7.2 System Tools
7.2.4 The ERD and Recovery Console for Win 2K
The systems administrator will encounter computers whose operating systems have become corrupt and cannot function properly or will not even be able to boot up. Usually the problem is that a critical file or program was deleted or changed so that the operating system no longer recognizes it and therefore will no longer work. In Windows 2000 an Emergency Repair Disk (ERD) can be created or the Recovery Console feature can be used. These options help fix these problems by repairing files or copying new files that have been corrupted or damaged so that the hard drive will not have to be reformatted and lose any valuable data.

Emergency Repair Disk
The ERD allows the reinstallation of any service packs that were loaded since the original installation as well as copy files from the CD-ROM of the corrupted files on the hard disk. If the file system becomes corrupt and cannot start, an ERD may provide a solution. If a service pack was applied since the original installation it will need to be reapplied because the files that are copied will be original installation files taken from the CD-ROM.

Creating an Emergency Repair Disk
To create an emergency repair disk, follow these steps:

  1. Run the Backup program (Start > Programs > Accessories > System Tools > Backup)
  2. On the Welcome tab, click the Emergency Repair Disk button
  3. Insert a blank formatted 3.5 floppy disk in Drive A:
  4. Check the box labeled Also Backup The Registry To The Repair Directory
  5. Click OK
  6. Remove the disk and label it "Emergency Repair Disk" with the current date

Using an Emergency Repair Disk
There are two ways the emergency disk can be used. If the system supports a bootable CD-ROM, insert the Windows 2000 CD and boot from the CD. If the system does not support a bootable CD-ROM, insert Setup disk 1 and restart the computer. There will then be a prompt for setup disk 2, then setup disk 3.

  1. Press Enter when asked whether to install Windows 2000
  2. Press R to use the emergency repair diskette
  3. When presented with a Fast or Manual option, press F to select the Fast option
  4. Press Enter to use the Emergency Repair Diskette
  5. Insert the Emergency Repair Diskette and press Enter
  6. Once the files have been repaired, reboot the operating system

Recovery Console
The Windows 2000 Recovery Console is a command-line interface that can be used to perform a variety of troubleshooting and recovery tasks, including starting and stopping services, reading and writing data on a local drive (including drives that are formatted with the NTFS file system), and formatting hard disks. Once the recovery console is started, the commands from the command line can be used to remove, replace, or copy corrupt files.

There is more than one way to start the Recovery Console. The first way is to first insert the Windows 2000 CD-ROM into the CD-ROM drive and wait for the Microsoft Windows 2000 CD dialog box to open. If it opens, close it. If it does not, go to the run command window on the start menu and type "cmd". This will bring up a command prompt window where the administrator can change to the drive letter of the CD-ROM, then change to the I386 folder and run the winnt32 command with the /cmdcons switch. After the Recovery Console is installed, it can be accessed from the Please Select Operating System To Start menu. Another way of starting the recovery console is to start the system with the Windows 2000 setup disks or the CD and enter by selecting the appropriate option when prompted.
