Problem booting os x and testing offer

[James Shewey]

two things:

1) I am having trouble booting os x from grub. When I do "chainloader /usr/standalone/i386/boot.efi" I get "Error: invalid signature". If I do "chainloader -f /usr/standalone/i386/boot.efi" I get a blinking cursor and my computer does not do anything else. Any suggestions on resolving this?

2) I am willing to do any testing that might be helpful on my penryn based macbook pro. I have a BS in CS and am employed as a Linux and Mac Solutions engineer for the company for which I work. Let me know if there is anything I can do that will be helpful. Perhaps I can help to reveal some information about blessing boot images.
