At the command prompt, run the following command to disable Fast Startup in Windows 10:

diskpart
At the Diskpart command prompt, run the following command to find out the number of the partition where your Linux system is installed. Pay attention to the partition size (in GB) and the file system label to find the correct partition. Write down the partition number, you will need it in the next step.
list volume
Now run the following command on the command line to restore the GRUB loader to the selected partition (partition number_):
bcdedit /set {bootmgr} path \EFI\ubuntu\grubx64.efi`` or``bcdedit /set {bootmgr} path \EFI\pop_os\GRUB.ext
(depends on your distribution).
Restart your computer. Grub should now be restored and you will be able to select your Linux system in the boot menu.
