Hi.I had Ubuntu 13.04 running. There were some bugs and I was going to downgrade to 12.04, so, stupidly, I formatted the Ubuntu partition from Windows 8, which I had on dual boot. Now my PC will not start. On start, it says 'Selected boot image did not authenticate. Press enter to confirm'. Pressing enter shuts down the PC. I really need help. That is with legacy disabled. With legacy mode enabled, I get to a black screen that say 'error: no such partition.' It then pulls up a thing which says 'grub rescue>'. I have no idea how to get back from here. Does anyone have any ideas? I'm desparate.
Thanks,
Matthew Kaufer
