Problem new ssd drive

Hi

I've put my new ssd in one laptop and changed hdd to ssd in another one.

And after installation,  in my used ssd that I switched to my 2nd laptop (e6530 to e6420) this ssd has linux and once switched on 6420, Error : selected boot device failed.

I tried UEFI and legacy..

Nothing. 

that one is detected by the bios but no boot,  

The bios detects my old drive in the 6420 but on bios it says : 480gb hhd and my drive is ssd....
