Two O/S, how to remove one??

English isn't my first language so bear with me as I'm trying to make it clear as possible.

My old computer shuts down all of sudden and I had to turn it on then there was an error message saying theres some damages to my OS. I couldn't log on to windows at all. I was stuck, so I took out my win xp cd to try to repair it. I don't know anything about formatting or partition (unsure what it means) I guessed and selected delete partition or something and it installed fresh win xp and it worked. My old computer is working until I restarted the computer and I noticed that there are two OS, one is fresh and other one is the damaged one. Im able to log on with new win xp, but couldnt log on the other, same way it was before I tried to fix it. I need to remove the damaged one. Do I start over again and select format but what does it look like ? NTFS ? Im guessing NTFS means formatting to erase everything including any damages and start fresh with new win xp. Is it safe to do it again? I would appreciate any help!

 

Go Start> Run type in 'msconfig' without the quotes and go to the boot.ini tab and remove the second entry and reboot. It should be gone. That's it! BTW, you're English is better than many folk who's language is supposed to be the primary one.

 

I selected the second o/s but where to click on to remove because I don't see where... btw thanks for helping!

 

Actually, just click "Check all boot paths" in the same tab, that should get rid of it. Sorry, I'm tired.

 

doesnt work. I still see two options, one fresh and the damaged one to start windows during start up. I guess I should start over again and select NTFS this time instead of partiaian or any other options.
