My laptop wont start after reinstalling norton 360

Hi,

recently my norton 360 on my home laptop was about to expire so i bought a new copy and installed it on my laptop.. after restarting my computer doesn't seem to want to start.

 

every time i turn it on, it runs the norton system recovery? but only when the cd is in the driver..

if the cd isn't in the drive it just displays "windows system recovery" but does nothing and resets every 25 seconds or so...

 

any ideas on what is going on?

 

there were no viruses on the laptop and this has only started happening after i installed norton 360!
