|Well, there are several directions you can go with this.. |
Crazy question time:
Do you have valuable data on that hard drive (you didn't back up somewhere else)?
What happened before this, do you remember? Install something new? power outage? dropped? etc.
If it was me, before putting in the disk i would see if I can make it POST..
Turn it off and remove the power.
Remove the Hard drive from the laptop
Plug in the power and boot it up.
It should boot with an error, something like:
No boot device found (should be different than you see now)
On a side note: Windows 7 does have a "repair" option but personally i make it may LAST resort.
Something in the BIOS could have gone squearly on ya, if you've never altered your BIOS then it wouldn't hurt to go in there and reset to default. If you don't know how then let say so and will help describe the steps.
