should i change the boot priority in the bios so its the sdd first then dvd hdd??
for your first start up and installation of windows.
DVD drive first.
SSD second.
then once its all installed and running, go back into the bios and make the SSD first and disable all other boot devices, this will speed up the boot up time.
and once windows is complete change it to sdd dvd hdd??
And, the AHCI mode should have been enabled before you did the install.
TRIM support for the SSD may not be working otherwise I think.
