Figured I’d post this in case anyone else runs into this issue. I was performing an unattended install of Windows Home Server 2011 and the setup failed. I tried to use the same cfg.ini file again, however, setup didn’t like the file the second time around. Knowing that I hadn’t changed anything, I opened the file and noticed something strange. There was an additional line that Setup adds to the file once its used it.
The line added is located in the [WinPE] section and is called Processed=true.
In my testing, removing this line will allow the cfg.ini file to be used again.

This tip applies to:
- Windows Home Server 2011
- Windows Small Business Server 2011 Essentials
- Windows Storage Server 2008 R2 Essentials

I had the opposite problem on an HP MSS EX495. At each restart it would keep booting from USB and starting from the beginning again. I had to use a debug board and enter the boot menu to select HDD each time. After looking at cfg.ini that line had not been written.
