Solutions for existing HDD Bad Sector

I have an HP G60 laptop which I purchased on 2009. I forgot when it happened but the laptop suddenly stopped when I used it.. I tried to restart it, but a black screen appears with the words "Disk failure is imminent".
I browsed and tried Googling it. There were suggestions from forums that provided solutions to try HDD Regenerator. I tried these suggestions: I burn ISO to DVD and I tried to boot , then I scanned, it was more than these two bad sectors. I tried to repair it, but the failure continues.
I have no budget to buy a new laptop or buy a new HDD.
Anyone has a solution? Thank you in advance.
