Apple Screen/Spinning wheel... Rebooting iMac 10.6

Was in the process of trying to clean up a mac, setting up new user account and such when the mac was shut down.

Now, only get white screen/grey apple start up screen with spinning wheel... after a period of time of not progressing the mac restarts on its on, repeats white screen/grey apple... repeats again... then shuts down.

Can't start up in safe boot mode (shift).

Option start up shows following volumes:
  1. Jeff B HD
  2. Windows
  3. Mac OS X Install DVD
But selecting the main volume "Jeff B HD" returns to white screen/grey apple/spinning reboot cycle.

Single user boot (command s), note "Root device is mounted read-only", run fsck and get "The volume Jeff B HD appears to be OK."

:/ root# df -hf returns:
Filesystem Size Used Avail Capacity Mounted on
root_device 460Gi 272Gi 188Gi 60% /

But no disk name?

Can boot from Mac OS X Install DVD but get error that "MAC OSX can't be installed on this machine".

Can get to Disk Utility from on the Install DVD and run 'repair' or 'verify' only, not permissions. Get volume OK message.

Can get terminal from Install DVD but seem to be a loss as to where to start or if that will even let me fix the unknown problem.

Any direction or help?

Start by resetting the SMC.

Then, try to install from the Mac OS X Install DVD. If it still isn't working after the SMC reset, tell us exactly, precisely, and in the greatest detail possible everything that it says on the face of the Install DVD that you are using, and exactly, precisely, and in the greatest detail possible what Mac you have.

Since the troubled Mac is a different model than the one that your Install DVD came from, you won't be able to use that DVD to boot the troubled Mac.
You need to get either the Install DVD that Mac came with, or get a retail version of the Install DVD.

Short of rattling my boss to find the correct disc...
Is there a way to productively run terminal from the never install DVD to clear possible permissions issue? (which is what I think is the root cause of this problem).

Woo Woo... Found the install DVD that came with the machine today and was able to boot from it!

Whaaa Whaaa... Though able to start "Repair Disk Permissions" from Disk Utility, right off get error stating "Error: The underlying task reported failure on exit." and stops with First Aid Failed.

Any words of wisdom?

Don't run "Repair Disk Permissions".
Instead run "Repair Disk"

But it seems that you previously were wanting to install a fresh copy of OS X - if that is so (and you have a backup of all files of interest on that Mac), then you should instead just erase the disk (to Mac OS Extended format) and then reinstall OS X.

Sorry, I shotgunned too much information in first post and not been clear..

Objective:
1. Take existing iMac with programs/settings/etc
2. Add new admin user with full permissions
3. Set up for new user (clean out junk/un-needed)

NOT clean wipe and restart from scratch. There is a 'mostly' intact backup of files that where on machine but my boss has mucked it up so it would be great deal of work to install/clean from that.

Had added new admin account, renamed hard drive, was in the process of letting machine apply updated persmissions. Left for the evening... Came in next morning and boss had shut machine down thinking I was done to move it.

State of machine at that point upon reboot was... White Apple/Spinning, looking for start up disk, cycles for time, Reboots, back to White Apple/Spinning, Repeats once or twice, Shuts down.

Found my way back here to you learned gentlemen after trying what I knew and coming up with no answers on my own to get back to functioning machine without full wipe.

Ran Disk Repair from Disk Utility from bootable OS X install (correct disc/came with machine) and it reports no issues.

Permissions will not run.

So can you boot from the hard disk now, or not?
(forget about permissions, just try to boot)
If you can't boot, it may be that the system files got corrupted somehow and in that case, you should do an OS X install (from the Install DVD) - I understand there is an option to keep all your user files. (In older OS X versions, this was called "archive & install" but now I think it may happen automatically - you get asked or something.)

But don't you have a backup of this Mac?
Assuming you do, you always have the option of just erase & install, then restore from backup.

NO GO on the machine booting on it's own steam.
White Apple/spinning, reboots, repeats this cycle 2-3 times, shuts down.

I have MOSTLY files backed up, but there are files/programs on the machine that are not (very unorganized boss who was working on this machine).

I'll attempt to do an archive/install of OS but was hoping there might be a terminal fix by resetting permissions first before I chance loosing programs/settings/etc.
