My macbook is making me choose 'untitled' hard drive on start-up

[Dawn25]

Hi,

I'm relatively new to Mac, only had mine for 6 months. Everything's going well and it's working fine, however, on 3 occasions in the last 2 months, when I've turned it on, before it goes to the white screen with the circling loading icon, it's made me click on the 'untitled' icon of my hard drive (at least I think that's what it is). The computer doesn't seem to run slower or encounter any other problems following this, I'm just a bit concerned as there doesn't seem to be any reason for it. I don't have Windows as an optional operating system etc....

Hope someone can shed some light....?

Thanks,
Dawn

Check System Preferences > Startup Disk ... make sure you Mac's HDD is selected.
