I'm not sure if I am reading this correctly...

First you say you backed it up and then you say you copied it.
(A backup would be restored, and/or an Image would be restored...)

I "think" you backed it up (or Imaged it?) while it was in use as a
data drive, so when you restored (or copied it??) it came back
as a data drive with the same letter it had...
I don't think I would have done it that way, or from with-in ANY
version of Windows... (Personal preference: I use both Acronis
and Ghost, both from outside Windows ONLY...)

As a guess, only if you can afford to loose the "E" drive in question.
(It is a copy, correct?, with no other "extra" data??)
In a situation like this, I would first get the drive installed BY ITSELF
in the system... (Fix the jumpers etc...)
This is a precaution against "whacking" the wrong drive, as the drive letters
sometimes switch around in some of the lower level type utility programs...
(If there is "only" one drive installed, it is a pretty good bet you can not
select the wrong one... <grin>...)

I would boot to the recovery console and "do" a fixmbr and/or
a fixboot command.  If third party partitioning software has been used
on "any" of the drives in question you "might" get some pretty scary warning
messages... (Do not proceed unless you can afford to loose access to the
drive and all the data on it...)
