Operating system won't start!

[DeathscytheX5]

Hello all.

I have a serious problem here with my computer.

When the Operating System tries to load, right after the XP professional loading screen, the computer restarts.

If I press F8 at the start-up and choose the option 'Don't restart computer on system failure' after the XP screen, a blue sceen appears with some error like 'error occured at (0000????) x (00000000) system ended.

I belive I know what the problem is,

I can recall that one of the last things I did (which was kinda stupid ) was that moved the dll file 'secur32.dll' from the system32 folder and into a new one.

Here I renamed it secur32.dll[system32] with the intentions of returning it.

I was tryng to get rid of a program that I could not delete, one of its dependancies was secur32.dll so I moved to another location so that it could not read it.

When I restarted the computer it could not load again!!!

I then learned that secur32.dll was essential for the OS to load.

I was wondering if there is some way to:

(1) Read the file from a floppy at the required time.

(2) Run the OS in some MS-DOS or command prompt mode where I won't get the error and may be able to copy back to file to the required place. (Note: I treid all the options at the F8 screen)

(3) Download files from internet to make a start up disk to run the secur32.dll or copy it to its place.

Please help me quickly someone!

I shall post if needed the error on the blue screen.

Thank you for your time!

make a BartPE cd boot from it and return the file to its original location.

If you don't have a machine you can make a bartpe cd on, then try a repair, or using the repair console.

DOSNTFS disk will be faster and easier to make than a BartPE... and it serves the same purpose.

If your system partition happens to be FAT32, then it's even easier. Any DOS bootdisk will be able to read it.

After booting to a command prompt you can copy the file back.
