EFI doesn't require GPT or other round. Mac OS X installer will refuse to install on GPT but if you force it, Mac OS X will be able to boot alright.

Windows is an exception since Microsoft pretends that possible is impossible. --=20 Regards Vladimir '=CF=86-coder/phcoder' Serbinenko --------------enigFBB9F5C432DD2DDC6EB7C908 Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.12 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iF4EAREKAAYFAk/SSWYACgkQNak7dOguQgkJFwD+PdUpESEpfMcLJ2eddQY6qsfr cE7bOL6zlUxgaaE6uM4A/1zRArcGTdfHbihWLjRqHOrR/FDz/3Vj4smyrYF8AMW5 =XgIn -----END PGP SIGNATURE----- --------------enigFBB9F5C432DD2DDC6EB7C908--
