Hi guys, a few days ago I tried to install an SSD disk on my old laptop VAG-SR21M, the bios of this PC is restricted and does not let me activate ahci. When installing windows 7 I get an error when restarting. What kind of bios does this computer have? Can be modified to activate ahci? What steps should I follow?
