Some Windows users reported that when they boot up their HP computer, they see the error message No boot disk detected or the disk has failed.

What causes the No boot disk detected error?

This error occurs because, during the process of booting up a computer, the system checks the HDD for boot information and other Operating System information so as to utilize the information to boot up the system.

However, if the HP computer is unable to retrieve any not boot information or Operating System details on the HDD, the error message is displayed on the screen. Another variation of the error message that may appear is the requested system device cannot be found.

The reason for the boot information retrieval failure is largely connected to the HP computer/laptop which includes:

So I put in an old windows 10 iso disc that I made and it acted like it was going to start up but then it went to this screen

Boot device is not found

Please install an operating system on your hard drive

Hard Drive — Error (3F0)

F2     System Diagnostics

and then tells me to go to a hp tech center  start up site  (my computer is a HP Pavilion 500-217c)

I have no idea what to try next, except to take it to a computer place and see if they can retrieve my files and order restoration discs for my computer, because of course I never burned them off my computer
