I have a 13 inch Macbook Air 2011. A couple of days back, I was deleting some files and I landed in the Macintosh HD folder (root) and from there I ⌘+Deleted everything. Needless to say, my Mac does not boot up now.
After searching, I found that ⌘+R goes into recovery mode. Now, I'm on this screen (screenshot not mine):
and my Mac says 23 hours remaining. This is my 4th attempt at re-installation and I just can not get it to finish quickly. Sometimes I lose my net connection in between and the whole process starts over again. I have spent at least 72-90 hours reinstalling the whole thing 3 times, but it just doesn't finish. I'm on a 2 Mbps connection.
Is there an alternative to downloading OS X Lion from the net?
EDIT: I don't know anyone who has a Mac, and the Mac store is in another city. If I somehow do get the "Mac OS X Install ESD.dmg" from someone, is it possible to burn this into a bootable USB using Windows 7?
