So, recently i had this client with a Samsung NP530U3B with a HDD with 40+ bad sectors (with only 10% of the HDD test!) and i suggested an upgrade to a SSD 240GB, told the client the pros of that kind of upgrade, and he accepted. Little did i know the problem i was about to have... In my company, we use USB stick with windows ISO's to install on the clients computers, and sometimes we use DVD's, but in this particular situation, because it doesn't have a DVD drive i used our USB to install W7 in this machine and everything was going fine, i selected the SSD as the destination for the Windows installation, and i installed W7 but when i rebboted for the first time to continue the instalation and configuration, it didn't boot! I saw de Samsung logo and the nothing.... i entered in the BIOS and everything semmed to be alright, but still, i tried a lot of different configurations just to be confronted with the same problem... changed the SSD and nothing, i even tried with an HDD and still nothing, so after spending some time googling i found the answer... i just needed to install windows using an external DVD drive and a copy of windows 7 and it worked just fine, after that i upgraded to Windows 10 and it works just fine 
Of course i tried other solutions, found them in another foruns, if it's ok i'll post them here
