After Disk Utility couldn't repair my hard drive, and I was told to erase and reformat, I attempted to reinstall Mountain Lion but I keep getting this message saying "This disk is locked".
Any help would be greatly appreciated, thanks.
macbook, Mac OS X (10.7.1)
SOLUTION: Guys don't waste your time. I had this exact problem but I tried using command + alt + r during boot up. Hold it till you see the globe pop up and let it do its thing and that should fix the problem (at least it did for me). Then you can install without problems. Good luck!
If didnt work buy an external hard disk and connect it to your mac and go to disk utilities and go to ur old hard drive then go to restore ,if the sorce is your hard disk name so thats ok usually its macintosh hd and in the other side destination grab the new hard disk, the new hard disk is gonna erase and copy the old hard disk so you are gonna have a back up ,when it finishes go to ur old drive theb click erase it will work ,you must put it on macOS (journaled) or the first option then just do the same on the first and it will work.
Good luck
Hi Linc Davis,
You say there are ways to back up a computer that isn't fully functional. Help! The only way I can get into my computer is via command>r. I assume I need to back up my computer before I do a reinstall. How do I do that. I tried disk utility repair and got 'Invalid node structure', 'Disk full error' and 'Error: disk Utility can't repair this disk. Back up as many of your files as possible, reformat the disk, and restore your backed up files'. I have a Seagate external hard drive. I cannot get to my desktop at all. Can't reinstall Lion because the HD is locked, although I think I need to back up first if possible. I have tried double clicking the HD in the utilities window and nothing happens. FYI, when starting the computer with no commands I get the apple, the progression bar and then it shuts down. Thanks in advance!
That is what my iMac is doing!!
