Help!! Alienware 14 keeps restarting over and over again

H!!

After I recently updated my alienware 14 to windows 10, it has been restarting over and over again. I cannot log into my laptop.

I tried to access safe mode by pressing shift+f8 and only f8 on different occasions, but unable to.

I can only access bios by pressing f2.

Can anyone please help me solve this problem asap as I urgently need my laptop to do school work and projects.

Thanks a lot.
