Hello,
yesterday I tried to install Ubuntu 14.10 along side Windows 7. But the installer didn't detect my Windows 7.
Windows 7 is based on a BIOS (not UEFI) and the first OS on this SSD at all. I also have ~40gb unallocated free space for ubuntu... (see screenshot)
Following outputs from sudo fdisk -lu and sudo parted -l
parted error message: Warning: The driver descriptor says the physical block size is 2048 bytes, but
Linux says it is 512 bytes.

Why it does not detect Windows 7?
Thanks for your help
