Not starting, please help!

[Jacob1]

Today I turned on my computer to have it start loading normally and then go to a screen that says "Reboot and select proper Boot Device or insert book media in selected device and press a key". I looked  around and saw that it can be solved by going into my bios and messing with a setting however I cant get into my bios. When my computer first starts up it goes to a screen that says "Gateway" with their logo and then it just goes to this error message. I have tried pressing f1-12 while in both screens, esc, and del but nothing has worked. My computer was working just fine yesterday and I don't know what could have happened to cause this. Any help is greatly appreciated!

Probably a bad hdd. Check pressing the del key to open the bios.

I know you stated you pressed it while IN the screens, but have you mashed the keys while its initially loading? Also

I tried mashing the Del key from one I pressed the power button to where I get the error message, nothing has come up though. If it is a bad hhd how can I check without spare parts laying around?

As mentioned before just keep hitting DEL until something happens. It should get you into the BIOS. I see it's a pre-built all-in-one computer. I'm familiar with the fact that those computers commonly come preconfigured to skip the boot menu to increase boot speed with the expectancy that you never have a reason to go into the BIOS. When that is the case getting in there can be a pain but sometimes resetting CMOS is the only option...not sure how to get inside the unit though to do that.

So you want me to keep restating and pressing del until something happens or press it while on the error screen? And yeah, it is a pain to get open.

Update: I opened it up and plugged in another hhd and the same problem came up. Still can't get into bios. Is my computer rip?
