I have a Macbook Pro 2010 13 inches, and I had Yosemite installed. I decided to download El Capitan from the Apple Store and then proceeded to the installation, which was gonna take 30 minutes. My charger or my charger cord has been showing weird issues: sometimes when plugged, if I touch the cord, even gently, my mac shuts down. And that's what happened in the middle of the installation. When I turned it on again it gave me the option to continue the installation, which was at 24 minutes. However, after about 5 minutes, it tells me it cannot go on with the install. I tried everything I can on Disk Utility but nothing works. I can't continue the installation and I can't access my HD, even though on Utility the data is still all there, although I know that the HD might have been corrupted permanently. Any advice? Oh and I do not have the Yosemite or El Capitan dvd.
