Whenever I start up my Dell XPS 15 I get the error "Internal hard disk drive not found..."
I checked the BIOS and it shows the hard drive is there and also ran the Dell Startup thing that checks the different components and got no errors.
What do I do next?
What is the exact system model? What is the current OS on the machine? When did the issue start? Does the system have only one HDD or is there an msata drive? Does it boot into windows at any point at all or do you only see the message after the Dell logo and nothing after it? Was the system dropped? Was there any liquid spillage on the machine?
Try resetting BIOS defaults and check - press f2 key on startup to enter BIOS - press f9 to load defaults and f10 to save and exit. Restart and check.
Try reseating the HDD and check - http://dell.to/1n3X2po - enter the service tag and download the service manual.
If the system is under warranty, write me a private conversation with the service tag and your contact details. If there is no warranty, then we can help with a paid service call if required.
Keep us updated.
