The system does not see a discrete graphics card?

Question

Video cards

the system does not see a discrete video card
, the thing is that a
friend asked me to change Windows, stupid laptop Asus a52j
It was 7-32 roses.
I also started installing 7 ku 32zh roses, but of a different assembly (it works without problems on a stationary PC) , at
first everything seemed to be going fine, the first step was "collecting information", I did everything, formatted it, everything was as it should, the second step - everything is installed by itself, then the computer rebooted, and then the next process "the installer checks the video performance"
restarted, everything started but only on the integrated video, the system does not see the "radeon HD6370M" discrete device in the device manager, AIDA sees it, there is no way to switch in the BIOS, the driver installed -does not help, but the profile flew off, entered with a temporary one,
Help experts????
