Ubuntu 14.04 installer doesn’t show existing partitions

Ubuntu ne détecte pas la partition de Windows 7

Opening terminal and running the command

$ sudo -s
# gdisk -l /dev/sda

Indicated that you have both MBR and GPT tables present. This happened because you had originally Windows 8 pre-installed on my computer. Windows 8 uses GPT scheme. You installed windows 7 over it. Windows 7 is using MBR and finally your disk end up being MBR with some stray GPT data on it.

This is a known problem and can be fixed using FixParts

fixparts /dev/sda

The program will detect the problem automatically and propose solution.

The program is readily available within Ubuntu 14.04 live usb.
