    Operating System Not Found


    Hi, my Acer Aspire One was upgraded to Windows 10. Eventually, I ran into some issues with the start menu not popping up, so I decided to run a clean reset of Windows 10. The reset failed, so I turned off the notebook. When I turned it back on, the message "An operating system wasn't found. Try disconnecting any drives that don't contain an operating system. Press Ctrl+Alt+Del to restart," popped up. My first option was to try to use either f2 or f12 to see if there was some way to get around the issue, but then I remembered that, recently, my notebook had stopped responding to those commands. I do have a USB Logitech K120 keyboard hooked up to it (since the original keyboard messed up,) but it had been working fine for those commands and such up until now.

    Today, I downloaded Win 10 using the Media Creation Tool in an attempt to create a bootable USB drive. I plugged that in, yet it doesn't seem to recognize it at all. The same message pops up as before. My acer doesn't have a CD-ROM or anything of the sort, so the USB appears to be my only hope. Is there anything that I can do? I'm hoping there's a way I can force the notebook to recognize the USB, or at least boot into the f2 or f12 commands to see if I can use them in any way. Thank you.

    :)

    Any chance the original keyboard F12 key works?

    Unfortunately, the original key won't work. That keyboard is broken. The odd thing is that it used to work for the USB keyboard replacement, but, for some reason, now a perfect storm of coincidences has clustered up into a big problem. The USB does turn on and such, and the notebook does appear to recognize that I'm hitting keys as well, but for some reason it just won't boot off the USB or at least enter an "f"option.
