Laptop does not startup (not even safemode)

Hello,

I was using my computer this morning, and i got a popup no just any but a antivirus 2010 popup. Not a thing to worry about normally. I had it before so knew what to do. I wanted to start malwarebytes. Did not start. so i raised my eyebrows and tried a second and third time. Without good result. so i start looking on the internet, found differen sites that tell me to download it again and install it in safemode so after disabeling the antivirus software.

all i wanted was to restart, but untill now 3 hours later i did not see windows again. its stuck.
i tried: safemode
safe mode with network
safe mode with command
last knows startup that works
normal startup
or with other word everything that was posible.

you have any good ideas
btw there is no space on the disc to put an wxtra windows on it (dual boot)
thanks
