problem installing grub (kali linux light X windows 10 )

[belheart]

the installation finished with an error about grub-install dummy i finished the installation without grub
when running kali linux on live dvd i tried to do the following commands to install grub

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

/dev/sda* is your linux filesystem. Like mine is /dev/sda6
/dev/sda+ is your EFI partition which is most likely /dev/sda1.
Use fdisk -l to list all partitions.

but i get stuck at mount --bind /hostrun/lvm /run/lvm
i m running dvd on UEFI
+ THIS IS THE RESULT OF fdisk :

It would be helpful if you could post what exactly is reported on the failed command "but i get stuck at mount --bind /hostrun/lvm /run/lvm
i m running dvd on UEFI".

The way I see Fdisk reporting is that the system (laptop or PC or whatever) is setup to recover and reinstall Windows from sda1 when the correct keys are held at power on. sda2 looks like your EFI partition.

sda1 is pretty small, just 450MB, there is another large recovery partition at sda5.

You also appear to have two separate installs of Windows on sda4 and sda6, Your Linux filesystem is listed at sda7, not sda6 as stated in your first post.

You might have borked the Restore partitions by corrupting them, but it looks like you didn't actually get close to writing data, ie putting grub on it.

Even if the restore partitions are messed up, you can still reinstall Windows from a DVD or stick, but the built in one might be toast now. Hopefully not.

Don't delete the spaces after the sda+ and sda* entries by mistake. Spaces are important as they show the command line interpreter where one part ends and the next begins. Cut and paste is not always your friend in these cases when you have to delete one dummy character like "*" and replace it with a number. YOU CAN DELETE A SPACE BY ACCIDENT AND MESS THINGS UP.

Do you already have a menu to select between 2 installs of Windows or is a case of one Windows boot partition, one data? if you're only using one it would be useful to know which one is actually Windows.

If you have data you want to keep on a dual boot system, back it up before you even attempt to install Kali Linux as per;-

Also, it helps to have log files from installs to get support, as per;-

But I think you'll get there or back out furiously and backup your data first. Having Windows with anything sharing a hard disk isn't ideal. In my opinion. But it's not that difficult, just a bit too easy to screw the thing up and have to rebuild it.
