cloning hard drive but no boot

[dontaskmetodance]

Hello. I'm working on a Dell Latitude 64000 with windows 7 ultimate 64 bits

I wanted to clone my system drive from the actual HDD to a new SSD.
I did it, i can see both drives have the exact same 2 partitions. One is about 100mo, the other is about 100go.

However, the computer doesn't boot when i use only the ssd.

Any idea if i missed something ? maybe you need more information to help me ?

thank you

What was preventing you from reinstalling the OS onto the SSD from scratch, after creating a bootable installer for the OS?
