Hi there, I've searched for a while for this answer, but I keep getting results about upgrading from Snow Leopard. So here is my problem: I bought a new iMac from Apple recently, it shipped with Lion and came with no install DVDs or anything like that. I'm wanting to wipe the HDD so I can get rid of all the rubbish I've installed over the last couple of months, now I know exactly what software I'll be using. How can I do this? There's talk about buying a USB drive from Apple, or downloading Lion from the App Store and making my own, but these methods sound more annoying/complicated than the standard install DVDs. Could someone walk me through the process? Hoping it can be done soon/cheap. Thanks.
