The OP is aggravated, so I 'get' that no being able to install an OS easy-breezy can be a little confusing and frustrating. I take none of this personally...
The underlying problem isn't ANY MOBO MFG, but instead the OS with it's OLD (very OLD) and LIMITED driver package. I have an X79 and for any form of RAID you must 'inject' the drivers essentially the same way. The advantage to Windows 7 is that installing it off a a USB Flash Drive is easier.
Therefore, the solution is exactly as I posted above.
Here's a good Guide and as good as any I've seen ->
http://www.wikihow.com/Slipstream-Your-SATA-Drivers-Into-a-Windows-XP-Installation-CD-Using-nLite ; note Steps 12-14 will need to be changed for your particular SATA driver.
* iaAHCI.inf = AHCI driver ; from the Guide
* iaStor.inf = AHCI driver from (For AHCI / RAID Mode) F6 driver download
Step 13 = "%userprofile%\desktop\sata driver\iaStor.inf"
Step 14 = not 100% sure on Z77, but should be something like "Intel(R) 7 Series Chipset Family SATA AHCI Controller"
Hopefully the OP can make use of it
