Hi, i installed kali linux 1 month ago and grub cos there are windows 10
installed on my hard disk, i could dual boot with grub but after bios
updated there is no grub option in my os boot manager (hp laptop). How can
i restore it? Where on the hard drive, the file of grub is stored?
HP UEFI firmware boot menu should have a "boot from EFI file" option.
The path should be something like EFI\<distro>\grubx64.efi or
shimx64.efi with secure boot enabled. When the distro is loaded, run
efibootmgr
to check EFI boot variables. If the BootNNNN entry for your distro is
missing, you can add it with
efibootmgr -c <see man page for needed options>
or by reinstalling the whole grub with
grub-install
