Help...NTLDR missing on xp!!!!!

[Dragon]

i used the rceovery CD and did write new boot sector once (fixboot is the command i belive) but other times after getting the BSOD (yes, in XP) for different reasons, this didnt work. i think it depends on what you did as to how you fix it. or, in my case, if it can be fixed.

i learned most of the stuff i know from trial and error. school wouldve been cheaper.
