Mint claims to work with UEFI, although only if secure boot is disabled

Personally, I'd use legacy BIOS like this user

The problem turned out to not be UEFI, but HP's implementation. Doesn't matter what you set as the boot in OS's (as I had changed the Windows bootloader even to point to the Debian grub-efi), HP UEFI on this model will ONLY boot to Windows.

You can do that, but you have to boot like that EVERY TIME, you cannot set it as the default. So until (IF) HP fixes their implementation of UEFI to be able to actually USE a bootloader instead of having a built in bootloader that cannot be modified to point to anything but Windows, I'm forced to use Legacy mode.

Yeah, I guess that is a more permanent solution.

You can also configure efi boot order with efibootmgr
(need to boot system with efi to make it work)
Code:
# load efi variables kernel module
modprobe efivars
# list efi boot options
efibootmgr 
  BootCurrent: 0003
  Timeout: 1 seconds
  BootOrder: 0003,0000,0001,0002
  Boot0000* Linux
  Boot0001* CD/DVD Drive 
  Boot0002  Hard Drive 
  Boot0003* Windows
# change boot order (following the list above)
efibootmgr -o  0,3,1,2
This way you can default boot to Linux with efi and press F9 to boot windows if you want

Like I said, I did that. HP UEFI ignores whatever changes you make with efibootmgr and boots windows, only windows, unless there is no Windows boot.

Sometimes efi doesn't follow the efibootmgr boot order at first time (selects old boot current), so you have to manually select boot option (F9), but after that when you reboot, it works like it should

edit: looking the web around, it seems there is indeed an issue regarding HP laptop efi bios and dual boot with Linux and Windows

The only solution is for HP or someone who knows what they are doing to fix the UEFI firmware.
