Product: HP Pavilion x360 Convertible Laptop PC 14-dh0021la
Operating System: Microsoft Windows 10 (64-bit)

Notebook had f.07 bios and booted in legacy mode. After latest f.20 bios update it doesn't boot stating that an OS must be installed. Switched to UEFI and back to Legacy and changed to HD to a previously cloned for backup (which booted perfectly before) with same behaviour.  Will have to format to UEFI, but it's a very big bug to have Legacy option which does not work. Also tried another clean OS (MBR legacy) HD with no success.

Your solution has nothing to do with the problem:  Windows does NOT boot on Legacy mode. Tried with two different HD which worked well before BIOS update and also work well if BIOS is downgraded.

The ONLY way machine will boot is under UEFI.  Legacy mode is BROKEN on new BIOS, and the only solution is to repair it on newer BIOS, or delete Legacy option and warn users because machine won't boot anymore in that mode.
