Confuses a LOT of users! :^{
But read KB 314470:
Definitions for system volume and boot volume
http://support.microsoft.com/kb/314470/EN-US/
That KB has not been updated for Win7, but the rules still apply, as they
have since at least Win2K.
One thing that HAS changed in Win7, though, is Setup's assignment of drive
letters when Win7 is installed by booting from the DVD. When we boot into
an existing Windows installation, then insert the Win7 DVD and run Setup, it
can "see" the drive letters that have already been installed by the existing
Windows and use those letters for the new Win7, just as Win2K/XP/Vista did.
By assigning letters before running Setup, we can easily put Vista into V:
and Win7 into W:, if we choose.
But when we boot from the Win7 DVD to run Setup, it has no idea what letters
may have been assigned in the past. Setup starts with a clean slate. In
this situation, Vista (and prior) assigned C: to the System Partition. But
Win7 Setup first assigns "C:" to its own BOOT volume - where it installs
Win7 - even if that is the 3rd partition on the second HDD. Then, if the
System Partition is not the same as C:, it will assign the next letter,
usually D:, to the System Partition, which is typically (but not always) the
first partition on the first HDD - which the previous Windows installation
probably still refers to as C:. This doesn't confuse the computer or
Windows, but it does confuse a lot of users.
