Howdy,

Each OEM does their UEFI slightly different...  My HP laptop has a very 
complicated boot sequence and I have to hit f9 prior o the UFI boot 
system looking for the first GPT partition.

I re-sized my Windoze partition and left empty space on the drive. After 
creating my new GPT partitions and installing linux in the remaining 
drive space, GRUB was installed in the Boot Partition of the drive.

UEFI and Windoze do not use the old way of booting from the first 
partition, so the computer will not even see the GRUB loader unless the 
f9 key is pressed to open a menu that gives a choice of booting to an 
optical drive or a USB drive or the Hard drive!  By selecting the HDD, 
the system bypasses EFI completely and reverts to a legacy boot to the 
Boot partition, where GRUB resides...

Once I get to GRUB, the system boots like the good old days..  If I do 
nothing when the computer is powered on, UEFI starts and goes to the 
menu that looks for the Windoze bootloader and boots to Win 10...

My UEFI boot menu will not allow me to boot directly to the HDD, so one 
boot system does not see the other.  It'd a goofy setup, but it works...
