Hello everyone!
After I had installed Mountain Lion via UniBeast on my Hackintosh, I decided to follow this guide to install Chimera onto the 200 MB EFI partition.
It all went well, until I tried to install Windows 7 Professional on a 350 GB NTFS partition I had previously created during OS X installation.
Obviously this installation made my computer booting Windows at startup (instead of Chimera).
So I booted into OS X (via my UniBeast USB Key) and marked the EFI Partition as "active" again.
The problem comes here: now, every time I power on my computer, a black screen appears and says "Missing operating system". The UniBeast USB key is the only method I can use to boot Windows 7 or Mac OS X.
I tried first to re-mark the EFI partition as active via OS X terminal, and then even to delete my windows installation, with no success.
How can I make my computer booting Chimera again?
Thanks in advance for your support.
