Hi fellas, I have been trying to install W8 in dual boot in EFI mode on my Acer S3 and not having much luck. My first OS Mav is already installed. I tried to install W8 second and it won't install complaining about not being able to create partition or 0xc000005 error. I finally installed it using this method: osx86.net/topic/18571-guide-add-full-gpt-boot-win-8-to-your-hackintosh-the-easy-way/ But the W8 boots ups as pro version therefore will not activate or accept my OEM bios key. I'm using an iso called HRM_CCSA_X6.iso with a hash of: 1CE53AD5F60419CF04A715CF3233F247E48BEEC4 I think this is a Non-pro version iso but don't know why it keeps installing as pro Can someone offer some advice? Thanks in advance.
