I tried upgrading to lion through the app store, it didn't work and asked me to restart. Now all I get it a blinking apple logo, a blinking error logo and a blinking hard drive logo with a question Mark on it. I booted from a CD and I'm currently in disk utility. It recognises the disk but the macintosh HD part is greyed out and it cannot repair it. It shows an error "keys out of order" when repairing.
Nothing was wrong before hand so i have no idea whats happening and really need help fast.
Luckily I've backed up all photos and important documents which I need although i would like to have everything intact.
So I beg of you guys to help me! Thanks in advance.
Restart and hold down Command+R and see if the Lion recovery/utilities shows up. If so, you can try to re-install it through that. Lion creates a small partition just for recovery in instances like this.
"Accessing recovery mode
You can access recovery mode only when your Mac starts up, although there are two ways to do so:
The easier way On newer Macs, you can access recovery mode by simply restarting or starting up the Mac and immediately holding down Command+R. Keep holding these keys until you see the Apple logo on the screen. After a few seconds, you'll see a window with Mac OS X Utilities in large text across the top. If this procedure doesn't work for you, try the second method.
The alternate way On any Mac, you can access recovery mode using OS X's Startup Manager:
1.Restart or start up your Mac and immediately hold down the Option key; keep holding Option until the Startup Manager--a gray screen showing all connected, bootable volumes--appears. One of the volumes will be called Recovery HD.
2. If you'll want to connect to your local network (for example, to access backups on a Time Capsule) or the Internet in recovery mode (see "Using recovery mode," below), you can use the pop-up menu at the bottom of the screen to choose a local Wi-Fi network; provide the network's password when prompted. (If you prefer, you can wait until you're booted into recovery mode to choose a network.)
3. Select Recovery HD and then click the upward-pointing arrow below it to boot from Recovery HD. After a brief delay, you'll see the new Mac OS X Utilities screen."
