Question Linux on a Mac (Intel) anyone?


I have an external disk (usb) with Ubuntu Linux 12.04. I connect it to any of my Windows pcs to run Linux when necessary (modifying the BIOS to boot from the usb drive). I recently acquired a Mac Mini. I wonder if I could do the same thing, meaning, selecting the external drive where the Linux OS is located from the Start Up Manager in the Mac, and booting from it. Anybody here has experience doing what I'm considering? Thanks.

Have you plugged it in and actually opened up Startup Manager to see if it appears as an option? If it does, it should be doable. I haven't done such a thing lately, but I have in the past. Although I can't remember whether I was using a PowerPC or Intel Mac.

Thanks for answering. Sorry, it didn't work. The HD was not recognized by the Startup Manager. I think that something needs to be done either in grub (Linux bootloader) or in EFI (the BIOS equivalent in Mac), but that is way beyond my knowledge. I hope that some of the brains in this forum have done it before and can kindly pass the knowledge (if it is not too technical). Thanks.

Should boot just fine. Hold Option before you hear the Mac sound and you should get a list of all bootable devices including your external disk. It may show up as Windows.

If it doesn't show up, how did you install Ubuntu on the external drive?

In fact, the drive doesn't show up on the Start Up Manager while holding the Option key. Another thing I did was, I connected the drive after boot up and the system reports the message: "The disk you inserted was not readable by this computer."

I installed Ubuntu on the external (usb) hard drive using my Windows pc with the 12.04 iso I burned on a CD.
Thanks

Disk will not be readable because MacOS cannot read ext file system Ubuntu uses by default, but it should still show up in the boot manager.

You may need to take a look at rEFIt. http://refit.sourceforge.net/ to get your external drive to show up. Before you do, try a different USB port on the mini. Also try plugging it in while you're already in the boot selection menu.
