I have here a desktop with two sata drives. The first one (C:) has XP
and the second (D:) Windows 7. If both drives are connected to the
machine, it will boot XP; to boot Windows 7 I have to remove the XP
drive which is a bit of a drag. So, I would like to be able to select
which OS the machine will boot from.

Searching online I find tons of examples of setting a machine whose
primary (for a lack of a better word) OS is Windows 7 to dual boot
with XP, which is exactly the opposite of what I want to do. Short of
installing grub, is there a windows way to do this? I was also told
that editing a boot.ini file in the XP drive would do the trick, but I
could not find the said file. What else should I try?

I thought about this before and wondered if one was to control the DC
power to each drive from switches at the front of the computer (just a
simple, single pole switch would work), would that control things well?
If there is no power going to the drive it won't be detected. It would be
like its not there. As Sata doesn't have the Master/Slave, jumper
idiosyncrasies of IDE, this might work. I wouldn't do this with IDE of
course. Opinions?

Did you go in the BIOS and change the boot order so that the Windows 7
drive is the first hard drive in the boot order and see if you can then
boot the computer to the Windows 7 while the other drive(s) are still
connected?

Well, I see the main problem is that Windows 7 was installed to the
second drive without the XP drive being around. So, it could not edit
the boot menu. Can I do that after the fact? I have no problems
swapping drives around or maybe editing the drive order if the bios
supports it. I just want this to work.

Yes, set the Windows 7 drive as the boot device in the BIOS then add the
Windows XP installation to the Windows 7 BCD store. You can use the
Windows 7 BCDEdit tool to add Windows XP to the store or you can use a
more user friendly tool like EasyBCD http://neosmart.net/dl.php?id=1
