BOOTMGR Not found?

I have an ACER Aspire 5733Z that I had to install a new hard drive in because I dropped my computer and SMART was tripped. Now when I boot up it gives me the error BOOTMGR is missing. I can't boot to my Windows 7 CD either, why is this?

Can you boot in to the Windows "recovery environment"?. If so try these steps:


"Bootmgr" is the boot sector, so basically your windows files have become corrupt, this probably happened when you dropped the laptop (don't kick yourself we've all done it once).
