I installed rEFInd on my new Macbook Air which I planned on using to do a dual boot to Linux, but prior to installing Linux, I decided to encrypt my drive. I knew I was going to do this, so I had already installed rEFInd with the --esp option.

When I rebooted after this however, it seemed to have deselected rEFInd for boot. I reinstalled, but when I did and rebooted, my Mac partition would not show up in the bootloader (only the recovery partition). I ended up needing to hold Command+Options+P+R to get it to boot again.

Any help getting these two to work together would be much appreciated.

Reading through this thread, I found some guidance for mac os 10.7 in this comment, but later comments seem to indicate rEFIt should handle most of this automagically now (a year later).

Have you re-installed rEFIt after turning on the encryption?

I would suggest getting both OSes working with rEFIt and then turning on the disk encryption.

Fire Vault against what you might expect tries to protect itself from a hack by messing with the boot order. rEFIt would have fixed that if you had installed it the other way around. Unless you are really bad with keeping updated there is no way for Linux to get viruses contrary to Macs. I still laugh for hours when people talk about how secure MACOSX is and point them to the Metasploit database. So there is no need to encrypt your disk. Keep in mind that the main security components of Linux were made by the NSA so they are almost bullet proof. If a malicious program wanted to mess with your OS FireVault is next to no good as there are a couple known exploits to break in and it is easy to erase the partition which doesn't require decrypting firevault.

This does not answer the question, and it contains factually incorrect information. –  Kevin Panko Oct 12 at 1:19
    
This is first hand information but you are right the NSA wrote SElinux a part of the security but not all. Your comment is not useful and the answer is to reinstall rEFIt or disable FireVault. I have being using that combo since Macs have the capacity to boot Linux. Installing Linux voids your warranty according to Apple. –  Hector Prado Oct 12 at 1:27

1) There are ways for Linux to get viruses. 2) Encrypting the disk protects against someone stealing your PC so there is a reason to do it.3) Anyway, just answer the question without editorializing. Super User is not for a debate and discussion, we just stick to the facts please. –  Kevin Panko Oct 12 at 1:34
    
Also, welcome and I apologize for my tone earlier. –  Kevin Panko Oct 12 at 1:37
    
Do Linux drivers contain zero day exploits when used on Macs? The Mac drivers have repeatedly been found to allow for remote control. I do agree ANY computer system can get viruses some are just more proactive about defending their users. –  Hector Prado Oct 12 at 1:52
