acer

i have been thure this and thure this and not seeing the anser to my problem i suspect it is something with acer

what is hapeing is i go thure the steps but in page 3 i cant put in the install disk for vista because i dont have one all i have is a recovery disk that will wipe it and reinstall vista i managed to get back into vista by just reinstalling it and i did get it to show the boot loader screen with xp and vista but when i click xp it goes to the missing ntldr error and i have reinstaled it 3 times and can even see it listed there im shure its something simple i am missing but its getting to be frustrating as i am shure it is for you to keep seeing the same quistions im just wondering if there is something you might be able to think of
