Hi, can anyone out there help, please? I have an HP Envy Touchsmart 15 Notebook, which my two teenage children use, primarily for games, YouTube etc. For no apparent reason, its now showing a black screen with the following messages:
Boot Device Not Found
Please install an operating system on your hard disk.
Hard disk (3FO)
F2 System diagnostics
It should be still under guarantee but I'm hopeful there may be a simple fix that will avoid having to re-install software etc. NB Recently upgraded to Windows 10.
In my experience, this usuallyhappens if one of three things have happened ...
- there has been some corruption of the hard drive - either by physical damage or malware activity;
- the hard drive has been reformatted;
- the hard drive has become dislodged from its mountings and the connectoion between the hard drive and motherboard has been interrupted.
There are more causes, but try checling these first.
To check the drive is still connected, try following the instructions on page 44 of this site:
Make sure you power down and remove the battery and power cord first.
To check if the hard drive has been formatted you will beed a third party cd like a Linux live cd (downloadable fron the internet) and see if any files exist on the hard drive. Linux is way different to windows so it might take some time to become accustomed to it. Alternatively try "Parted Magic" live cd/dvd. This also has a file explorer function.
You could skip the above check if you have an installation disk for your machine. The machine should have come with one, or you would have needed to burn it from the (usually hidden) partition when it was working. If you boot from that cd then you could also try to repair the installation (follow the instructions that appear when it boots from the cd/dvd)
The virus option would require you to remove the hard drive and put it into another working machine as a secondary drive and check for viruses using the host machine. This is a rare occurrence - virusses usually dont destroy the operating system to this extent, but it is a possibility.
Please let me know how you get on.
I really appreciate thank you messages as a payment for solving issues :o)
Thanks for your prompt reply. Laptop doesn't come with an installation CD, probably because there isn't a CD drive! I've managed, using the F keys, to get to the BIOS menu and system config and there's no visible evidence that a HDD even exists and I can't hear it, so I suspect the drive has died. I've learned that the machine came with a three-yr warranty, so the easiest option may be to take it back to the vendor (an upmarket UK department store). I suspect they'll swap it for a brand new model, rather than send it to HP for repair. If so, I get a brand new machine and just have to re-load the anti-virus and games software etc. there are no document files to worry about. That will save me a lot of grief and this is the holiday season, FFS!
