Multi boot with mac mini

Sbrizzu · 12-23-2011, 07:35 AM

I've installed 3 O.S. in my mac mini, but only mac os x works well. I've understood that is a problem with the MBR partition table, wich can see only 4 partitions. My first 4 partition are the efi, mac os, recovery hd and linux swap, obviously only mac os is a real bootable partition, in fact when I try to boot from the others it only says: "missing operating system", wich seems legit. How can I change my partition table to make mbr see my O.S.? Like changing their order, or set the others as non-primary?
Please help!

I think you are mistaking one of those first four because to have more, one of those has to be an "extended partition". But maybe mac uses another logic.
Anyway, in the case GRUB would be compatible to such a partitioning format, you should install it in mbr then it will load you linux.
I don't know if chainload of a apple is possible.

I know the use of the EBR, but I don't know how to do it

. Anyway I wiped out my HDD and partitioned again inserting the windows partition as the third, so it works now!
