I am in the process of re-configuring my XP machine from a triple boot when I got this on the post up screen "INVALID BOOT.INI BOOTING FROM C:\WINDOWS". If you google this one will find a ton of info but none of it would work on my machine except for one little tidbit of info from Neosmart, where Easy BCD comes from. I was finally able to trace down the culprit from a folder entry put their by Easy BCD. Finding and fixing are two different things, I have an older XP machine that I use in my shop and I had to copy and paste the ntldr, ntdetect, and the boot.ini onto a thumb drive and copy the ntldr and the ntdetect to the root of my C:\ and copy and save the boot.ini from the old machine to the one I am re-configuring. It is now booting normally. I was then able to delete the unwanted folder.
The moral of this post is be careful of how you use Easy BCD.
