Can't reinstall Mac OS X Lion on my MacBook Air
Okay I'm going make a long story short I own a MacBook Air. I bought this MacBook Air yesterday off someone and they didn't take anything they gave me the password and everything but they took nothing off so I decided to reset the whole system to its factory settings so I followed the usual steps ( from a tutorial on YouTube )
1. Press alt+power button
2. Choose Utilities --> erase Macintosh HD
3. Reinstall the Mountain Lion OS X through internet.
after trying to install the OS X Lion, and entering my apple id an error message pops up, saying:
"This item is temporarily unavailable. Please try again later"
I don't know what to do, since I have tried redoing these steps on multiple occasions this day, and with two different networks(my network & apple stores wifi). I have to install the OS through internet (or if it is possible, by downloading the OS to an USB stick, and then installing through that).
Anyways, I started searching forms online to see if there was anything that I could do but all I can really find is make a bootable UBS drive but how can I do that if I only have 1 Mac and I don't know anyone else who owns a Mac. Every other computer system in my home is PC... I don't have any type of knowledge on macs so If anyone can help me in any type of way I would greatly appreciate it...
