controller found and freeze

I am trying to install ubuntu to my old mac. I have portioned the Memory and added the ubuntu.dmg to the USB Drive. I have tried both Ubuntu 64 and 32 bit, and so far both bring me to this image below. I have looked all over the forums and webs to try and solve this problem and have found nothing. I was following this tutorial and I edited the main config for refind, but when I ran sudo mount -t msdos /dev/Disk0s1 /Volumes/esp in a terminal the output was

Resource Busy

Picture of the screen after booting the USB.

  • @ElderGeek Theres not really much detail to tell. I did what most tutorials for this tell you. I had only one problem and it was when I edited the main config for refine, I was after supposed to run sudo mount -t msdos /dev/Disk0s1 /Volumes/esp in a terminal and the output was "Resource Busy".

  • That's exactly the kind of thing you should edit into your post. I did it for you this time.

  • What is the model of your Mac?. I just installed Ubuntu 64 bit to an external drive using my iMac 20 inch Mid 2007. If you want I can supply the procedure I used. Jun 10, 2015 at 20:57
  • The mac is a MacBook Pro (15-inch, Mid 2009). I wonder how different you the procedure you took was, to the one I took. At this point I'm willing to try any suggestions. Jun 11, 2015 at 6:21

Did you see the Ubuntu bootable usb choice on your mac? If not, the bootable usb is not created properly. You can check this link to verify you have done it correctly.

  • I tried what you said and it changed what it says depending on how I try to boot it. I get i8042: No Controller Found if I try to boot EFI\boot\grubx64.efior the penguin on the boot option.(I get the same thing if I try the Fallback option) and when I try to Boot Legacy OS from whole disk volume. I get a the original problem with an occasional usb error.(will post picture in main post.) Jun 10, 2015 at 14:08

  • Does it matter that a USB flash drive, created using the method at your link, does not verify? Jun 10, 2015 at 20:53
