I am trying to install Ubuntu 13.04 (the 64-bit Mac variant) onto my Mac Mini. Thus I shrunk the main MacOSX partition and installed refind. Now I can boot into rEFInd and then select the usb stick, but it does not boot due to:

Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0)

Sadly I cannot find anyone who tried a recent Mac Mini/Ubuntu version. How best to debug this issue?

Update 1:

So I figured maybe rEFInd does not provide the necessary driver and installed it again via install.sh --drivers-all. Which lead to a WSOD. Luckily I eventually could get back into restore via Command + R and am now reinstalling MacOSX.

Update 2:

After my MacOSX was working again I did:

  • installed _rEFIt
  • set up my future Ubuntu partition as FAT
  • booted twice
  • booted into Ubuntu Live CD

And that's where the next trouble started. While wireless and graphics work great in Ubuntu 13.04, they mount the FAT partition as /cdrom, which makes installing on it impossible.

Why not try rEFIt instead ?

rEFIT / Ubuntu 12.04 LTS / Kernel 3.9.x worked for me

    rEFIt seems no longer maintained!? You are talking about a recent Mac Mini with Mountain Lion installed?

  • I got the late 2012 Mac Mini 6,2 model with the i7 processor running OSX Mountain Lion. This one => store.apple.com/us/configure/MD388LL/A?#hardware

  • Kernel 3.5.x appears to have issues enabling Wired Ethernet Connection on Mac Mini 2012. Upgrade to Kernel 3.9.x fixed the issue.

  • Also had low color issue with HDMI graphics. work-around: 'sudo pm-suspend'

This is a somewhat complete guide that I wrote to help you all brave tux users to make the whole Ubuntu/Linux mint installation process a breeze. I try to address all the issues I had with wireless broadcom drivers and power management.

Have a read and post comments if something is not right with the document..
