Mac Mini 4gb memory 320 gb HD Snow leopard was installed and the problem commenced whilst carry out mountain lion upgrade
repair disk is not available... only verify disk or verify disk permissions. repair disk is greyed out
First we can boot into Safe Mode and see if it works or not. Turn off your Mac. Turn it back on and immediately hold down Shift key on your Keyboard. Keep it held down (max of 5 minutes) and it will boot into Safe Mode
If that didn't work, then we can try Disk Utility.
Turn your Mac off. Turn it back on and this time hold down the Command (Apple) key and the S keys at the same time. This will boot your Mac into Single User Mode. Then type the following command... /sbin/fsck -fy (note the space between fsck and -fy) If you can't run /sbin/fsck -fy then type only fsk - fy
Or type fsck_hfs -fy
Hit return and the disk utility should run and let it finish. When it finishes and there is no error, then type reboot and hit return. Let the Mac boot up.
Please let me know how it goes.
Hi ran verify disk permissions which brought up lots of error 5 messages, then ran verify disk, then ran repair disk and got message: error disk utility cannot repair this disk. Then disk utility window opened and message said: reformat disk
Shall I follow your last instructions re booting up in safe mode or should I skip that and boot into single user mode and type in the commands you gave me?
Sorry Ashik, but after no response for 7.5hrs I decided to erase and do a clean reinstall from my original Snow Leopard disk. I did lose all my data as I knew I would.
Thank you for your initial help, which unfortunately was unable to solve the problem
How do I do that? If you can guarantee I will be refunded it's not a problem, I know you tried. Thanks.
OK, I will do that. Thanks for your time.
