|What do you mean by "i just updated my explorer"?|
Do you mean you did an update of Windows , or you updated to the latest version of Internet Explorer? Maybe something completely different?
How did you go about updating whatever it was?
Can you use a Linux Live disk to access the files and check the BOOT.INI file? That may be the culprit.
Without knowing exactly what you did, I can't offer any further suggestions.
