Recently install perfectly OSX 10.8 using myHack 3.2.
Install went with no problems and on the first boot I got the boot0:error. Following the guide on this forum I used the boot1h fix on the bs to equal 4096 then it booted fine and perfect.
Been running perfectly ever since but now I really need to get it dual booting with Windows 7 that's where the problem started.
I split the osx install in half to make a 2nd partition to install Windows.
As always I put the Windows install onto a USB stick for faster installing and booted from it but now it just stops at (Starting Windows) before it even gets to the installing part.
Tried other OS's to see if boots; Ubuntu wont load at all.
The bios settings for the motherboard have been set right for both osx and windows with main on being AHCI enabled (was my old board and worked perfectly then installing Windows via usb with AHCI enabled)
Did a test and used the same drive with AHCI disabled and them the usb install worked
Tried a old spare drive with AHCI enabled again and this time the install worked.
Does anyone have an idea if or how the OSX install could have somehow stopped AHCI installs working on this HDD?
