Desktop Envy 750-287c.  "Boot device not found - please install an operating system on your hard disk. Hard Disk 3F0"   I use F10 to go into BIOS settings. In Boot Order, both UEFI and Legacy are disabled. I enable UEFI, Save and restart. Same error. F10 into BIOS again, UEFI and Legacy both disabled! BIOS is not remembering the change. Battery? No - I put in new CR2032.  Date/Time is maintained ok. Tried enabling Legacy - same error, the change is not remembered. The error panel offers F2 into Diagnostics. Hard disk - an SSD - checks out ok. Corrupted BIOS? It is A0.16 for system board 2B47. Firmware diagnostics has option to flash an update. I download latest from HP, but it is a program to be run from Windows! How do I get the BIOS flash files that the firmware updater is looking for? Since I cannot set a Boot order, I cannot boot into any recovery media.  Any ideas on what the problem really is? Motherboard failure?
