Alright so I've definitely done something to my Mac. This morning it decided it wouldn't start. I tried to talk to it, tell it I love it, nudge it a little, nothing. Eventually a gray screen pops up with the apple logo on it and it won't budge, so then I began googling. First I tried to safe boot, which it would do, get half way through and suddenly shut down. Then I tried that FSCK thing, but again the black screen would show up, text would start running then it would freeze and shut down. Then I reset the PRAM thingy, which also didn't have an effect. I then went to disk utility and tried to verify my MACINTOSH HD disk and it showed up errors and promoted me to fix these. I tried repairing only to be greeting with another error message saying I need to reformat it. I left that, went back to the repair screen and tried reinstalling OSX (maverick). Error messages kept popping up and I soon realized the dye and time was scrambled. I reset this in the terminal (manually) and tried again. This time it got all the way to where I could choose between two disks, both of which were locked. I then went BACK to disk utility, and googled how to reformat the disk. I was told to select it and erase it, which I did. But I don't think I should of... Because now it's gone. Thereafter I successful safe booted it but it took me back to the recovery screen. I then did the FSCK thing again which worked this time, but took me to the recovery screen again. Then I reset the PRAM thing and still the same. I tried to reinstall OSX but now all it gives me as a disk option is the recovery disk which is also locked. I tried creating a partition to get my MAC HD DRIVE back but it just says an error occurred and it was unable to create the partition. Other info: My work is not backed up (my error, I accept il probably lose it) I don't have my disk anymore Help anybody???
