Because maybe you forgot to mount the disk.

mount -uw /

No. You don't want to run fsck from single user mode while the disk is mounted. This is just a problem that fsck can't fix.
To repair this, you'll need to use something like DiskWarrior. After that it may be necessary to reinstall the OS, depending on what, if anything, got corrupted due to the filesystem corruption.

Now that I think of it, you are right, Volumes will get unmounted if you repair the disk with Disk Utility.

The OP's problem might be different though, might have installed an incompatible OS for his Mac.

attempted to install OS Lion on my imac intel core i3 .

Did Apple ever put an i3 in an iMac? I thought the minimum was an i5

No, this is a problem that fsck can't fix as I said. Apple did make i3 iMacs, and they will run Mountain Lion but shipped with 10.6.x. Lion isn't the issue.

They did. It may have been an education only model, but I have several here at work.
