I have windows 8 Enterprise x64 RTM, an asus sabertooth z77 mobo.
I have installed windows 8 in AHCI sata mode and it works flawlessly but I have a solid state drive for caching.
So I backed up my data, changed to RAID mode in BIOS and proceeded to reinstall. Windows 8 installer sees my harddrives in raid mode and continues to install fine. And that's where fine ends.
I get blue screens before the personalization screens start "winload.exe is missing or corrupt". Randomly this morning it just worked, I got to my desktop and started installing drivers - worked fine. Installed RST 188.8.131.524 (beta) - rebooted and bluescreened "a required device is missing or failed".
Now this is where things are unexplainable for me. If I boot to my installation media and quit it at the first chance, the system reboots and boots into windows 8 flawlessly. When I shutdown or restart windows - at the next boot it bluescreens but if I boot from my installation media and quit, then it restarts and boots fine.
