Windows 7: Change windows boot drive

Hi!



Okay... the situation:

Just installed Windows 7 on my PC. Formatted my Vista 200gb sata drive C: and installed x64 over it. my other two drives have music files, documents etc on them. I have previously had installations of Ubuntu and the dev version of Windows 7 that came out some time ago.

Now, after the Windows 7 installation and the pc restarted I got a GRUB loader error (the boot screen for ubuntu) presumably because I deleted the ubuntu partition. So I changed the boot order to one of the smaller hard drives and Windows 7 loaded up. So it seems whatever it is that decides what to boot is living on one of the smaller hard drives. I want to switch it over to my main C: drive where the Windows 7 installation is because I no longer have any other OS on my system. I'd like to keep those drives as seperate removable devices so if windows booting up depends on one of them and I remove it then I'm screwed!

Any ideas how I can change the boot device?

Cheers! P.s. sorry for any incorrect terminology that might not make sense. I just hope you can understand me!

Is the Windows 7 HDD installed as SATA 0 .. The first SATA port ??
When you installed Windows 7 .. Was it the only Drive connected ??

i think this is what you need:

MBR - Restore Windows 7 Master Boot Record
