Not starting.

Hello,

I was using my laptop Samsung Laptop - 300E4Z-A06 and the battery got low. I continued to use it, then suddenly the system started closing so I closed the shutter and went to sleep. When I opened it the next morning, it asked me to start the windows normally. I selected and waited for my system to open. Then the Samsung logo appears and then comes a black screen with a white blinking underscore, after that a black screen and again the Samsung logo appears. It keeps on repeating. All this happens in seconds. It is very quick. I tried to press f2 and reseted all the settings to default. It didn't work. I tried pressing f4 but it was of no use. I tried to remove the battery and hold down the power button and then plug in the charger and press the power button and then insert the battery, bbut that didn't work too. I don't have a recovery disk also. But when I keep pressing the escape key then a some options appears, like Windows 7/vista/server (pointer) and many more. I used all of them but the same problem appears. That laptop is my only source of income, please help I would be every grateful to you.
