NTLDR No Longer Exsists Why?

Why do I get the dreaded �NTLDR is missing, press any key to restart� error?

At boot-up, the BIOS of your computer tries to locate the primary hard drive�s active partition to read the first sector for the Master Boot Record and uses that info to load the rest of the Operating System. In the earlier versions of Windows i.e Windows NT /Windows 2000 and Windows XP the MBR is pointed to the NTLDR or New Technology Loader. The �NTLDR is missing, press any key to restart� error can occur for a variety of reasons including when the BIOS didn�t look for the right drive, didn�t find the MBR, or the MBR didn�t list NTLDR in the right place or the location of NTLDR changed.

But Windows Vista does not use NTLDR

That is right. Windows Vista does not use NTLDR. Then why does Vista throw up the NTLDR missing error? According to the official microsoft site Microsoft say the NTLDR missing in Vista error can occur only if you have migrated from an earlier version of windows to Vista that too only when you have used some imaging software to install the earlier windows version. "Not sure this is the only way because I got the error from a clean install of windows vista premium"
