The Recovery Console is a special
boot up method that can be used to help fix problems that are preventing your
Windows installation from properly booting up into Windows. This method allows
you to access the files, format drives, disable and enable services, and other
tasks from a console prompt while the operating system is not loaded. It is
suggested that the Recovery Console is to only be used only after Safe mode and
the other standard startup options do not work. I feel that the Recovery
Console is also useful in other situations such as removing malware files that
start in both Safe mode and Standard Mode and thus not allowing you to delete
the infection.
This tutorial will guide you through
the installation of the Recovery Console and how to use it. For those who are
familiar with DOS or the command prompt, you will find the Recovery Console to
be very familiar. For those who are not comfortable with this type of
environment, I suggest you read through this primer in order to get familiar
with this type of interface:
Introduction to the
Windows Command Prompt
I recommend that you install the
Recovery Console directly onto your computer so that if you need it in the
future, it is readily available. The Recovery Console only takes up
approximately 7 megabytes so there is no reason why you should not have it
installed in case you need it.
To install the Recovery Console on
your hard drive, follow these steps:
- Insert the Windows XP CD into your CD-ROM drive.
- Click the Start button.
- Click the Run menu option.
- In the Open: field type X:\i386\winnt32.exe
/cmdcons , where X is the drive letter for your CD
reader, and press the OK button. An image of this step can be found
below:
- After pressing the OK button a setup window will appear
similar to the one below.
Simply
press the Yes button to continue with the installation of the Recovery
Console. The setup program will then attempt to do a Dynamic Update to make
sure you have the latest files as shown below.
Simply allow it to continue and then when it is finished, you will be presented with a screen similar to the one below telling you so.
- Press the OK button and remove the CD from your computer.
Now when you start your computer you
will have an option to start the Recovery Console.
To start the Recovery Console when
it is installed on your hard drive you would do the following:
- Reboot your computer and as Windows starts it will
present you with your startup options as shown in the figure below.
- With the arrows keys on your keyboard select the option
listed as Microsoft Windows Recovery Console and press the
enter key on your keyboard.
- The Recovery Console will start and ask you which
Windows installation you would like to log on to. If you have multiple
Windows installations, it will list each one, and you would enter the
number associated with the installation you would like to work on and
press enter. If you have just one Windows installation, type 1
and press enter.
- It will then prompt you for the Administrator's
password. If there is no password, simply press enter. Otherwise
type in the password and then press enter. If you do not know your
password then see this.
- If you entered the correct password you will now be
presented with a C:\Windows> prompt and you can start
using the Recovery Console.
- Proceed to How to use the Recovery Console.
To start the Recovery Console
directly from the Windows XP CD you would do the following:
- Insert the Windows XP cd in your computer.
- Restart your computer so you are booting off of the CD.
- When the Welcome to Setup screen appears,
press the R button on your keyboard to start the Recovery Console.
- The Recovery Console will start and ask you which
Windows installation you would like to log on to. If you have multiple
Windows installations, it will list each one, and you would enter the
number associated with the installation you would like to work on and
press enter. If you have just one Windows installation, type 1
and press enter.
- It will then prompt you for the Administrator's
password. If there is no password, simply press enter. Otherwise
type in the password and then press enter. If you do not know your
password then see this.
- If you entered the correct password you will now be
presented with a C:\Windows> prompt and you can start
using the Recovery Console.
- Proceed to How to use the Recovery Console.
When the Recovery Console starts it
will ask for your Administrator password before continuing. In many cases when
you have XP pre installed on your computer the Recovery Console will not recognize
your Administrator's password. In these situations it is possible to edit a
registry setting so that the Recovery Console does not ask for a password. This
setting works on both Windows XP Home and Pro editions.
To change this setting do the
following:
- Click on the Start button.
- Click on the Run option
- Type regedit.exe in the open field and press the
OK button.
- Navigate to the HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\WindowsNT\CurrentVersion\Setup\RecoveryConsole
- Change the value of SecurityLevel value to 1
- Close regedit
- Reboot your computer.
Now the Recovery Console will no
longer ask for a password.
Though the Recovery Console looks
similar to a standard command prompt it is not the same. Certain commands work,
while others do not, and there are new commands available to you. There is no
graphical interface, and all commands must be entered by typing them into the
console prompt with your keyboard and pressing enter. This may be confusing for
those who are not familiar with this type of interface, but after doing a few
commands it does becomes easier.
The following is a list of the
available commands that you can use in the Recovery Console. When using the
recovery console you can type help followed by the command to see a more
detailed explanation. For example: help attrib.
Command
|
Description
|
|
|
Attrib
|
Changes attributes on a file or
directory.
|
Batch
|
Executes commands that you specify
in the text file, Inputfile. Outputfile holds the output of the commands. If
you omit the Outputfile parameter, output appears on the screen.
|
Bootcfg
|
Allows you to modify the Boot.ini
file for boot configuration and recovery.
|
CD
|
(Chdir) Change directory. 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
|
Checks a disk for drive problems
or errors. 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
for 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. If Chkdsk cannot
find the installation CD-ROM, Chkdsk prompts the user for the location of
Autochk.exe.
|
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\harddisk0). 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 service or
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:
SERVICE_BOOT_START SERVICE_SYSTEM_START SERVICE_AUTO_START SERVICE_DEMAND_START |
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 for Boot.ini) instead of Windows device
paths.
|
MD
|
(Mkdir) Creates a directory.
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.
|

on screen. More will display a text file one page at a time, while Type
displays the entire text file at once.
|
Rd
|
(Rmdir) Removes a directory.
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) Rename a file or
directory. 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.

Warning: To remove the Recovery Console you need to
modify the Boot.ini file. Modifying this file incorrectly can prevent your
computer from starting properly. Please only attempt this step if you feel
comfortable doing this.
To remove the Recovery Console from
your hard drive follow these steps:
- Double-click on My Computer and then
double-click on the drive you installed the Recovery Console (usually the C:
drive).
- Click on the Tools menu and select Folder
Options.
- Click on the View tab.
- Select Show hidden files and folders and
uncheck Hide protected operating system files.
- Press the OK button.
- Now at the root folder delete the Cmdcons folder
and the Cmldr file.
- At the root folder, right-click the Boot.ini file, and
then click Properties.
- Click to clear the Read-only check box, and then
click the OK button.
- Click on Start, then Run and type Notepad.exe
c:\boot.ini in the Open: field and press the OK button.
- Remove the entry for the Recovery Console. It will look
similar to this:
C:\cmdcons\bootsect.dat="Microsoft Windows Recovery Console" /cmdcons
Make sure you only delete that one entry.
- When you are done, close the notepad and save when it
asks.
- Right click again on the boot.ini file and select Properties.
- Put a checkmark back in the Read-only checkbox and then press the OK button.
The recovery console should now be
removed from your system.
