I have installed Windows 10 and Linux Mint on two separated physical SSD Grub isn't visible while starting; I am able to load windows or Gnu/Linux by manually changing the load priority in BIOS. I have tried to change windows settings. Specially I unchecked "Turn On fast startup" option in
Control Panel -> System and Security -> Power Options -> Chose what the power buttons do
I've reinstalled grub from Gnu/Linux using command:
sudo grub-install /dev/sda1
Also I've tried to change GRUB_HIDDEN_TIMEOUT in
/etc/default/gruband updated, using command
UEFI mode disabled in BIOS.
Please tell me what can I do in this case?
