hard drive issue

hi, i just had a big issue with my main hard drive, it has dissapeared completely.
i look it up online and find out that my hard drive is about to fail, when i start my pc there is a screen that open and its called american megatrends and on forum it say that it is about to break, lucky me all me window driver are on ssd so i can use my pc still.

but my question is can i and should i unplug my main hard drive for now until i buy a new one so i can still use my pc?
