[SOLVED] Grub won't install

Had Windows reinstalled, so that's working. But still can't get grub installed. I tried unplugging the other two drives and installing on the linux drive but get the same error: grub_dummy failed to install. I'd created a new partition table on the drive and repartioned the drive. I have new media for the installation as well as new isos, but still the same problem.

Any ideas?

Any ideas?

need to know the following items:
drives/partition layout filesystems flags
The contents of the efi partition

the following in your installed kali system on your internal drive
The contents of /etc/fstab
the contents of /usr/lib/grub/
The contents of /boot and /boot/grub

when you boot into the kali live
does /sys/firmware/efi exist and if so the ouput of
efibootmgr -v

Solved. After installing grub still wouldn't install. In a Kali forum someone had a similar issue. The fix was load live version then-

mount /dev/sda* /mnt
mount --bind /dev /mnt/dev
mount --bind /proc /mnt/proc
mount --bind /sys /mnt/sys
mkdir /mnt/sys/firmware/efi/efivars
mount --bind /sys/firmware/efi/efivars /mnt/sys/firmware/efi/efivars
mkdir /mnt/boot/efi
mount /dev/sda+ /mnt/boot/efi
mount -o remount,rw /dev/sda+ /mnt/boot/efi
mkdir /mnt/hostrun
mount --bind /run /mnt/hostrun
chroot /mnt
mkdir /run/lvm
mount --bind /hostrun/lvm /run/lvm
grub-install /dev/sda
update-grub
exit
umount /mnt/dev
umount /mnt/proc
umount /mnt/sys/firmware/efi/efivars
umount /mnt/sys
umount /mnt/boot/efi
umount /mnt/hostrun
umount /mnt/run/lvm
umount /mnt
REBOOT

Worked. I have to go through bios to select which OS I want, Kali or Windows, but I have Linux back
