UEFI Dual Boot With Windows 10. Can't boot to Linux [SOLVED]

Folks,
I've followed these instructions:
https://wiki.mageia.org/en/Installing_o ... I_firmware
Installed, ensuring I have a /boot/EFI partition mounted. Installed otherwise as normal and I thought how much easier it was than Mageia 4 with UEFI.
However, when I reboot, it says repairing drive and boots into Windoze without giving me any Mageia option at all.
I disabled secure boot before installing. I have tried installing a second time and no difference. It flatly refused to even acknowledge anything other than Virus OS.
I should also mention I disabled fast startup, installed a third time and that made no difference.
Anyone seen this kind of thing and know what I might have not done?
Many thanks!
