HP Recommended
Product: Probook 4540s
Operating System: Microsoft Windows 8.1 (64-bit)

Hello

 

I have a HP ProBook 4540s which currently has windows 8 installed.

 

I want to install windows 10 (full installation not upgrade).

 

I was having problems in removing the restore partition so I entered the BIOS using the Esc key then entering the BIOS settings and enabling legacy mode.

 

On saving the changes and rebooting the computer I used the Esc F9 key to display the boot options which displayed prior to my making any changes.  But this doesn't work.

 

The message that I get on the screen is

 

Boot Device Not Found

Please install an operating system on your hard disk

Hard Disk - (3F0)

F2 System Diagnostics

For more information, please visit:  www.hp.com\go\techcenter\startup

 

 

Instead, the system now automatically enters the HP PC Hardware Diagnostics UEFI page and no matter which keys I press both during boot and after the above screen apears I am unable to return the the boot menu.

 

I have trawled this forum and man others to try to find a solution with no success as all suggested solutions do not seem to work.

 

I would appreciate any help that you could suggest.

 

Thank you in advance for your assistance
