Install Failed - Disk is damaged

I have just gone through the update procedure to make sure latest version installed on my MacBook Pro, and installed latest update. Went to App store and purchased Lion, downloaded and starts to install, but fails saying;

"Install failed. Mac OS x could not be installed on your computer. Mac OS x Lion couldn't be installed, because the disk Macintosh HD is damaged and can't be repaired. Click restart to restart your computer and try installing again"

I have clicked restart and keep getting the same error. All was working fine before I attempted the upgrade.

How do I resolve this please?? I now have an expensive hunk of useless alumimium..........................

Cheers,

Jim

I am no tech geek, but I tried to repair my disk. It looks like Lion created all kinds of conflicts in the Library. I repaired it, tried to install Lion again, and all the conflicts came back.

Sounds like you are in the same position I was in, check out my post on page 3, you need to run fsck_hfs command in terminal while booted off your snow leopard disk.

What exactly did you delete? I have access to my mac drive from my bootcamp drive, and I'm willing to try this.

Zap the PRAM. Restart the computer, then hold Opt-Com-P-R until the computer chimes again. The Lion installer should appear thereafter.

Thanks, Erik. Using your suggestion, I was able to boot from my Snow Leopard partition. Now I can wait until I return home to worry about installing Lion.

I spoke with an Apple Tech tonight when I had this problem who took me into the disk utilities to repation the McIntosh HD volume, after that Lion OsX is updating perfectly 🙂
