Hi Chris,

Sorry for insist a lot but, I will really appreciate your help. Do you have any news about this. Did you dislike the docs document. I can post the results here in the blog if you wish.

Regards and thank you,
Gabe

Hi Chris,

Sorry for not answer you earlier. I had a lot of work to do, and I thought that maybe your answer would be forwarded to my email. But didn’t.

Anyway, here are the details:
1. Yes I’m trying a 64bit system. How do I check if it is a 64bit EFI?

2. I used a Mac Installation disk to remove the current system and the RAID set (I was wondering if it was a problem with the RAID). So right now there is no MAC OS installed on the Machine. However, when I trying to install the Linux OS, no disk appears again.

3. In the link below you could find the result of the “dmesg” with the live OS. I attached some pics with the no disk message and the current mac os utilities. (you are able to edit and comment the doc file.)

Please let me know what else I can do in order to install linux on this machine.

Thanks for your help,
Gabe

Hi Gabe,

It should be possible, but unfortunately I don’t have access to the hardware any more so it’s hard for me to test and keep up-to-date with it. So do you mean you booted the Fedora installer (or live CD) and couldn’t see any disks? If you can boot a Fedora or Korora live CD and post some results like dmesg it would be helpful to see what’s going on.

Also, are you trying 64bit system? Is it a 64bit EFI?

Hi Chris,

I have been spending a week trying to install a Linux Distribution on my Mac Pro 5,1. The main reason is that neither Fedora 18 nor Ubuntu12.04 recognize my Hard disk drives. First, I tried with only the main Hard Disk (That have Mac OSX10.7.5) in the system, then I tried with a new hard disk in the system and again the no disk detected or the no devices detected message appears while installing.

I Have rEFit on the macOS system so I can boot both Fedora and Ubuntu even when I have onle the new hard disk(So refit no appears), but then no disk appears. I tried the frisk -l command but nothing was shown.

Any suggestion of what I´m missing to achieve install linux on this mac. Or is it not possible to do it?

Thanks,
Gabe

Try Ctrl + Alt + F2 (the function key).

If not, you can try and sync via the refit menu by pressing across arrow to the partition option.

The Control-Alt-2 doesn’t bring up a terminal window so I can’t turn boot to off using parted. Don’t know how to do it from the rEFit menu. This must be a very important step (#3) because the fresh Fedora installation doesn’t boot.

Hi El,

You’re on the installer CD, which is running as root

Thought I just add, sudo didn’t seem to work when trying to run the parted command on the terminal window under Live Fedora. It didn’t recognise the sudo token.

Thanks Chris,

just have one more query, how do you manage to run the parted /dev/sda command when you’re not the superuser? I mean if you’re using the install DVD you aren’t by definition..you’re a live user…sorry I’m new to Linux !
