I have a RAID configuration on a P8Z68-V LX motherboard. I want to convert back to IDE mode. Will a Windows-7 system image work as a restore when I go back to IDE mode? Or does this system image created on RAID only work to a RAID restore.

Otherwise, what is necessary to convert from 2-drive RAID 1 back to a 1-drive IDE system?

A Windows 7 system image would not be impacted by the distinction between a RAID array and non array setup (IDE is not the proper term btw). If you make a backup or system image it should be safe to restore that back onto a non-RAID array setup.

To clarify:

IDE is commonly misconstrued as the term which actually refers to ATA, the connection method used for HDDs and optical drives. If you'll note SATA is similar to ATA, as it builds on the ATA and SCSI technology. IDE is more of a concept of internal devices than a connection method.

RAID arrays are simply a method of organizing HDDs. It would be proper to call a drive not in a RAID array an individual drive, there is no technical term for it that I know of as the distinction isn't exactly defined by specifications or any sort of thing.

You better inform the bios builders, they have been using ide mode in bios's for years! I prefer Pata and Sata. –  Moab Apr 30 '12 at 19:23
    
I'm pretty sure the engineers know what the terminology is, I suspect it was a marketting decision to use a term which would be more distinctly recognizable to represent a legacy mode. –  BloodyIron Apr 30 '12 at 19:27
    
I get it, its wrong but widely accepted as correct. –  Moab Apr 30 '12 at 19:42
    
Not sure I agree with your answer that a restore onto non-RAID will work. Windows 7 will install AHCI (incl RAID) or IDE drivers based on your bios selection. If you change the bios from one to the other the PC won't boot - Windows won't automatically detect the change and install appropriate drivers. –  BJ292 Apr 30 '12 at 20:08
    
The RAID and AHCI drivers are the same in terms of most controllers. As long as you maintain the controller in AHCI mode this should still be fine. I have yet to see a situation where RAID was enabled but AHCI was not, such drivers should serve dual purpose. –  BloodyIron Apr 30 '12 at 20:26
