Let's first clarify what "unattended installation" means.

It can mean several stages of the installation happen automatically. ALL or just some are unattended and the program has a full unattended setting but I did not try that.

What I did try was the settings as indicated in the images I supplied.

I slipstreamed the disk. I then "popped" it into the other computer in the CD drive and rebooted. Remember that BIOS has to be set to try to boot from the optical device first.

I kept the option for pressing the "any" key to go into the windows install. The program does have a setting to bypass this if you wish.

The system had two SATA drives on the SIL3114 headers. Windows automatically installed the slipstreamed SATA driver and found the drives. The system STOPPED at that point and waited for me to choose the partition and format the drive as I saw fit. Those drives were previously partitioned but clean.

I made those two choices and everything happened "unattended" from there right to the desktop.

That was because I chose that particular setting for that form of "unattended setup."

If you choose the full unattended setup then the system assumes you are installing on c:\ and should proceed fully unattended from the time you "pop" in the disk and reboot..to the desktop.

In other words...as I said previously...just depends on what depth of "unattended" setup you configure.
