In a UEFI system, the bootloader - or at least its first component - is supposed to be located in an ESP partition on the disk containing the OS to be booted.

#Installing a bootloader for windows/mac install

The recommended workaround seems to be to first install a boot manager like rEFInd, bless it, and then use it to boot the Linux installation media in UEFI mode:

But there's one Mac-specific thing you should be aware of and, if necessary, work around: the System Integrity Protection.Īnother unique problem to Mac UEFI is that configuring it requires Apple's proprietary bless command.

So, if your Intel Mac boots the RHEL installer using legacy BIOS mode, then the installer is automatically pre-disposed to make a legacy-style installation.Īs far as I know, Macs don't use Secure Boot so that's one less problem compared to modern PC hardware. legacy) by determining which mechanism the installer was booted with. The problem might be that most Linux installers, including RedHat, will determine the type of installation (UEFI vs. I’m attempting to install Linux on its own separate hard drive in the Mac Pro, which has three other drives in the machine,ĭisclaimer: I've done a plenty of UEFI Linux installations and have a Mac, but I haven't so far tried to actually install Linux on Intel Mac hardware. I’d like to know the specific details of the best formatting practices also - what file system should the EFI GRUB partition be?

RH appears to only “see” the Mac’s ability to emulate a BIOS legacy mode during a DVD-based installation, and completely ignores the fact that Macs are in fact EFI based machines, and thus boot much faster and work better overall if RHLinux were installed in such as way as to produce a GRUB loader on the EFI partition (which is present on the disk) that boots in UEFI mode, rather than legacy BIOS mode. My host machine happens to be an Intel Mac (which is basically an EFI based machine for fastest boots - which I want - but also has the ability to boot in legacy BIOS emulation mode which Macs can use if they are installed with Windows and set to startup to a Windows partition - which I DON”T want to do.) the recommended partition scheme, and the commands) that I need to do to install RHLinux on my machine so that a UEFI installation of the OS results (NOT a “legacy” bios-style installation). I simply want to know the specific steps (i.e. How can I tell the installer to create a UEFI Linux installation on my Mac (or anywhere for that matter), rather than a legacy BIOS one?Ĭould someone please answer this question? the /boot (not LVM) 4 gig, / (root) 60 gig LVM, /home 500 GB LVM, and swap 128 GB LVM, which all still resulted in a legacy booting system, not UEFI.

I read in the DOCs that a UEFI RedHat Linux install needs a EFI boot partition, and a GUID partition map for the rest of the drive, and I prepared that for the drive I wanted to install Linux on on my Mac.ĭuring installation, I chose manual drive setup, and selected the EFI partition I had created earlier, and set formatting of it to vfat, and manually added the other required partitions i.e.

(I already tried installing on a BIOS-based PC I have here, and that results naturally enough in a legacy BIOS style Linux install, with no extra options being visible as far as I could see from the install that I went through on my Mac.) I don't have access to a modern UEFI-based Windows machine to do the installation there, and transfer it to my Mac. Trouble is after going through the Linux install in that way, the installation that follows produces a legacy BIOS configured Linux installation - which is not what I want - I want it to be installed in UEFI mode, so that I can select it with an EFI-based Mac boot loader (in particular, Clover), in a triple or dual boot situation on my machine.

I've found it won't boot to a USB OS installation stick, but, the standard RedHat DVD iso will boot, though only after a bit of coaxing, and waiting (and pulling all the possible alternative boot drive options from the machine) as Macs are natively EFI based machines, and will only boot in a legacy BIOS style after a longish wait, allowing them to support Windows.
