If you cannot start your computer, you can run the Recovery Console from the Microsoft Windows XP startup disks or the Windows XP CD-ROM. This article describes how to perform this task.
After Windows XP is installed on your computer, to start the computer and use the Recovery Console you require the Windows XP startup-disks or the Windows XP CD-ROM.
To run the Recovery Console from the Windows XP startup disks or the Windows XP CD-ROM, follow these steps.
1. Insert the Windows XP startup disk into the floppy disk drive, or insert the Windows XP CD-ROM into the CD-ROM drive, and then restart the computer. Click to select any options that are required to start the computer from the CD-ROM drive if you are prompted.
2. When the “Welcome to Setup” screen appears, press R to start the Recovery Console.
3. If you have a dual-boot or multiple-boot computer, select the installation that you must access from the Recovery Console.
4. When you are prompted, type the Administrator password. If the administrator password is blank, just press Enter.
5. At the command prompt, type the appropriate commands to diagnose and repair your Windows XP installation.
For a list of commands that are available in Recovery Console, type recovery console commands or help at the command prompt, and then press Enter.
For information about a specific command, type help commandname at the command prompt, and then press ENTER.
6. To exit the Recovery Console and restart the computer, type exit at the command prompt, and then press ENTER.
How to use the Recovery Console command prompt
When you use the Recovery Console, you are working at a special command prompt instead of the ordinary Windows command prompt. The Recovery Console has its own command interpreter. To enter this command interpreter, you are prompted by Recovery Console to type the local Administrator password.
When the Recovery Console starts, you can press F6 to install a third-party SCSI or RAID driver, in case you need such a driver to access the hard disk. This prompt works the same as it does during installation of the operating system.
The Recovery Console takes several seconds to start. When the Recovery Console menu appears, a numbered list of the Windows installations of the computer appears. (Generally, only C:\Windows exists). Press a number before you press ENTER, even when only one entry appears. If you press ENTER without selecting a number, the computer restarts and begins the process again.
When you see the prompt for %SystemRoot% (generally C:\Windows), you can start using the available commands for the Recovery Console.
The following list describes the available commands for the Recovery Console.
Attrib changes attributes on one file or subdirectory.
Batch executes commands that you specify in the text file, Input file. Output file holds the output of the commands. If you omit the output file parameter, output appears on the screen.
Bootcfg modifies the boot.ini file for boot configuration and recovery.
CD (Chdir) operates only in the system directories of the current Windows installation, removable media, the root directory of any hard disk partition, or the local installation sources.
Chkdsk The /p switch runs Chkdsk even if the drive is not flagged as dirty. The /r switch locates bad sectors and recovers readable information. This switch implies /p. Chkdsk requires Autochk. Chkdsk automatically looks Autochk.exe in the startup folder. If Chkdsk cannot find the file in the startup folder, it looks for the Windows 2000 Setup CD-ROM automatically decompresses the file.
Cls clears the screen.
Copy copies one file to a target location. By default, the target cannot be removable media, and you cannot use wildcard characters. Copying a compressed file from the Windows 2000 Setup CD-ROM automatically decompresses the file.
Del (Delete) deletes one file. Operates within the system directories of the current Windows installation, removable media, the root directory of any hard disk partition, or the local installation sources. By default, you cannot use wildcard characters.
Dir displays a list of all files, including hidden and system files.
Disable disables a Windows system service or driver. The variable service_or_driver is the name of the service or driver that you want to disable. When you use this command to disable a service, the command displays the service’s original startup type before it changes the type to SERVICE_DISABLED. Note the original startup type so that you can use the enable command to restart the service.
Diskpart manages partitions on hard disk volumes. The /add option creates a new partition. The /delete option deletes an existing partition. The variable device is the device name for a new partition (such as \device\hard disk 0). The variable drive is the drive letter for a partition that you are deleting (for example, D). Partition is the partition-based name for a partition that you are deleting, (for example: \device\harddisk0\partition1) and can be used instead of the drive variable. The variable size is the size, in megabytes, of a new partition.
Enable enables a Windows system service or driver. The variable service_or_driver is the name of the serviceor driver that you want to enable, and start_ type is the startup type for an enabled service. The startup type uses one of the following formats:
Exit quits the Recovery Console, and then restarts the computer
Expand expands a compressed file. The variable source is the file that you want to expand. By default, you cannot use wildcard characters. The variable destination is the directory for the new file. By default, the destination cannot be removable media and cannot be read only. You can use the attrib command to remove the read only attribute from the destination directory. The option /f:filespec is required if the source contains more than one file. This option permits wildcard characters. The /y switch disables the overwrite confirmation prompt. The /d switch specifies that the files will not be expanded and displays a directory of the files in the source.
Fixboot writes a new startup sector on the system partition.
Fixmbr repairs the startup partition’s master boot code. The variable device is an optional name that specifies the device that requires a new Master Boot Record. Omit this variable when the target is the startup device.
Format formats a disk. The /q switch performs a quick format. The /fs switch specifies the file system.
Help If you do not use the command variable to specify a command, help lists all the commands that the Recovery Console supports.
Listsvc displays all available services and drivers on the computer.
Logon displays detected installations of Windows and requests the local administrator password for those installations. Use this command to move to another installation or subdirectory.
Map displays currently active device mappings. Include the arc option to specify the use of Advanced RISC Computing (ARC) paths (the format or boot.ini) instead of Windows device paths.
MD (Mkdir) operates only within the system directories of the current Windows installation, removable media, the root directory of any hard disk partition, or the local installation sources.
More/Type displays the specified text file on screen.
Rd (Rmdir) operates only within the system directories of the current Windows installation, removable media, the root directory of any hard disk partition, or the local installation sources.
Ren(Rename) operates only within the system directories of the current Windows installation, removable media, the root directory of any hard disk partition, or the local installation sources. You cannot specify a new drive or path as the target.
Set displays and sets the Recovery Console environment variables.
Systemroot sets the current directory to %SystemRoot%
Recovery Console Rules
Several environment rules are in affect while you are working in the Recovery Console. Type set to see the current environment. By default, these are the rules:
Ø AllowAllPaths=FALSE prevents access to directories and subdirectories outside the system installation that you selected when you entered the Recovery Console.
Ø AllowRemovableMedia=FALSE prevents access to removable media as a target for copied files.
Ø AllowWildCards=FALSE prevents wildcard support for commands such as copy and del
Ø NoCopyPrompt=FALSE means that you are prompted by the Recovery Console for confirmation when overwriting an existing file.
