Installing El Capiton on an old Mac Book Pro today, I received the error:

Quit the installer to restart your computer and try again.
I checked Apple’s support Matrix (it is a very old macbook pro) at https://support.apple.com/kb/SP728?locale=en_GB and it was listed as supported.

Install Os X 10.11
Oct 02, 2015 Many thanks for your help, I've solved the problem 🙂 But I did reformat Macintosh HD, not the internal drive above it. There was no problem with the internal drive, verify disk and repair disk worked, but none of them were selectable for Macintosh HD and El Capitan couldn't be installed on it. During the installation of OS X El Capitan on my Mac Book Pro, the install fails and I am left with 'OS X Could not be installed on your computer File System verify or repair failed. Quit the installer to restart your computer and try again.' No matter how many restarts I do it does not install. Also repair does not work in disk utility.
