Description of the Windows XP Recovery Console for advanced users

Unfortunately System Restore cannot be run from the Recovery Console - it can be run from Safe Mode .....

How to start the System Restore tool by using the safe mode option with the Command prompt in Windows XP

tiumflt.sys is a Texas Instruments file.

I am hoping that you have a current backup of your important data or possibly a disk image?

 

You may be able to get a CD from DELL, but for your purposes if you can borrow an installation CD at the same level that should suffice for accessing the Recovery Console.

 

My two cents....
UNMOUNTABLE-BOOT-VOLUME error often means hard drive issues, however since you mentioned some infection....
...some infections may cause your computer to display some error messages, which are not really what they're.
Say, in your case, the error may indicate bad drive, but it may be simply a malware causing that error.

You can try to use system restore from recovery console, but you have to remember, that system restore won't cure any infection.
However, if the infection is the culprit here, using system restore may make your computer bootable again.
Here is how to use system restore from recovery console....

If you have Windows XP CD... (if you don't have Windows CD, scroll down)

1. Boot from the CD.
2. When the text-based part of Setup begins, follow the prompts. Select the repair or recover option by pressing R:



3. You'll find yourself at this screen:



4. Once you are at the Recovery Console you will be given at least one choice of Windows installations. Normally the choice you want is the number 1 choice. Click the number 1 key at the "top" of the keyboard and click enter.

NOTE: at this point your numbers to the right of your keyboard are turned off. If you insist on using these keys for your numbers remember to hit the Numbers Lock key before clicking a number over there or your computer will automatically reboot and you will have to wait through the previous steps to get back to the console.

5. You will be given a message asking for the administrator password. Unless someone or something has messed with your computer there is no password so you just click the Enter key.

6. This will bring you to a prompt that says:

C:\WINDOWS>

7. Type:

cd \

Press Enter

Note: between "cd" and "\" there should be a "blank space" otherwise the command won't work

8. The prompt should now say:

C:\>

9. Type:

cd system~1\_resto~1

Press Enter.

===============================================================================

Note: If it gives an error "Access Denied " while accessing the folder, follow the method below

Type: cd \

Press Enter

Type: cd windows\system32\config

Press Enter

Type: ren system system.bak

Press Enter

(note the spaces between ren and system, and then between system and system.bak)

Type: exit

Press Enter

now the computer should restart, then follow steps 1-9

===============================================================================

10. Type:

dir

Press Enter

NOTE: When you hit enter it will list all the restore points folders like "rp1 ", "rp2" we have to see the last restore point to copy the file from a recent backup. If the restore points have more than one page then you have keep on hitting the key to view the last restore point folder.

NOTE: It is a good rule of thumb to choose the files from the restore point folder which the second to the last one.

11. Type:

cd rp{with the second to the last restore point number }

Press Enter

Example: cd rp9. if rp10 is the last restore point

12. Type:

cd snapshot

Press Enter.

NOTICE: Now the command prompt will look like this:

c:\system~1\resto~1\rp9\snapshot

Note : restore point 9 assumed for clarity of the content.


13. Type:

copy _registry_machine_system c:\windows\system32\config\system

Press Enter

14. Type:

Exit

Press Enter.

Final note : If the above procedure won't solve the problem, repeat all steps, but in step 13 type:

copy _registry_machine_software c:\windows\system32\config\software

Alternatively, select different restore point.
