Issue with SSD drive

Hi avasters,
My laptop has a SSD installed windows 8.1 and a harddrive that used as a storage.then when I install AIS on the SSD,I must wait at least 5~10 mins before it log in to the system.
Then I uninstall the AIS,and reinstall it on the harddrive,it works well.
I dont konw what’s wrong with my system,so I reinstall the system,and install AIS on the SSD,this issue appears again.

I think it a program bug,and it must be announced to you.
