First thing first, check that the jumper settings are correct. There should only be one master and one slave.
Check the stickers on the hard disk for setting the jumpers to master and slave.
The one using master jumper settings should be the one where Windows is installed on.
Don't use the cable select option if it is given, this will give problems.
Then get into BIOS (usually by pressing the Del button when it boots up).
Set the first boot device to the hard disk where Windows has been installed on.
Save the settings and restart the computer.
Mayi jie jie so smart!
