I'm now having major problems with my iMac. I had a massive software failure running Mavericks, it damamged the OS and I lost the recovery partition, I then wiped the hard drive clean and tried to upgrade to Yosemite, it failed numerous times (unable to verify etc etc)
I then tried to create bootable Yosemite...also failed with installing one of the essential packages.
I am now running the iMac off a cloned version of my damaged Mavericks OS and the recovery partition says it's Yosemite and doesnt work.
I have also tried to reinstall from Lion CD, again not working.
Also the Internet Recovery does not work.
I seem to be in a loop of trouble....how do I go about just doing a clean install of anything?
