Hi, Someone.
Vista didn't "change" the order of your drives. Home still sees them as it
always has. But Ultimate doesn't know what letters Home has assigned unless
you run its Setup.exe from within Home, so it starts from scratch and
assigns its own letters to those same partitions. It starts by assigning C:
to its own "boot volume", where you told Setup to install it - the first
partition on the second HD. Then it can't assign that same letter to the
first partition on the first HD, so it assigns D: to that one. But these
letters apply only within Ultimate, not in Home.
We can control letter assignments when installing a second Vista by running
the second Setup from within the first installation. In other words, if you
had booted into Home and used Disk Management to create a partition on your
second HD and assigned it the drive letter U: (for Ultimate?), then inserted
the Ultimate DVD and run Setup from within Home, you could have installed
Ultimate into U: and left C: assigned to the System Partition. I've used
this method often when installing multiple versions of WinXP/Vista,
especially during the Vista beta.
If I understand you correctly, you should be able to boot into Ultimate and
nuke D:\Windows, which will get rid of Home. But your boot process will
still start on that first HD, since it holds the System Partition, and then
find and load Ultimate from C:\Windows. If you want to retire the first HD
and boot from the second, then you will need to install the BCD (Boot
Configuration Data) onto that second HD. You can do this by booting from
the Vista DVD and using its Repair option, or you can use something like
EasyBCD from NeoSmart:
