error 0x0000007b.repairing OS didn't work

Hi,
I think I accidentally broke my laptop :\ i tried researching this and i can't seem to find similar problems with solutions. Please help when you have the time.

I have an old Sony vaio laptop computer running SP3 windows XP. I stupidly typed MSCONFIG and put it to NORMAL startup mode. I restarted it and it just keeps restarting itself after the Vaio start up screen. Then it automatically goes to where it ask me if I want it normal, safe, etc. and I choose normal, safe, etc and it repeats itself. I did the disable automatic restart and this message came up:


A problem has been detecetd and windows has beens hut down to prevent damage..
If this is the first time .....
....
...
technical information:
*** stop: 0x0000007b (0xf7973524, 0xc0000034, 0x00000000, 0x00000000)

I tried researching on how to fix this and http://www.theeldergeek.com/stop_error_messages.htm link didn't work. I tried to have my friend fix it but he said his recovery disk didn't work. Anyone know how to fix this please?
Thank you for your time.

 

update: i researched some more and followed this:

the only problem is this: copy c:\windows\repair\system c:\windows\system32\config\system

it won't let me copy it says files not found in the system. i went ahead and exit and boot it to safe mode but its not letting me and says windows could not start because the following file is missing or corrupt: \windows\system32\config\system
