Hi .all
I cannot boot with achi enabeled only ide mode
I installed windows 8 64 bit with ide instead of achi,is that causing my problem.
Should i reinstall with achi enabeled only? if memory serves me correctly last time i tried to do that i got a yellow uefi screen when trying to boot up ill image my setup and try it anyway.
Sarting to think these uefi boards are a headache all amongst themselves.
but i love the way asus uefi looks on a build i did for a friend

I remember doing this a while back and it worked perfectly. Pain in the arse to reinstall everything!

Do not attempt this if you do not know what you're doing!

You start with step 1 while you are still in Windows in IDE mode.

Run the Registry Editor (regedit.exe)
Navigate to Registry Key: HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Msahci
Set the "Start" value to 0 (zero)
Navigate to Registry Key: HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Pciide
Set the "Start" value to 0 (zero)
Shut down
Start up again, but before Windows boots go into the BIOS configuration screens and change the disk mode to "AHCI". Save the new BIOS...

Start up again, but before Windows boots go into the BIOS configuration screens and change the disk mode to "AHCI". Save the new BIOS configuration and restart so that Windows boots.
When Windows starts, it will detect the change, load new disk drivers, and do one more reboot to start up with them.

If for any reason the above steps should fail, simply change back to IDE mode in the BIOS.
