Computer was working fine and shut it down for the night. Tried to start it in the morning and it won't boot. Hp Blue screen apears with 4 options- then changes to black screen and tells me to enter the device media and press any key to reboot the computer.. I have a lot of information in this computer that I need access to. Any ideas on what I can do to get my computer to boot. I am unable to access the System Recovery or the Diagnostics. I can enter set up and boot options. The only boot option availabe is from the dvd. I live in an isolated area and do not have a computer repair person available. Is there any things I can try that might resolve this issue?
