Ntldr run the program ntdetect.com which is use to check the hardware devices and passes this information back to the ntldr which will later be used to update the registry. Ntldr then loads ntoskrn.exe, hal.dll and the system hive(which is a portion of the registry that include hardware information that is use to load the proper device driver for the current hardware. Ntldr then passes the process over to ntoskrn.exe and the process is complete.
Thats why you can't just swapp harddrive with an OS already install on it.
I was kind of too direct about my point and not realize that you maybe able to do so If you had more then one hardware profile.
