Tutor: Using The Recovery Console

[b][color=#0000FF]The Recovery Console[/color][/b]

Few of us, like me will attempt to make a fresh installation if something fails and doesn’t bother about entering the recovery console itself. Please keep in mind its one of the most useful tool to recover from the error without any data loss! Whenever u get a errode]r message stating you to fix it in Recovery Console, please don’t neglect it… Go for it… its easy and faster than install the OS again.
The Recovery Console Provides access to your system’s files systems on your HDD (FAT, FAT32 and NTFS). With this level of access, we system admin can access files and dir’s. More importantly, the admin has the capability to start and stop services and therefore repair the system.

[b]Starting the Recovery Console (RC)[/b]

The Recovery Console can be accessed from the Windows XP Professional installation CD-ROM or from your Windows XP Professional Setup floppy disks. It can also be installed to the local hard disk by typing the following command at a command prompt:

[code]D:\I386\WINNT32.EXE /cmdcons[/code]

In this prompt, D: represents the CD-ROM drive where the Windows XP Pro installation CD-ROM is located.

Problems with the boot configuration found in the Boot.ini file can be remedied by using the Recovery Console. The boot configuration can be recovered by using the BOOTCFG command, which contains several parameters to assist you in recovering from a boot configuration failure. The Table below lists and describes the BOOTCFG parameters.

[quote]Warning: When using BOOTCFG /rebuild, always make a backup copy of your Boot.ini file. You can accomplish this from the Recovery Console by using the copy command.[/quote]

[b]Replacing the Registry by Using the Recovery Console[/b]
Problems with the Registry can be remedied by using the Recovery Console. Registry files can be replaced by using the copy command. Backup copies of the Registry files are kept in either the %systemroot%\repair folder or the %systemroot%\repair\regback folder.

To replace the Registry using the Recovery Console, follow these steps:

1. Start the Recovery Console, and enter the local administrator password.

[b]BOOTCFG parameters.[/b]

[quote][b]Command Description[/b]
Bootcfg /add Adds a Windows OS to the boot list
Bootcfg /default Sets the default boot entry
Bootcfg /disableredirect Disables redirection of the boot loader
Bootcfg /list Lists all current entries for the boot list
Bootcfg /rebuild Searches through all Windows installations and prompts for which to add
Bootcfg /redirect [PortBaudRate] [useBiosSettlngs] Enables the redirection of the boot loader to the specified location
Bootcfg /scan[/quote]
Scans all disks for all Windows installations and displays the results

2. You will start in the %systemroot% directory (for example, C:\WINDOWS). Enter the following commands:

[code]cd repair\regback
copy filename C:\WIND0WS\SYSTEM32\C0NFIG[/code]

[i]Here, filename[/i] is the name of the Registry file to be copied.You should rename the current Registry files before replacing them. In case a problem occurs, this gives you the opportunity to return to the systems original condition.

[quote]Warning: Files located in %systemroot%\repair\regback represent the Registry state the last time that the System State was backed up. Any changes made to the Registry files since then will be lost.[/quote]

Thanks for reading my tutor… did it my self… extracted the commands by googling.
