Thanks SO much. This was exactly what I needed. I was
cloning a partially bad drive to a new one using xxcopy.
I also did FIXBOOT and FIXMBR (not really knowing what I was doing) and the new disk was still not recognized for booting. All it needed was to be declared ‘active’. A little prayer (ok, a big one) and your solution and viola!
Now my computer is booting off of the new disk!

Thank you. The cmd part I did not know.

To Eric (though I know this is a wee bit old by now, and therefore probably too late):

Boot from something like the Ultimate Boot CD or else a live Linux distro, and set the correct partition as active from there – that should take care of your issue, I believe.

How do you undo this action. after setting it to active my PC will not boot. I have to boot with the windows disc in.

Thank you, this was very useful! I am transferring files from one drive to another, and this has saved me loads of grief.
