#115 Triple Boot, multiple Hard drives


I have a Mac Pro 4,1 2009. It has 4 hard drives installed, with Ubuntu 12.10, Mac OSX 10.8.2, and Windows 8 Pro x64 split on them. Here is how it works:

Drive 1: Two Partitions, one Mac, one Windows. Both are bootable in Bootcamp and rEFIt.
Drive 2: One NTFS partition. For Windows programs. Not bootable, though rEFIt seems to think it is...
Drive 3: One Mac partition.For Mac programs. Again, not bootable, and rEFIt doesnt see it (which is good!)
Drive 4: Ubuntu 12.10. rEFIt sees it, but when I choose to boot from it, it instead boots Windows. Dafuq?

So I really need 2 things fixed if possible, via patches or workarounds, or whatever. I need to somehow make rEFIt stop seeing Drive 2 as a bootable drive, and make Ubuntu bootable. I am willing to test beta versions if needed. Thanks everyone.

    I should note that I installed Ubuntu by removing the other 3 hard drives first, so no boot managers or anything were fiddled with!

    You need to do 1 of the following to get the multi-harddrive support from rEFit (where the BootCampHD NVRAM variable is modified to point to the hard drive containing the selected legacy OS):
    a) recompile refit.efi
    b) use the refit.efi that I recompiled myself at
    c) try rEFInd instead of rEFIt. rEFInd has current support where as rEFIt does not. If you use rEFInd then you need to remove rEFItBlesser, edit it for rEFInd, or edit the one I created at

    You can also use EasyBCD to modify your Windows boot menu so that each Windows partition can boot the other Windows partitions.

    rEFInd might have options to hide partitions.
