Hey guys, today I have done one of the stupidest things in my entire life. I was screwing around with my partitions on my boot-camped windows partition, trying to add more space to it, (I still couldn't figure out how to do this, any tips?) and I appear to have accidentally wiped my ENTIRE Macintosh HD. Don't ask me how I didn't realise what I was doing, though I did think that maybe the process was taking a while... heh... eh. Fortunately, I have made a time capsule backup very recently, and so I can restore from that backup, if only I knew how to reinstall Mac OSX. The issue is that I HAD Lion installed, and I downloaded THAT from the Mac App Store, so no CD... And the funny thing is, that in 'Computer', there are TWO HDD's: BOOTCAMP, AND Macintosh HD - it appears to still be there, but when I hold alt/option when booting, only the Windows partition appears, and in all of the Windows partition editors, what USED to be Macintosh HD just appears as empty space. I have included some screenshots below, to show this. Has anybody got some helpful instructions on recovering and/or reinstalling my OSX partition?
This is what shows up in the partition editor.
And THIS is what shows up in 'Computer'.
