os install on imac 27" late 2009
why wont it boot up after fresh install after completed it does a restart and the screen doesnt load up past 3/4 of the loading ?
Please read Writing an effective Apple Support Question and then re-write your question. All we know at this point is you have a late 2009 27" iMac and it will not boot. I suspect the HD has died, if this is the case I would NOT recommend spending any money on it, you got your monies worth out of it and it's time to replace the computer. However you can try a Safe Mode restart or restarting in the Recovery Partition and running First Aid several times on the HD, if errors appear that just confirms my hunch of the HD failing.
