Services.exe not found on bootup

Hi,
I am running windows xp and i recently renewed my norton antivirus subscription online and to complete it's installation, it told me to re-boot. I did and now my computer will not restart. I get an error message saying that services.exe could not be found and that I should re-install the application to fix the problem. I understand what services.exe does for my computer. I do have a restore point set for my computer but I cant figure out how to do that since my computer stalls at the "windows is starting up"
screen after I hit OK on the error message. I tried to run the computer in safe-mode comand prompt only but it wont give me the command prompt. Is there a way to get a command prompt screen another way because if I can get one, I know how to acess my resotre point by typing prompts. I just cant get to the point where I can enter them. Any help would be great! THanks!

 

Get your hands on a Win98 boot disk. You can get to the command prompt from it. bootdisk.com has it on there.

 

Thanks, i'm still workin on this. I'll try to find it. I plan on takin my junk laptop to my school's tech guys soon.
