Welcome dear members of Trap17, to my Tutorial. 
Ok, today we are going to learn how to Delete an Operating System (OS) from our OS Choice menu.
ATTENTION!: It is not my responsibility/fault if you do something wrong, or make a mistake, and your computer gets screwed!
Lets start.
First we need is a backup of boot.ini incase you make a mistake.
Please make sure you have another working OS incase you mess one up!
Go to Start > My Computer > System Tasks, click "View System Information". Close My Computer.
Now you will see a window called "System Properties".
Click "Advanced" then you see this option:
Once in boot.ini remove (delete) the OS line you want to delete; keep the OS line, you want.
Deleting both OS lines saving, then restarting, may cause problems, of unable to start up your computer.
REMEMBER!: Make sure you READ this Tutorial CAREFULLY.
Thankyou,
Kel
