I have a MacBookPro9,2 and I have installed windows7 64bits:

  • "C" partition: Windows7 64bits;
  • "D" partition: NTFS for Data;
  • Free space to install Ubuntu 14.04;

The problem is when I try to install Ubuntu, I am surprised that the hard disk is all free (partitions "C" and "D" don't appear).

I have also tried with Ubuntu 10.10 and I have the same problem.

Thanks for your response!

  • Can you post a list of your partitions? Paste the output of fdisk -l. Do you have a mbr or guid partition table? – Jure1873 Apr 04 '14 at 21:23
  • Just a precision: when I try Ubuntu without install it. it recognize all partitions. The issue is in the partitioning step – Walid Ammou Apr 04 '14 at 21:28
  • Maybe a driver is not loaded. Do you see the disk and no partitions or nothing at all? fdisk -l output would help :) – Jure1873 Apr 04 '14 at 21:30
  • I see the disk (500 GO free). but no partitions – Walid Ammou Apr 04 '14 at 21:31
  • The output of fdisk -l command is:

    WARNING: GPT (GUID Partition Table) detected on '/dev/sda'! The util fdisk doesn't support GPT. Use GNU Parted.

    RESOLVED:Disable GPT, In the terminal while “booted” from the live CD type “sudo gdisk /dev/sda” (change “/dev/sda” to whatever is appropriate to access your hard disk). The program is likely to complain that it’s found both MBR and GPT data,and will ask which to use. At the “Command” prompt, type “x” to enter the experts’ menu. At the “Expert command” prompt, type “z” to “zap” (destroy) the GPT data.Type “y” in response to the confirmation about destroying the GPT.Type “n” in response to the query about blanking the MBR. /!: If you answer “y” here, you’ll destroy your Windows partition(s)! – Walid Ammou Apr 05 '14 at 01:52
