I am a little uncertain about exactly what is happening. If the laptop came with Windows 7 pre-installed, could it boot into Windows 7 at that point?
You may want to do a factory restore, the procedure for which should be in your owner's manual, or online. But whatever key combination might be available, may be specific to that model. If you can use the F8 key during boot to get to the Repair your computer option, you could try a startup repair.
If you have attached any devices, like external drives to the laptop, you may want to unplug them.
