|You have a misunderstanding there, when windows install reboots, it is updating/creating the registry, but the install is not complete. if you remove the CD, it cannot boot yet to the hard drive since the install is not complete. It does actually boot to the install CD, but does NOT restart from the beginning since the install DOES leave behind enough for the system to continue from the correct point in the install.|
I have seen this many times, when the install is complete, it will tell you when to remove the install disk and click OK to restart. Then it will restart properly. There is actually NO reason to make the hard drive first in boot order, since it will only boot to the CD if there is a bootable disk in the drive.
You have to be a little bit crazy to keep you from going insane.
If all else fails, read instructions.
