Disable secure boot in BIOS - Windows does not like hardware changes.

OK, try this.

In Clover config.plist under the boot args there is an entry

<key>Legacy</key>
<string>PBR</string>

change it to this

<key>Legacy</key>
<string>LegacyBiosDefault</string>

then in BIOS set the OS X drive as first in BBS boot order and the Windows drive as second, save&exit,continue boot - select the Windows icon at Clover screen and see if that works for you.

Thanks for all your reply but when i tried to do this windows go to LAUNCH STARTUP REPAIR tool and i can`t even use my keyboard to choose START WINDOWS NORMALLY. after entering to launch startup windows would say they cant fix the issue then restart... but once i disconnect or make the windows SSD as the primary boot it works well its just that when i boot on clover this happend... BTW i even tried to do a fresh install of MAC Os....please helppp!!

In BIOS - BIOS Features tab - Windows 8 Features - >Set to Other OS

Is Windows installed UEFI or legacy mode?
If UEFI, use Clover for boot loader, set OS to Windows WHQL and disable CSM support in BIOS.

windows was installed first and i think it uefi but on booting it will be legacy.. bec when i check it it say efi... and last thing after the kernel my screen just show a white stop sign..
