Is there an alternative to downloading Lion from the net? 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 &#8984;+Deleted everything. Needless to say, my Mac does not boot up now.

After searching, I found that &#8984;+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?
Sorry but I don't know of any other way to reinstall your lost data.

If you do want to download before installing, borrow someone else's Mac to


Download Lion from the Mac App Store. The installer should show up in your Applications folder.
Right-click on the installer and hit "Show Package Contents". Navigate to Contents > SharedSupport and look for a file called "InstallESD.dmg".
Open up Disk Utility and drag the DMG file into the left-hand sidebar. If you're burning it to a DVD, insert your DVD, select the disk image in the sidebar, and hit the "Burn" button. Skip down to the last step to use it.
If you want to burn Lion to a USB flash drive:


plug it in and click on it in the left-hand sidebar in Disk Utility.
Go to the Partition tab and select "1 Partition" from the dropdown menu. Choose "Mac OS Extended (Journaled) on the left.
Hit the Options button under the partition table and choose "GUID Partition Table". You'll need this to make the drive bootable on a Mac. Hit the Apply button when you're done to format your drive (note: it will erase everything on the drive).
Click on the "Restore" tab, choose the InstallESD.dmg file as the source and your flash drive as the destination. Hit the Apply button and it will create your bootable USB drive.

Connect your MBAir DVD drive and boot into OS X and hold the option key when you hear the startup chime. You can boot into your DVD or flash drive from there.
