Product: MacBook Air(early 2015) with OS X Yosemite.
The issue is, that I happen to have my Yosemite reinstalled, so I restarted my MacBook and at the sound of the chime(startup sound of Yosemite), I pressed ⌥ Opt+R and subsequently selected the Disk Utility. Once into that, I erased my whole Macintosh HD and then restarted the computer after which I was expecting the reinstall to be done automatically.
I am a novice in the Mac world.
Now once after the reinstall, I was forced into a screen with 4 options of reinstalling, Disk Utility, Time Machine and help from Apple.
I tried to reinstall, but due to a slow internet connection, I wasn't able to reinstall using Internet Recovery.
Now I created a bootable disk with "InstallESD.dmg" (using tansmac on windows) This copy of installed is the one downloaded from macworld torrents. It was after that I restarted the computer this time pressing only the ⌥ Opt key and then all I had was this black screen with a box that asked me for the network I had.
I selected mine in a hope it might work with my USB but it just shows an Internet Recovery option with a globe which I cannot afford due to my slow internet connection. Is there any specific key to select the bootable image because it isn't appearing there?
