startup menu mac book pro not functioning
when i press the power button and hold the option key just the "choose network" become visible. No sign of hard disk and no sign of bootable usb. I tried internet recovery and while starting to install the time between -2.123.834.322 and 32 min shows up and "cannot download the additional component needed to install mac os x" appears. Tried opt + cmd + p + r and nothing changed. In disk utility menu in the internet recovery, hard and usb is there but in the startup menu nothing is there. Is this a hardware problem or software?
mac book pro 8,1
base os Lion
hard formatted and doesn't have recovery partition
