Glad to see you figured that one out. Even if you'd said in the
original post that your system was setup to dual boot, I doubt
I would have made the connection.
FYI, your original question was "the safe mode boot options are
shown as unavailable". Based on that statement, I interpreted
your issue to be that the radio buttons next to /SAFEBOOT
(MINIMAL, NETWORK, DSREPAIR and MINIMAL(ALTERNATESHELL)) were
unavailable. The items listed below /SAFEBOOT, (NOGUIBOOT,
BOOTLOG, BASEVIDEO, SOS) in the Boot Options section can be set
for normal boot as well. They don't apply strictly to Safe
Mode. They reflect some of the other items listed in the
Windows Advanced
Options Menu.
As for your controlset002 question, I'm no registry expert but
here's the best explanation I can put together:
The fact that one machine has a controlset002 and the other one
doesn't is not unusual. Control sets aren't always labeled
consecutively. I have one XP system here with control sets 002,
003 and 004. Another has 001 and 002. You'll see at least 2 and
as many as four listed. To get a better idea of what role the
different control sets play in successfully starting your
computer, look at the values listed under the
HKEY_LOCAL_MACHINE\SYSTEM\Select key.
The Current value points to the control set that was used to
boot the computer.
The Default value points to the control set that the computer
will use the next time it boots up. In most cases, Current and
Default point to the same control set.
The Failed value points to the control set that failed to start
before the Last Known Good Configuration option was invoked.
LastKnownGood points to a control set, other than the current
one, that started the computer successfully.
If you're interested, take a look at the "Understanding Control
Sets" section of the
following article. Though it was written for Windows NT, the
basic principles still apply to Windows XP. One thing you won't
find with XP is a Clone key.

Here are some other articles that may help shed light on your

If the above info doesn't answer your question, you might want
to start a new thread. That way, someone who knows more about
the Windows XP registry than I do may see your
question and provide a better answer.
