The loading of the installation from a Yosemite USB installer drive is interrupted by a blank screen about ⅓ into the progress bar. The same USB drive works on another (older) MacBook Pro.
The MacBook (8,2 which should be early 2011 but on the back it says 2010) is equipped with a blank SSD drive.
The following boot options had some effect:
-
alt (boot select) allows me to select the USB drive.
-
cmd-alt-P-R (NVRAM reset) had some effect (screen is brighter now), but did not solve the problem.
-
alt-R (internet recovery) loaded all-right, went into the phase where there is the Apple logo and the spinning lines below, and then went blank.
-
alt-D (internet HW test) is executing, but does not find anything but the disconnected battery (battery is dead).
following boot options do not have an effect:
- cmd-V (verbose)
- cmd-L (log)
- D (hardware test) – no surprise since nothing is installed on the SSD
Any clues as to how I can get the machine working?

I had the same problem. I had to format the ssd in another Mac before I could move on.
