Invalid BOOT.INI file, NTDETECT failed

Hello, everyone.

When I turn the computer appears to boot error (Invalid BOOT.INI file, NTDETECT failed) and not start Windows Vista Ultimate SP1 ... We tried to repair several times, but no use ...

I wonder how can I do to fix this, or I will have to format all over again? (I was that before and I format but did not want the new format, I spent more than 1 day to restore all my programs ...)

PLEASE PLEASE PLEASE !!!!! !!!!!!!!!!!!!!!! !!!!!!!!!!!:crybaby:

Assuming that the machine so has the view, put the DVD format and as if you were doing instead of "install now" click "repair your computer." then begins with the startup repair.

but I do not understand this boot.ini. you dual boot with XP?

I don't have dual boot ...
I only got the order ...
I noticed several times and gave error ...
But I will see if I can.
Thanks for the help.
