I have had a minor problem over the past couple of years, and just wanted to know if anyone has any thoughts how I could solve it. Every few months, when I start my computer I get a blue screen that tells me I have an error and that I need to run a chkdsk or that some new software might have a virus (I haven't gotten this in a while so I don't remember the exact message). What seems to be the problem, is that for whatever reason, every once in a while my computer seems to boot up using another drive. So I have to press F8 when starting up, and select the correct drive. And then I have to re-start and go into options, and select the correct drive as the first option. After that it works perfectly fine, except after another few months it does the same thing. I always shut down my computer the correct way, so I don't know what causes this, nor how to permanently fix it. I don't know if this is an issue, but there is also a message when starting up that reads "BIOS not installed". Not sure if its related. This isn't a big deal, as its more an annoyance than a real problem, but I'd certainly like to fix it if I can. Thanks!
