Windows 7: Windows refuses to show Boot Menu/Start from Microsoft Logo

Hello.

A few days ago my laptop with Windows 7 stopped somehow wanting to get past by the Microsoft Logo (where the 3D balls in light come up), it stays like that, it doesn't freeze though.
The animation just loops forever.
I tried accessing the boot menu and the repairs, but it didn't work.

However, I handed it to my dad since he has a bit of more experience than me and made it worse, so now the first text to appear where it even says "Click here to enter boot menu" doesn't really appear.
The weirdest is, it happens to all the internal disks I've put there (3 of them)!!

Now even if I try to load any safe mode, the computer just goes BSOD for a second and turns off very fast.



I wouldn't like to lose my stuff as it's my work on the original disk, my college work, my bank account information and some other important things, it's extremly important to me.

Sure I could just buy those USB boxes where I can place my internal disk onto it then buy a new disk for the computer but - what if it happens again?
The Boot Menu won't exist, so it's like the computer itself was garbage for me...

What can I do??

PS : I've learned my lesson next time.
No Just Cause 2 or any other game via torrent.

Thanks.
