I needed to resize my Boot Camp partition so I used Gparted to move and resize it. This seemed to work, except that now I can't boot into Windows.

I can boot into OS X just fine. OS X can recognize the Boot Camp partition and view its contents. When I try to reboot into Windows, however I get the message:

> 
> No bootable device -- insert boot disk and press any key
>

The only solutions I've been able to find online suggest that the only way to fix this is to either clone the drive or remove the Windows partition and re-install it.

Is there any way to fix my Windows partition so that I don't have to reinstall Windows again?
