Computer showing error on startup, SMART failure?

Hey guys, firstly just wanted to say that this forum looks incredibly useful for everything wondows 7, after visiting for a while as a guest.
I have a problem..

Last night, i noticed i had low memory on my C drive. so I uninstalled a few programs - games mostly and needless addons - and then restarted. After restarting, the laptop got stuck at the bootup screen, at about 70%, then persisted to say "operating system not found" repeatedly.

This morning, after turning it on, it now gets past this screen, but says theres a "SMART failure predicted" on on my Hard drive. It also says ahard drive fail;ure is imminent. It does this for a few minutes, and then gets 'stuck' again at 70% at startup.

So.. is this a problem with my HDD? Everything points to this, but I'm not sure of my next step? Do i need to reinstall windows (problem, seeing as i don't have an installation disc)

Any help would be appreciated :/

Backup your DATA & replace the Hd Drive.

thanks for the quick reply. nothing boots up, it says to press various f buttons for setup, multi boot menu and system recovery but when i press these nothing happens. The laptop continually turns on, gets to 70%, turns itself off, then restarts.

I think its a problem with the HDD, seeing as it doesn't actually boot windows, just the manufacturer screen.
