I installed a new 80 hard drive, then started to install XP Pro. During the file set up, I got this message "NTLDR is missing" press cntrl alt del to restart. I want to start the XP pro install all over again, but I can't because this is all I get. I've tried to boot from CD etc. Can't I just reformat and start again?

Is this a full version XP CD?

Are you attempting a Clean Install?

This is a good guide:
