I have a compaq laptop and unfortunately I cannot start it up due to it shows "BOOT DEVICE NOT FOUND" (3FO) and I dont know why and I dont know what it is. I need help with this. What am I suppose to do?
Hello... it is looking for your Bootable Operating system, to start up. typically it's your hardrive it is looking for... Something has changed that it is not finding your Operating System on your Hardrive... Could be a setting in your BIO's, a connection problem, or a failure of your hardrive.
Hello... download the manual for it, and learn how to get into the BIO's... do you have a DISK/CD/DVD/USB drive plugged into it while starting? Remove it... Ask a computer savy friend to help you, look at it?... take it to a local computer repair shop.
