HP 850 G3 Grub Multiboot Ubuntu and Windows 10 on UEFI

After I installed Microsoft Windows 10, and then alongside Ubuntu, with UEFI bootabled USB disks,
last setup (Ubuntu) created Grub configuration, which is listed in HP UEFI BIOS sequence, but after power on, system get Grub Bush command prompt, without listed operating systems, like Ubuntu, Windows e.t.c., unabled to boot.



Solution: In HP BIOS setup put in a 5 (or more) seconds delay in the "Boot Options" menu. Then, when you switch on your notebook, you'll have 5 (or more) seconds to choose "ubuntu" among the possible boot options (it should be the first one).

I think that those 5 seconds delay give HP enough time to recall all UEFI and other partitions and successfully recall Grub menu.
