A smarter installation of Windows
In order to make a qualified installation of Windows, I recommend that you have 2 Hard Drives. The second drive can be installed retrospectively, after you install Windows. Since you spend a lot of time to get a complete setup, I think you should take a backup of type ‘Disk image’ / Ghost (a copy of the entire installation and all configurations). If something fails you can restore the entire installation with all Drivers and programs, including all configurations are made. This will save you many hours. Restoring a Ghost take ca: 0,5-1 hour, a complete installation takes 20 tim. – 3 days.
