Re: Additional hard drive

If you install the new OS with the old HD disconnected,
the installer will see only the new HD and it will set the
newly installed OS's partition to be called "C:". When
the new OS runs, it will call the partition containing the old
OS "D:" (assuming that there are no other partitions). This
is OK unless one or the other HD has shortcuts that refer
to files on the other HD. While the new HD is the only HD
in the system, its OS will boot regardless whether it's Master
or Slave (assuming it's not Western Digital). With both HDs
connected, unless you reset the BIOS so that the HD boot
order puts the Slave HD at the head of the HD boot order,
the HD which is set as Master will boot (or, more accurately,
control the booting). Thus, you can control which HD controls
booting by resetting the HD boot order in the BIOS.

If you install the new OS while the old HD is still connected,
the installer will set the new OS to call its own partition "D:",
and it will set the boot.ini file on the new HD to dual-boot -
that is, you will be presented with 2 options from which to
select at boot time, each one designating one of the 2 OSes.

You could also just clone the OS from the old HD to the new
HD. That will give you 2 OSess, each calling its own partition
"C:" when it's running. To dual-boot between the two OSes,
you can either reset the HD boot order in the BIOS, or you can
put a 2nd entry in the boot.ini file of the Master HD so the loader
will let you decide at boot time. If that is what you want to do,
post another question on how to make a clone.

BTW, "boot device order" sets the TYPE of device that will
control booting, and the "hard drive boot order" sets which
hard drive will control booting.

I want set new HDD as primary and old HDD as secondary,
so new HDD need be set as Master and old as Slave? I need
install new OS on new HDD(via booting from CD), need I
change something in BIOS, or system will boot this Master
HDD as first Boot Device and there is no necessity to change
anything in BIOS?
