Vista and 7 used slightly different boot methods to get to their WinRE. I find this great because Vista was a pain to do compared to 7. Anyways, the System Reserved partition may not be 100% required, but since creating it with a recovery partition is required (for support purposes) I never tried to deploy it without one. But yes, the SR partition is marked as active. The order should be: 1. System Reserved 2. Recovery 3. Windows The reason why it boots into Windows and not WinRE each time is because the WinRE partition is marked as a hidden boot volume. So in this case, the BIOS of a computer picks the first available boot volume, the one with Windows on it because it can't see the WinRE partition. The reason to put the recovery partition first, or the service partition even back in XP days at the beginning of the disk did have some sort of reason for it. I forgot it by now. But you can definately have a recovery partition after the OS volume, for example I always installed the SoftThinks recovery partition (for XP) at the end of the disk just because it was easier to do, and they didn't seem to care what partition it was when dealing with support issues. It would appear that none of my Microsoft documentation talks about the relevance of the location of the recovery partition.
