Can't Get to Chimera Boot Screen

[darx86]

I was dual booting with Mac OS X and Windows 7 without problem. Yesterday I installed a wrong kext file and need to reinstall the Mac OS X. I used unibeast usb for reinstallation. However after installed the new Mac OS X, the chimera boot screen was gone and it straightly went to Windows 7 even I reinstall chimera from Multibeast. Anybody knows how to solve it? Thanks.

Boot with your OSX installation media, and reinstall the bootloader. That done, be sure the OSX HDD is chosen in BIOS as the primary boot.

Best regards!
