Thanks theog, but I actually read about UEFI booting standards, etc, so I won't be asking ignorant questions like my first ones.
Although this is the Windows 7 forums, I'll post my experiences with an UEFI installation of Windows 8. The only guides and tools I used were those provided by SevenForums.
I purchased a Windows 8 Pro Upgrade download, and used the create media option. The result was copies of the iso file, and the ESD folder. Given the warning about potential problems with the iso when creating the UEFI bootable USB drive, I used the ESD-TO-ISO program. Creating the UEFI bootable USB drive went perfectly.
The installation went perfectly, the four partitions were created on a raw RAID 0 volume of SSDs. When I do a standard Windows 7 installation on a RAID volume, I always load the Intel "F6" RAID driver
, although that is supposed to be optional. I tried that with Windows 8, but the supposedly Windows 8 compatible F6 driver would not load. In the end no optional driver was needed, Windows 8 has what it needs, for Intel IRST RAID.
I had to perform the Windows 8 "Refresh" operation before my installation would activate, which was very simple. I would suggest not loading any drivers
you need until after the refresh, since I had to install them again after the refresh. IMO, the overall installation is not a difficult process, and the guides are flawless.
For people that are concerned about the apparent lack of drivers provided by mother board manufactures for use with Windows 8, I now understand why only a few if any drivers are provided. They are unnecessary. I installed only three drivers, one for the video card, and the others I downloaded directly from Intel, for my ASRock board. The two USB 3.0 drivers I need to load for Windows 7 are native to Windows 8, for example.
Also, IMO Windows 8 is not a tablet, touch screen only OS. Yes it is different than Windows 7, but if you really give it a chance, everything you usually use is there, just in a different manner. I have not used one of the "add the Start menu to Windows 8" programs, which forces you to learn the new way things are done. I would suggest others do the same. I may need to buy another copy of Windows 8, before 1/31...
