I've just recently bought a new 120GB ssd ( samsung 840). i've installed everything with a SATA 3gbs cable but i just found out that you can make the ssd "faster" by using the 6GBS SATA cable. The problem here is that when i switched cable from 3GBS to 6GBS and tried to start my computer and a black window pops up with " BOOTMGR is missing press ctrl+alt+del to restart... do i have a old motherboard or am i just doing it wrong?
