I had the misfortune to use EaseUs to clone the OS drive from MBR to GPT using the clone option, not by using the clone system option. The old drive (RAID-0) still works as system drive for Windows 7, but the new drive does not. It gives an MBR error on booting. Hitting F8 has no effect.
Is there a tool or command that works like bootrec that can be used on some disk when I've booted from another disk? That is, the new drive shows up when I boot from the old drive. I figure that only the EFI records need to be fixed. Or are there steps of fixing this by using system repair from the working disk?
I can of course do the cloning again, but it took 6hrs so I prefer not to.

If your getting a MBR error your create a GPT clone – Ramhound – 2017-01-24T02:10:16.497
@ramhound, indeed. The clone is from MBR to GPT. But windows can boot off of a GPT disk, the question is how to fix it. – Abel – 2017-01-24T02:12:30.300
