Hi there I am hoping someone can help!

I have a Macbook Air (1.6Ghz Intel Core i5, 2 GB 1333Mhz DDR3 mid 2011).

I updated it to Yosemite and for a time it ran perfectly with no issues. After a few weeks though I experience random crashes and have looked around online and found that it might be best to do a factory reset and roll it back to Mavericks. However when trying to do this the reinstall has failed every time for unknown reasons.

As a last ditch before taking to a shop I attempted to use a 32GB USB drive as I figured there may be an issue with the hard drive on the laptop. I have now successfully managed to get the laptop up and running thanks to Internet Recovery and I am running Mac OS X Lion 10.7.5 (11G63).

I have done some hard drive tests using Disk Utility and it all comes back green.

I now need to get off the USB drive and back on the Hard Drive. Please can someone advise??

I also want to get back onto Mavericks and not Yosemite ideally

Many thanks in advance
