add a boot switch to an operating system To add the switch, type /sos at the end of the “operating system name” line On the File menu, click Save, close the window, and then click OK twice Reboot the computer ! Remove the /sos switch Log on to the local computer as Administrator with a password of P@ssw0rd Click Start, right click My Computer, and then click Properties On the Advanced tab, under Startup and Recovery, click Settings Under System startup, click Edit Delete /sos from the end of the “operating system name” line On the File menu, click Save, close the window, and then click OK twice Log off the computer 28 Module 3: Resolving Boot Process Issues Lab A: Troubleshooting the Boot Sequence *****************************ILLEGAL FOR NON-TRAINER USE****************************** Objectives After completing this lab, you will be able to: !
