Run the command: fsck_hfs -rf /dev/disk0s2 (Your partition name might be different.).

Click on 'Macintosh HD' and then 'Unmount'.

Boot from Snow Leopard DVD by holding down Alt after the chimes and selecting the DVD option.

Here's what worked for me, courtesy of a very helpful forum user by the name of bart: I had exactly the same situation - allegedly damaged hard disk with invalid node structure, on a bootcamp partitioned disk withh endless looping of installs and no route back to Snow Leopard.

Install Failed - Disk is damaged on Apple Discussions site.

I don't mind wiping everything (including Bootcamp), but I rather that be a last resort. I do have my files backed up (not in Time Machine, but manually on an external USB drive). I think many others are having this issue as well. Every restart leads back into the Lion install, which results in these errors. I am unable to get back into Snow Leopard. I don't know if that has anything to do with why I'm getting these error messages or not, or if that's why it thinks the hard drive is damaged.

I'm also running Bootcamp, with Windows 7 installed in it's own partition. Back up as many of your files as possible, reformat the disk, and restore your backed up files. Click Repair Disk.Īfter clicking Repair Disk, I got this error message:ĭisk Utility stopped repairing 'Macintosh HD'ĭisk Utility can't repair this disk. The volume Macintosh HD could not be verified completely.Įrror: This disk needs to be repaired. I clicked on Verify Disk, and got this error message after it ran: I put the disc in, booted it, and clicked through past the language selection, but made sure to wait for the top menu bar to appear to get to Disk Utility. I read somewhere that I should put in the original install DVD, and run the Disk Utility to try to verify and repair.

Mac OS X couldn't be installed, because the disk Macintosh HD is damaged and can't be repaired. Mac OS X could not be installed on your computer When it rebooted, it began to install Lion, and when it was at the 33 minute mark, it failed. When I returned, I resumed it again, and after download completion, began to install it. During the download, it somehow stopped while I was away from the keyboard. I am running the latest Snow Leopard on my 2010 15' Macbook Pro. I downloaded the new OS X Lion from the App store.
