BOOTMGR Missing! Rstoring windows Doesn't help

I recently upgraded my comp i got a new MB a Gigabyte GA-A55M-DS2 and as this MB only had SATA ports i got a new SATA HD as well I used my old MB to install windows on new HD and copy user info etc. It booted fine on old MB but when I installed my new equipment and booted it it said BOOTMGR Missing.
First I tried using windows repair but it couldn't find anything wrong with it so i tried restoring windows but when this didn't work either I swapped the MB's back this time when tried booting with the new HD it came with the same error so I booted with old HD formated the new HD and reinstalled windows but this before i installed it it came with a warning message saying the HD didnt support booting I tried installing windows anyway once again it worked with my old MB but when I used the new one it said BOOTMGR Missing.
I'm totally flumoxed can someone please help!!!

I highly recommend that you install that new motherboard and new hard drive in the PC and install Windows clean on it. The boot manager could be just the start of the problems.

If you installed Windows on the new drive connected to the old motherboard then all of the drivers are for the old motherboard. You might have to perform a Repair Install to get the correct motherboard drivers installed to use the new motherboard. Even then you will have old drivers and phantom devices in your system. Messy, not clean, which could lead to odd problems in some cases.
