I had a kernel panic on my MacBook Pro, which led me to erase everything from it, and install Ubuntu 15.04 (64-bit) on it, from the mini iso, with the choice of erasing everything on the hard drive. And now I have this message screen which I don’t understand at all:
I fact, when I boot, I have a white screen, then GRUB screen shows up, I choose Ubuntu, and then I either have the kernel panic, GRUB screen again, or a black screen.
What should I do? Shall I enter in grub with a 'c' and do something in it ?
Edit. Image from the kernel panic under OS X :
As the quality is not optimal, the first line says :
panic(cpu 0 caller 0xffffff800fac0531): "unable to find driver for this platform : \"ACPI\".\n"@/SourceCache/xnu/xnu-2422.1.72/iokit/Kernel/IOPlatformExpertCpp:1541

Do you have any images of kernel panic when you had OS X? – ss4566654768 – 2015-09-21T21:59:17.840
FWIW, the key error message is, “kernel panic-not syncing: VFS: unable to mount root fs on unknown block(0,0)” So it seems like a hard drive issue. Maybe partition-based? – JakeGould – 2015-09-21T22:06:22.063
@RACING121 I do have pictures from the kernel panic happened while I was under mac OS X. I will put them in a an edit of the question – Olorin – 2015-09-21T22:08:02.287
@JakeGould Actually I've installed ubuntu 15.04 64bits from mini iso on a CD-R. I chosed automatic partionning, and when I was asked where to put grub (with some message about the need of boot partition due to my disk or something like this) I chosed to put it on /dev/sda – Olorin – 2015-09-21T22:17:54.207

Did you attempt to enter recovery mode (command-r) when you had OS X? You could of reinstalled it. – ss4566654768 – 2015-09-21T22:23:33.390
@RACING121 I did try, I even completely wipe out the non recovery partition and reinstalled yosemite on it, but the macbook was still extremely slow, and had kernel panics from time to time. So finally I decided to install ubuntu on it, to see if I will have kernel panic on it. And I had, but a kernel panic related to partition, according to JakeGould – Olorin – 2015-09-21T22:25:59.860
